Bike Repair Hints from the Pros

Share this post Twitter Facebook Tumblr Email Posted September 16, 2011 in Tips

A Lemond Alpe D'Huez comes thru the door, and I ask the customer, "How can I help you?".  The customer says, "Well, I think my bicycle needs a little TLC".  At first glance, you could tell the bike had been ridden a fair amount.  One tire was flat, and the bar tape was coming un-raveled.  The first time a mechanic looks at a bike they are trying to get a wide perspective of what needs to be done.  Its difficult to see everything until the bike is set-up on the workstand, at eye level, and carefully inspected.  

The purpose of this article is to help you diagnose the warning signs of a bike that is in need of "TLC", as our customer put it.  Below are a series of photos showing what mechanics see as serious warning signs of extreme wear, potential failure, or perhaps total replacement of bicycle/frame.

Note:  These are only a small sampling of what could be going on with any given bicycle.  If you're bike looks like this... I suggest you get ready for a very large repair bill.


Chainrings/Drivetrain:

The front chainring is extremely worn, as pictured next to a brand new chainring behind.  Notice how "pointy" the ring teeth are on the black, worn ring and how flat topped the new ring (rear) looks.  What happened here is the bike was ridden too long with a worn chain.  Chains, cassettes, and chainrings ultimately will wear at the same rate.  Depending on riding style and conditions, the rate can vary.  However, common practice is to have your chain checked for wear at a minimum interval of 400-600 miles.  Again, wear rates can vary from rider to rider, so you'll want to pay attention to what kind of rider you are.  Best case, you have a trained professional keep track of this for you.  This could have been avoided by replacing the chain at the appropriate time.  The case here, we needed to replace the chain, cassette, and chainrings.  Ouch!


Wheel Spokes/Nipples:


Serious corrosion present here around the spoke nipples, and the nipple bed of the rim.  Scored grooves in the brake track.  These wheels arent in great shape.  Likely to have a failure soon.  This also could have been avoided by simply wiping down the rims, spokes, and nipples thoroughly with a mild soap and water solution.  After the wheel dries a teflon or lightweight oil treatment would have been good also.  


Frame/Cables:


This bike hadnt been into a shop for maintenance in a very long time.  This cable didnt work at all.  Totally frozen.  Just needs a little "TLC" and she'll be back on the road again, right?  


The corrosion on this frame/bike never stops.  Its everywhere.  In fact, too many places.  This last photo could be the most alarming.  Corrosion is failure waiting to happen, and the last place you want your frame to fail is at the headtube.  If this frame were to suddenly split at the headtube, while riding, it would be a very nasty picture.  This was a very nice bike frame, but the owner apparently didnt think to highly of it.  At least not enough to get it into a shop that will take care of it for him. 

These types of things can happen to any type of bike.  Nobody is immune to regular maintenance of their bicycle.  Either you do-it-yourself, or you have your LBS do it, it needs to be done.  Personally, I know how to paint a wall, but that doesnt excuse me from not painting my house.  It needs to get done!  Therefore I hire a painter and its done.  Next.  

If you're training for an event or simply have only a few hours a week to ride your bike, you dont want to spend this valuable time riding a poorly running bicycle, or worse have something fail on you.  If you know its been some time since your last maintenance, dont wait much longer, these things can only get worse.

If you have any questions about our repair service, perhaps this page can provide some answers, or just stop by the shop with your bike.

New Bike: Hints for a Successful Outcome

Share this post Twitter Facebook Tumblr Email Posted September 02, 2011 in Tips

Many factors go into a successful outcome when you're purchasing a new bike.  Below are a few things we think you should look for when you start "doing your research".

1. What kind of riding do you want to do? Experience level, and your approach to cycling are important.  Are you motivated by weight loss, speed or fun?  Are you looking for a social outlet?  Where you live is important, because the riding out of your front door is the easiest to do.  The more you refine these thoughts the better we can help guide you into the proper bike.

2.  You'll need a good mechanic!  Whether you end up riding a singlespeed cruiser or an electronic shifting road bike, you're gonna need an experienced bicycle mechanic.  Knowing how to turn a wrench is the least important trait of a good mechanic.  A good mechanic wants to understand you as a rider, willing to search for "hard to find" parts, and has an extensive riding background of his own.  Well qualified shops/mechanics will most likely be qualified by Park Tool, the industry's top manufacturer of cycling specific tools.

3. Sizing vs Fitting.  The size of the bike you ride is critical for comfort, power generation, and the best overall riding experience.  We pride ourselves on being knowledgeable in both bike sizing and bike fitting.  Sizing a bike is NOT the same as fitting a bike, even though the terms are often used interchangeably.  We have developed a process for sizing a bike and use the same process on everyone that comes thru the door, and the same fitting process going out the door.  You can rest assured that we will dial you in.  In most cases, where you buy your bike is more important than the bike you buy.  

4.  Buy what you like.  You need to feel good about what you're buying, even if its not available.  One small example, the color of the tires, and bar tape, can be a reflection of your personality.  So, you may opt to change that out to give your new bike a bit of flare.  We will happily do this for you.  Other things such as shape of the handlebar (standard vs compact), seat, and perhaps wheels can, and sometimes need to be changed, to make the overall package that much better.  

5.  Demonstration.  We see lots of people getting back into cycling after a long respite.  Braking and shifting systems, and pedal systems, have changed dramatically over the years and you should get quality instruction on how to use them prior to delivery.  Dont be afraid to ask questions, even if its a topic you dont understand.  

6.  Community.  Outside of having the proper equipment, you may want to get plugged into a community of other cyclists.  We're a little different in this respect as we discovered the need for a club environment for racers and recreationalists alike can merge together.

These are just a few points on what we feel makes up a successful outcome in a bike purchase.  Cycling is more than a sport, its a lifestyle.  We're here to help guide you, give us a call.

How do I ride comfortably in the cold weather?

Share this post Twitter Facebook Tumblr Email Posted August 10, 2011 in Tips

Stay inside?  NOT!

Some positives come out of the cooler weather such as changing colors of foliage, less bugs, and less chance for overheating.  However, it takes just a little more preparation.  Here's some rules to live by when riding in colder weather.

1.  Hydrate -  Too many riders take this for granted when dealing with the cold.  Insulated bottles work well in the cold too.  Drink fluids regularly even if you dont feel like you need to.
2.  Layer It Up - Too much clothing and you'll burn up, too little and you'll freeze.  Experienced riders know that dressing in several light layers allows you to remove some to regulate temperatures.  From inside-out, wear a base layer, middle insulated layer, then a shell on the outside.
3.  Stay Dry - Unlike riding in the heat, you do not want to be wet in the cold.  Engineered fabrics to wick moisture away from the skin are ideal.  Cotton should be avoided.  
4.  Control The Temps - Starting out with less clothing than you think, with the option to add more later is the best way to go.  However, arm warmers and leg/knee warmers offer great flexibility in managing your body temperature.  They can easily be rolled down, or stuffed into a jersey pocket as the temperature flucuates.  Some offer extra SPF.
5.  Cover Your Head - The absolute easiest way to regulate your body heat is to cover your head.  Most of your body's heat rises out thru the top of your head.  Just like warmers, head gear can easily be removed and stuffed away when you warm up.

3 Steps to Get More From Your Workouts

Share this post Twitter Facebook Tumblr Email Posted August 10, 2011 in Tips

Who hasnt thought they could do better or get more from their workout session or race?  There's alot to think about when training for triathlon or cycling events, but here's 3 key areas that deserve your focus.

1. Trim up the rotating weight!  I'm not talking about the weight around your waistline, rather the weight that is rotating on your bike!  Think about it... Hubs, rims, spokes, tires, tubes, pedals, chainrings, chain, crank, bottom bracket, shoes, cleats, list goes on... Regardless of what bike you have, the best bang for your buck are new wheels.  Most complete bikes come with very basic "training" wheels.  Just about any wheelset purchased aftermarket would be an upgrade to this type of wheel.  The most practical way to experience what wheels can do for you is to discuss your riding style, mechanical abilities, and budget with our staff and we can recommend some options, as well as, set up a demo.
 
2.  Dress the part!  This is often the most overlooked area.  Articles such as an aero helmet, or shoe covers can gain you 1-2 mph.  Shoe covers alone can gain you 5-10 seconds every 10-15 miles or so.  Of course we dont always have time to put on shoe covers, but an aero helmet is a no-brainer!  Properly sized cycling or tri tops are also very important.  If your top drags in the water, you are wasting energy, much like if your cycling top or jersey is flapping in the wind you're giving up speed.  A shoe that helps you get it on and off quickly is also something to consider.  Velcro straps instead of buckles even.  

3.  Feed the beast!  Your body is an engine, and engines need fuel.  A rule of thumb we follow: Per hour, consume 2 calories for every pound of lean muscle mass.  For example, if you weigh 200 lbs and are 20% body fat you need 320 calories per hour (200 x .8 x 2 = 320).  This formula is NOT absolute, it is merely a guideline.  Bottom line you need to be properly fueled in order to get the most out of your engine.  Consuming an adequate amount of clean burning calories before, during, and after will greatly improve the quality of your workouts.

Foot Pain? Shoes, Cleats, and Orthotics are key!

One of the most common complaints among cyclists we see is hot feet.  Hot feet is typically known as the burning sensations near the toes during a ride.  This sensation is mostly due to pinching of nerves.  It can stem from a number of situations, but I recommend checking your shoe size, cleat placement, and the soles of your shoes.

Shoe Sizing
Cycling shoes are made to be as stiff as possible to allow power transfer during the downstroke (plantarflex) AND to fit snugly enough to aid in the upstroke (dorsiflex) as well.  Cycling shoes stretch very little, therefore you shouldnt expect them to do so during the break-in period.  When shopping for new shoes, I recommend wearing the same sock you intend to ride in, while you try them on.  The end of the day is usually a better time to try on shoes cause your feet are swollen from the day.  I also recommend trying on shoes with an appropriate footbed as they can require additional space.  Sizing guidelines vary, but you should end up with a shoe that fits snug around the heel, but allows your toes to move freely.  Any reputable bike shop should spend plenty of time with you while you try on shoes as this is a very important piece to the cycling puzzle.

Cleat Placement
The cleat is the first link in our chain of body parts that propel us on the bike.  It is often overlooked as a source of problems.  It is very important to have your shoes and cleats working as a single unit to allow the power generated by the hips to transfer thru our feet and into the crank.  The term "ball of the foot" is a misleading concept that should be shot dead.  I encounter many riders who are slamming their sesamoid bones 5000 times per hour because someone told them to put the cleat on the ball of their foot.  Its a general term, or rule of thumb, that is a simple starting point.  Discomfort in our feet, however, can be due to improper bike fit in relationship to the cleat position.  Its more complex than one might assume.  The cleat is link #1.  Another factor to consider is your pedal platform.  Wider platform pedals (ie.Speedplay's) distribute force better than a smaller counterpart.  Not saying one is better than the other, but to reduce discomfort we pay attention to everything, and each case a little different than the last.

Carbon fiber shoes today are made of improved composites that are stiffer than ever.  Carbon soled shoes made as early as 4 years ago are not as stiff as a comparable carbon shoe today. There are many studies that have illustrated how "un-stiff" carbon soled shoes were in the early stages compared to nylons and plastics.  Today that is not the case with new "lay up" technics and improved composites.  Therefore, if you have an older pair of carbon shoes and you experience discomfort, that may be the underlying cause.  Time for new shoes!

Footbeds
Often riders will exhaust all their options, in regards to hot feet, before finally giving in to a custom orthotic.  This is actually flawed logic as footbeds can offer many more benefits than a last ditch attempt to aleviate hot feet.  We feel footbeds do not have to be expensive, and you should not need a Dr's appointment to get them.  Those days are gone!  Today's advancements in medical technology allow us to have these products OTC (over the counter).  Good foot health is crucial for any athlete and a shoe alone is just not custom enough.  As cyclists we require optimal forefoot balancing, deep heel cups, and metatarsal separation.  Sole has been making an outstanding product, and has served our customers well over the years.

Regardless of how much attention you pay to your feet there will always be the chance for discomforts.  If you cycle long enough, or run enough, you can actually wear the fat padding on the bottom of your feet thin.  If it gets to this you need to seek out medical advice.

Hope this helps!

Demo Bikes and Wheels!

Share this post Twitter Facebook Tumblr Email Posted January 21, 2011

Here at On Your Mark, we do our best to inform our customers and give them the most information possible to make the best purchasing decision.  Its near impossible to have every color, size, and model available in stock.  Therefore, we have our coaches, and sales staff hand select the equipment we make available for demo.  

Demo's are available by appointment only.

For wheels, we offer Rolf Prima's Vigor.  Talk about versatile, these wheels will excel in any environment.  Fast rolling wheels could be the best single improvement for your bicycle next to a professional fitting session.  We can slap these on your bike in minutes.

Rolf Prima Vigor


In the complete bike department, we offer the Jamis D29 Pro and the Bianchi Via Nirone Carbon.  

For the discerning road rider there's nothing finer than italian craftsmanship.  You can expect comfort in the saddle all day long with this model, and it shares the same characteristics as the Infinito.  We only have this in a 55cm.


If trails are more your style, perhaps you'd like to see what 29" wheels are all about!  Sure footed yet lightweight, great pricepoint with components found on only the hotest race bikes, the Jamis D29 Pro will impress you.  We have two of these available, one in 15" and another in 17".
