Educate yourself on Trek and your Trek bike. Search answers to other riders' questions, or submit a question yourself.
I am looking to purchase a new bike. What size frame should I get?
It is too difficult for us to make an accurate recommendation as to what the best size for you would be without actually seeing you on the bike. We recommend visiting an authorized Trek dealer and being fit in person. They can help you determine the best size for you. Taking a test ride on different sizes is also helpful when trying to decide what's most comfortable for you.
Does Trek offer sponsorships?
At Trek we are passionate about the sport of Cycling and the promotion of good health and well being. In conjunction, Trek has extended sponsorship to programs, events and athletes that reflect our philosophy. Each year Trek receives hundreds of inquires pertaining to sponsorship, in order to evaluate, process and select the best qualified applicants Trek relies on our dealer network.
If you are interested in obtaining sponsorship from Trek Bicycle please start with your local Trek retailer. Athletes and programs strongly allied with our dealer network are given priority.
How do I find the model year and/or specs for my older bike?
Due to the high number of models we have produced over the years, your local authorized dealer can best identify the model year of your bike. Unfortunately we do not have older specs electronically archived. If you need a particular component spec for your bike, please visit your local dealer or send us a digital picture and we would be happy to research it for you. You can find a dealer near you by using the Find a Dealer section on our website.
My bike was stolen. How can I find my serial number?
If you send us the full name, address, model number, and approximate purchase date you would have put on the card along with approximately when you registered the bike we would be happy to do a serial number search for you.
I crashed my carbon bike, is it OK to ride?
Please see our Safety First Carbon Fiber Crash Replacement and Care Information . If you have any doubt about your Trek carbon fiber product, please see your nearest Trek family dealer
I can't find my computer's instructions online. How can I get a copy?
If you send us what model (Sensor, Sonic, Radar, Fusion, Basic) computer and any numbers on the back, we would be happy to send you a copy of the instructions.
I have a crack in my frame, what do I do to find out if it is covered under warranty?
The first step is to take your bike to your local dealer to be evaluated. They can then determine if it is a warranty issue or not. Many cracks in carbon frames are non-structural paint cracks. If it is a structural crack , they can start the process to have the frame returned to us to be repaired or replaced. If it is not warranty, they can let you know what options you have.
If you have crashed your Trek carbon bike please see our Safety First Carbon Fiber Crash Replacement and Care Information and do not ride the bike! Again, take the bike to a Trek dealer for inspection.
I'm experiencing chainsuck or chaindrop on my full suspension bike, what should I do?
All mountain bikes are prone to experience chainsuck or chaindrop. In most cases if you are experiencing these issues on your Fuel or Liquid, they can be remedied at your local Trek dealer.
Here are some of the common causes of these issues and possible solutions. It is important to remember that a bicycle is a machine, and this list attempts to address mechanical problems. It is not likely that occasional shifting issues will disappear completely from any bicycle.
1. Derailleur adjustment
2. Drivetrain maintenance (dirty or worn chainrings, un-lubricated or worn chain)
3. Component incompatibility (mismatched chain, chainrings or front derailleur)
4. Shifting habits (unplanned or high tension shifts will cause problems) 5. Inclement/severe riding conditions (increases occurrence and may lead to ongoing shifting problems on any bicycle model)
6. Some models of Fuels shipped with incompatible chainrings on the stock Bontrager crank. The offending rings can be identified by the 'V3' stamp on the middle ring itself. This ring can cause or add to shifting issues and should be replaced with the 'V5' version chainring. These replacement rings can be obtained through your local Trek dealer at no charge.
7. Frame alignment
The first six items on this list can be addressed by a local Trek dealer and by improving shifting and maintenance habits.
If these have been addressed and shifting performance does not improve then you may need a frame alignment evaluation. Alignment should be checked by an authorized Trek dealer who can work with our Technical Services department for a solution. The likely solution is for an authorized Trek dealer to install Adjustable Chainline Bushings that allow the dealer to tune the alignment of a Fuel.

Why aren't the weights listed in the specs on the website?
We understand that this is an important piece of information that many riders factor into their buying decision. We have chosen not to post weights on the website for a couple of reasons:
1. It is probably most accurate for a rider to simply weigh a bike in a shop as opposed to us listing it on the website, because there are many variables that affect the weight of the bike- i.e.- frame size, decal/color options (some designs weigh more than others, with or without pedals, and production/component variables. Tires vary widely in weight, even though they come out of the same mold- same with tubes. The actual tubing and weld material can vary a good bit, depending on the style of the welder and the amount of weld rod added. Bottom line, we would have two choices, estimate heavy so we would never be called liars, or go light, knowing that we would be wrong on occasion.
2. Many of our competitors do list bike weights, and we know that they are not accurate - i.e., we know they have chosen to list a lighter weight than 99% of customers would be likely to get. For the rider simply looking on the internet, Trek bikes may not compare as favorably as they would if you actually weighed actual bikes.
3. Last, we encourage riders to remember that anyone can make a bike lighter, but Trek will only sell bikes that are 'responsibly light', meaning that all the components have passed strict impact and fatigue testing. We spec our bikes to be safe and last a long time, so be sure to compare company warranties when you are comparing weights.
What do I do if I crashed my carbon frame or part?
Please download and read our carbon fiber care & maintenance flyer(.pdf 596k) and our information on Caring for the Carbon Steer Tube on your Fork flyer (.pdf 922k). Carbon fiber is a great material for producing premium bike frames and parts. However if a carbon part or frame experiences an impact it requires more expertise to determine its integrity than is needed for a comparable metal part. If your carbon part or frame has been crashed, we strongly urge you to have it assessed by your local Trek dealer as they are equipped to look for damage. Carbon fiber will not dent like metal but will crack which may lead to failure.
We do offer a Crash Replacement/Carbon Care program via our dealer network for carbon frames up to five years old which gives a rider a credit toward a new frame/part. To take advantage of this program contact your local Trek retailer.
