Bike Mechanic Confidential- Money saving tips, mechanical advice and the inside scoop that the industry won't tell you



Thinking about a new upgrade to your bike? Not sure if you need the latest gadget? Thinking about replacing your 5 year old bike with a carbon fiber wonder? Have you already looked at next year's bike catalogs? If you answered yes to at least one of these questions, you are on the consumer end of the bike industry. The customer, the end user, the money tree that keeps on giving and keeping the bike shops, online retailers and the whole entourage afloat. Need a fat bike? Just rationalize the purchase by saying "why yes, I need a bike for the one week out of the year when it snows, or to go frolic on the beach". Bike shops love you and are eager to take your money to have the privilege of working on your Colnago, oogling the bike over because it's a bike that a $9/hour bike mechanic employee will never be able to save up for. You make it rain dollar bills like Lil' Wayne in a purple drank video...

Or do you? Are you getting tired of spending an arm and a leg every time you walk into a bike shop? Not an independently wealthy trust fund kid?  Wondering if some things are unnecessary, or are things you can do yourself? Then there is hope for you, my friend. Welcome to the club of bike aficionados of the non-corporate, non doctorate inclination. Welcome to the club of do-it-yourselfers. Let me share with you some insider tips that the industry doesn't want to share.


Never use the lockout on your suspension mountain bike:  

The first rule to proper mountain biking, to getting longevity out of your suspension and to not blow out your fork seals, is to NEVER under any circumstances ride with the lockout engaged while you ride off road. Some people may argue with this notion but I maintain that unless your first name is Nino and your last name is Shurter then you have no business trying to fiddle with your lockout mechanism on your mountain bike. Set sag, pre-load and have the right air pressure in the fork if the fork has an air chamber. Those things are more important than locking out the fork for climbs and forgetting to disengage it on the descents. No suspension fork, no matter how expensive, will stand up to that kind of abuse. A good fork should last a number of years if the lockout is never used. Forget 30 hour maintenance oil changes, forget overhauling the fork and having all of the internals replaced. No lockout, no worries. You will, however, need to do is if you are a remote lockout, trigger happy fool. My advice? Take that remote lockout straight off the handlebars and chuck that thing as far as you can throw it. This leads into another suspension related, money saving tip.

Your Suntour coil shocks work just fine:

I rode a set of Suntour XCM shocks hard for over 5 years before they finally died. They came on my first full suspension bike which went through some of the local hard trails in the area and even went off road in Georgia and North Carolina. The failure of my shocks was due to leaving them locked out and taking them through a technical descent. Otherwise I don't think I would have had any problems with them. I currently have another set of Suntour XCR 32's  on my full suspension 29er. These shocks are super value coil shocks with oil dampening rebound adjustment. True to their reputation they have given me excellent performance and have taken everything I have thrown at them so far, from technical rock gardens to 3 foot drops. The only upgrade that would make sense, if only to save a little weight and add a little stiffness, would be a set of Fox 32's.

Why the emphasis on Suntour? Rockshox seems to be leaving the coil suspension game to try to be a more premium brand the way Fox is. Rockshox at one time made some of the best coil forks that could be found on the market, such as the Judy, Tora, Dart and XC28 models. These had the ability to be self serviced and fine tuned depending on what kind of suspension coil they had. They seem to be exiting the entry level price point and their products are usually found on bikes starting at around a grand. So that leaves Suntour with the $400 to $800 market, the target which most beginners or new kids to the sport would be able to afford.

Was there anything wrong with coil shocks in the first place? No, in fact once the industry got it right and built a bombproof, indestructible coil shock like the Rockshox Judy, they realized that they weren't going to sell any more bikes, because the thing would just not break. They needed to find a graceful way to sell us another bike so they gave us longer travel options, tapered head tubes and a more affordable mid-range solo air option. Also counting on user error, they gave us the lockout feature on our forks, because that's how they guarantee repeat business.

The moral of this story? As we say in Texas, if it ain't broke, don't fix it. Ride your bike to the ground and o-nly upgrade things to add comfort to your ride, like your grips and your saddle. Shocks are a part of the bike and represent about a third of it's overall value, so it's a big ticket item to upgrade just for the sake of upgradeditis. 

Unless you park your bike outside, never replace cable housing: 

Cable housing becomes damaged only if it is cut, severely bent or exposed to the elements and becomes rusted from the inside out. Ride a lot, but leave your bike stored indoors in a dry place? You will never have to change cable housing, no matter how many times a mechanic brings it up as part of a performance tune. Not necessary.

Dawn or Simple Green cleans better than that bike wash stuff they sell at the shops: 

Forget buying bike specific cleaning products. All you need is a bucket with water, a rag, a brush, some dish washing soap or an environmentally friendly cleaner like Simple Green to get the job done. It will cost less and give a better clean than the stuff the store sells.

Stop shaving, using chamois butt-r and slurping gels:

The pro's are the people you see on TV. They are not you and I. We are but mere mortals that have to work for a living and must carry on with dignity and self-respect. We will neither see or appreciate the aerodynamic gains of having our legs shaved or our rear ends slathered in chamois butt-r. Hair stubble hurts, no joke. Not even Peter Sagan shaves his legs anymore.

Emphasize needs and wants, and pick the right tool for the job: 

Looking for a new bike but already have 20 bikes in the garage? Let me stop you right there. You don't need a new bike. Maybe a kid in Malawi needs a new bike, but you certainly don't. Chances are that you already have the tool needed for the job required. With  a little modification, an old mountain bike can become a drop bar gravel grinder or a commuter with some street slicks. Don't have a road bike but want a road bike? Take a rigid mountain bike and put drop bars on it. That bike will hold you over until you are averaging 18-19mph with the fast guys in the club. Looking for your first bike? Think about all realistic scenarios that you will be riding your bike. These days there are many good options in the "one bike that does it all" category. They might be heavier, have knobby tires or made of steel, but one good bike can last a lifetime.

Mid-range is the best range: 

Not sure if your 9 speed Shimano Sora or Shimano Alivio groupset is up to par with that of your friend's Dura Ace or XTR groupsets? Have you found yourself being talked out of your triple chainring crankset to go to a 1x? Have a solid set of wheels but saving up for some carbon ENVE's? Do you find yourself blaming your bike more than your time off the bike for performance loses?

My go to road bikes for group rides lately are a 1988 Schwinn Tempo with downtube shifters, a 6 speed freewheel, 32 spoke count wheels and a steel frame. My other is a 2012 Cannondale Caad 8 with an aluminum frame and Shimano Tiagra shifting. I can average 20mph or more on the fast rides in my area and stay with the rest of the pack, on both bikes. My go to mountain bike is a Fuji Outland 29er full suspension mountain bike that I bought new. I have less than $1,400 invested between all three of these bikes. So while I'm not saying that my bikes are cheap by any means, all three of those bikes might equal the price of what the industry advertises as a "performance" or "race specific" bicycle. The difference between the bikes that I own and a $1,400 bike ends at the price tag. For $500-$800, or about half the price, the same kind of bike can be had. I don't mean a dumb down version of the $1,400 bike. I mean oftentimes, the same performance can be had out of a mid-range bike. The mid-range package might be less flashy, less desirable and less advertised. However, it might have parts that are more durable and have less proprietary technology on it that makes it easier to maintain. What if I told you that 9 speed groupsets were the sweet spot? 9 speed groupsets for road and mountain have the best price point, best durability, best functionality, best reliability and oftentimes the best design. There are also the staple groupsets of mid-range bikes. Something to consider whether you are a beginner cyclist or a seasoned rider eyeing their next bike purchase.


Don't be a poser: 

There are other cyclists besides Chris Froome. Don't be that guy that shows up to the club rides in full Team SKY jersey kit. Not only does that reek for noob behavior, but you will be on the wrong side of history later and will look back on how much of a tool you were for being such a bandwagon Team SKY fan-fan.

When in doubt, Youtube it: 

You can learn literally anything on Youtube, even bicycle repair. Don't want to learn? That's fine too. We in the bike industry appreciate your dollars. However, I will suggest at least learning how to do basic maintenance on your bike. Because when all of the shops in the area are a month out on repairs, you don't want to drop your bike off at the shop because of a flat tire. 

These are some insider tips that the bike industry isn't talking about. Hopefully this has been a helpful article for some of my readers out there. Till next time!

How to Restore a bicycle- Part 1-Dissassembly and rust removal

How to Restore a Bicycle-
Getting off that rust is a must!

It's been one week since my last blog post, but it already feels like forever. I want to apologize to my disgruntled fans for having kept them waiting on my every word for the very next thing I  have to say. In my defense, I've been busy. With what, you might ask? With my next project, restoring a blue 5 speed Schwinn Cruiser. It lived it's life on the ocean and became a beach bum. Now it bares the consequences of it's laid back lifestyle with a collection of rust on it's frame and parts. In fact, this bike is so rusty that I think I'll just refer to it as "Rusty".

Bicycle newbies, mechanics and restorers need to pay close attention to this article if you are trying to revive a Rusty of your own. This article is going to cover the steps I take to get rust off a bicycle and also the tools and chemicals I use for the job.

Things you'll need for this job:
- A socket wrench set with metric and standard sizes
- A bicycle repair stand
- A large universal wrench, the kind you would club somebody trying to rob you with
- Needle nose pliers
- A cable cutter, preferably the one Park Tool makes
- A pedal wrench. Mine is a chain whip and pedal wrench combo, found at your local bike shop.
- A few buckets
- Savogran Wood Bleach or any wood brightener that contains oxalic acid
- Rubber gloves, goggles and a respirator mask if the fumes are too intense.
- Baking soda
- A ventilated area or a space in your backyard where the neighbors won't mind
- Allen wrench set
- WD40, steel wool, and wire brushes
- A Phillips and Flathead screwdriver 
- A clock in the room and a coffee maker, just 'cause.

Okay so each restoration project is different in that the parts of the bicycle are all mounted differently. So instead of going into detail general bicycle diss-assembly, I'm going to talk about the diss-assembly for this bicycle. Here's what the bicycle looked like, after I took off the bolt on wheels.

Ol' Rusty getting stripped down for the rust bath.

This fork has seen better days.

This chainring, believe or not, will shine after the oxalic acid bath.


  
Taking the bike apart is the easiest part depending on how you look at it. Where there's a bolt, use a socket wrench, a screw, a screw driver. But it is also very labor intensive. Turning parts that have don't want to be turned because of rust can be a real challenge. My secret weapons for stubborn parts are my bicycle repair stand and WD40. Whenever possible, use the bicycle repair stand to your advantage. Even if its to remove a pedal from a crank arm, you can set the crank arm in the vice and bear down on the bolt of the pedal to screw it freely off. This will save you from having to bend over constantly and in the long run will save your back. 

I will, against all bike snobbery wisdom, use WD40. I don't rely on it exclusively, but to get parts to move on old bicycles, its a must to have around. This single piece crank set shown on the picture took about half an hour to remove. The reverse threaded side was stuck onto the frame by rust. With some WD40 I was able to work at it little by little until the crown started turning. (FYI: the non-drive side on these crank arms is always the reverse threaded side. Always remove the bolts and crown on this side of the bike, then slide the crank arm out the opposite end through the bottom bracket.)

The best way to learn how to put the bike back together is by making a mental note of  what you remove. "Does that washer come before, or after the ball bearings?" for example. Save every little part taken off because you never know how important that part may be or how difficult it might be to replace.

After I remove all the main parts such as the wheels, crank arms, fork and seatpost, now I'm ready to tackle the small stuff. I take a pair of cable cutters and cut the exposed cable on both ends of the brakes and the shifter and derailleur. I leave the housing intact because I will need to know how much housing to buy in the future. 

Finally with all parts taken off, the frame is ready to be sent for sandblasting and powder coating. This is an acceptable strip down of the frame at this point of the restoration.

Once the frame has been stripped down, a painter should have no problem removing the remaining rust  and repainting the surface.

I'm not going to lie and say that I know how to do powder coating, because that would be over promising any potential clients of mine. I do know where to get it done at a reasonable cost, and paint jobs like these aren't exorbitantly priced luxuries. The paint job is, however, a major expense in the restoration process. Be ready to shell out at least a Benjamin to get a frame like this painted to match. I will post pictures of the results of the powder coating on my next article.

Now that all the parts have been removed, it's time to put that rusty pile in a chemical bath. The chemical you will need is called oxalic acid. It is a compound mostly used to bleach wood decking. You can buy it at some hardware stores in its concentrated, or crystallized form. They also carry a diluted liquid version which takes longer to remove the rust. At first I went to my nearest Lowe's and bought a gallon of Cabot Wood Brightener which contained oxalic acid. I set the rusty parts in a bucket and filled it with water. Then I started adding a few ounces of the wood brightener. After leaving it overnight, the parts looked almost the same, so I added more copious amounts of the stuff into the bucket. At the and of the day I saw the water turning yellow which is a sign that the oxalic acid is doing it's job. I will leave it again overnight and see the results tomorrow. 

If you are using Savogran Wood Bleach oxalic acid, two tablespoons should be enough to tackle a batch like the one below. This acid needs to dissolve in hot water when it is first used.

My first 48 hour Oxalic Acid bath using liquid wood bleach.
Reader be advised, when using oxalic acid, please take the necessary safety precautions. This acid is a poison. It should not be left in a garage or an area with no ventilation. When cleaning parts off with this acid use rubber gloves. To dispose of the acid you will first have to neutralize it using baking soda. Pour small amounts of baking soda at a time until the water sizzles out, then you know the bath has been neutralized. After the acid has been neutralized, it can be poured down the drain. Also, when working in close proximity to the acid, use a respirator mask. Exposure to this acid has been linked to kidney failure and joint problems. Again, take the proper precautions. 

In my next article I will feature the after photos of the acid bath, the finished powder coat and decals on the frame, and a few more other steps in the restoration process. Stay tuned for part 2 and possibly a part 3 on how to restore your bicycle.

Jonathan and Taryn: Crusing into the Sunset

Jonathan proposed, Taryn said "yes!" Congratulations guys!

Who said a photographer's work is done in the winter? I was fortunate to get this last minute booking for this young couple. Due to the reduced amount of daylight in December, I had to be creative on some of the shots that I took. Here are some of the results.

You will notice that I also ventured towards the surrounding area around the canals for this photo-shoot. Las Colinas is full of great architectural buildings and sculptures and provides interesting photo opportunities.

A day with Johnny and Dorcas

Photography tips with Johnny and Dorcas


It's all about the details! Brides love the details that go into making their special day.
I found this shoe shot to be one of my more sucessful examples yet.
One of my colleagues recently invited me to do an assist for our mutual friend's wedding. It was a pleasure to take the time to photograph this young couple. Here are a few highlights of the day's activities.


Shooting in a dark reception room will require some creativity and some additional lighting other than your carry on flash. Be prepared to "take out the big guns" with your studio lighting and remote flashes. 2011 Jonathan Guzman

Brides love the details on their wedding dress. Be sure to at least have one picture like this in the album.
Every once in a while it's good to shoot a wedding for fun and let someone else do the worrying. Part of networking as a photographer is learning how to get along with the other kids on the block (fellow photographers) and sometimes doing a good deed is it's own reward. Either way each wedding will add 2 to 3 shots to your growing portfolio. These are the one's I think I will keep.

How to make Beautiful Timed Exposures

The Wonders of Timed Exposures
"Taking pictures at night without flash"

"The Cima Club" Downtown Las Colinas Copyright 2011 Jonathan Guzman

Here's a list of things you will need:

Tripod-Sturdy, Aluminum. Able to withstand a windy day. I use a Bogen Manfrotto 3021 Series
Lightmeter- must be able to meter incident light  (The Sekonic Flashmaster or Gossen Luna Pro are a favorite among photographers, although I find the Sekonic easier to use. 
Camera and Lens- Single Lens Reflex, Twin Reflex, DSLR, or Rangefinder. Must have manual focus capabilities, bulb setting or shutter delay capabilities up to at least 30 seconds.
Shutter Release Cable- Optional but highly recommended, especially for cameras that do not use vibration reduction for Image Stabilization features (such as film).


What to do-
1.Set your ISO to where you will have the finest grain possible. (For film users, find a film with low ISO). Preferably 100 to 200 ISO would be recommended.
2.Place the camera on the tripod securely. Connect the shutter release cable if you have one for your camera. For film users, this is a must.
3.Meter the incident light that is coming from the subject. You do this by pointing the light meter towards your subject, with the head facing your subject. Incident right refers to light coming from a specific direction, ambient light is light coming from all directions. There are normally two different light meter heads on the light meter to measure each one.
4. Plug or dial in the light information into your camera. (Example: the light meter says to shoot at 2.8 for 30 seconds. Therefore, my lens aperture will be 2.8 and I will keep the shutter open for 30 seconds either with the bulb setting or shutter delay.
5. Focus in your subject. If your subject is a landscape, just set the lens manually to the figure 8 symbol on your camera. If it is up close, you will have to manually focus it in the dark, preferably with the help of an assistant to flash a light source on it, so that it will be in focus. Auto focus will not work properly and has a high failure rate in this kind of photography.
6. Snap a picture, then wait, then release the shutter release cable (if applicable).

The end results will look like the pictures below:
Texas State Fair Ride. 2011 Jonathan Guzman
Downtown Fort Worth. 2011 Jonathan Guzman

Who said there weren't any cowboys in Texas? Normally I don't use this photo as an example, but here we have an example of a one second exposure with the flash firing. Notice that all the background colors are there, as well as the "ghost" of movement in the image. Its always good to show the exception to the rule.

Following these guidelines and making them your own will result in more beautiful and interesting pictures at night or in low light settings. Please feel free to comment your questions and I will be glad to answer them.

Venetian Style Photo-shoots

A Little Piece of Italy In My Own Backyard

As a photographer I try not only to specialize in one thing only. Weddings are a seasonal item and the bulk of good weddings will occur between March and June. This is because, depending on what part of the world you are from, these are the most temperate months of the year. September is another popular Month, and in Texas specifically, there can be warm weather all the way into November. By November, highs can still be in the mid 80s in Fahrenheit. 

So this brings me to my next point, What does one do the rest of the year? Does one simply stop taking pictures? A hobbyist probably will but a professional does not. That is because even when there are no weddings to shoot for the year, a professional is always trying to leave the door open for next year. This involves the process of getting referrals and marketing your business to other potential wedding clients in the future. This can be done, not only at the wedding itself, but in places you know people will be preposing. One such place are the canals in Las Colinas, that happens to be in reasonable distance from me.

I like to say I have a piece of Italy in my own backyard. On an evening stroll through the river walk you can the these gondoliers singing Sinatra or Yanni songs to their star-struck guests on board, which are usually engaged in romantic kissing to even know if he is singing out of key or not. 

Seeing that there were no other photographers around already doing it, I booked a cruise for my wife and I for our 2nd year anniversary. Upon making the reservation I was able to talk to the co-owner of the business (these small businesses are usually family run operations, even the reservationist might be the owner at times). I let them know I was a photographer and would be interested in working with their clients so that they had pictures of their wedding proposals, anniversaries, or other events that they would need a photographer for. This company loved my material and brought me in as their event photographer, and I have been able to build a great relationship with them as well as their clients.

So whether it is an arboretum, botanical garden, river walk, city park, or any other place of considerable beauty that people like to go to prepose, this is an opportunity that is knocking on a photographer's door. If you are a photographer looking for business then stop worrying about search engine ranking and website appearance. Instead go to the people directly and solicit with them. I know other photographer colleagues and competitors with great websites, but no business. This method of marketing works, and it will be a source of extra income in those slow months of wedding photography.
