11/1/20: To reduce the spread of COVID-19, we are not offering Bike Fittings at this time.

Precision Fit

Unleash your potential with the proven process of the Trek Precision Fit system. You won’t believe what a proper fit will do for your riding experience. A personal fitting experience will address your specific needs, giving you a tailor-made solution that will lead to countless hours of faster, more comfortable, and more enjoyable riding.

1. The Interview

The process starts with an interview to determine where you are as an athlete and where you want to go. There is a large difference between the fit you want for sprint distances (you’re on the bike for about 30 minutes) versus the fit you need to go a full 112 miles. Of course in both cases you’re always looking to stay aero for the entire ride, but we as athletes tend to be willing to suffer more over a shorter time period, thus allowing us to get much lower and more aero for a sprint distance event.

2. Physical Assessment

Part two is where the massage table comes into play. Once the interview is complete, it’s time for the physical assessment. The assessment checks your current body morphology across eight areas. Everything from your foot position to your stability is tested. There is nothing like having a tri coach cheer you on while doing a plank in front of an entire bike shop crowd!

As you can see in the images below, you are going to complete a number of tests for range of motion and flexibility. While we’ve been through plenty of fits, the Trek Precision Fit’s off-the-bike assessment definitely stands out.

3. Shoe Setup

Step three is shoe setup. When it comes to your shoes, a proper fit is about more than just cleat placement. It’s also about making sure the shoe properly fits your foot. This can end up being one of the most important parts of the entire fit process for some people, with a solution as simple as the addition of insoles to his current shoes.

4. Starting Position

Next up is step four, setting up the fit bike with your current fit coordinates.

5. Lower Body Setup

Trek breaks up the fit into a lower-body and upper-body setup. The lower body starts with your saddle selection. One of the more interesting tests you do as part of the physical assessment is a sit bone test. A pressure-activated board is used to determine where your sit bones are. Once the sit bone width is determined, a saddle can be selected. Now it is time to determine the saddle’s position relative to the bottom bracket. The fit bike allows our Certified Bike Fitter to easily adjust the saddle height and location.

The Trek Precision Fit system uses a 2D motion capture system to determine your current position versus what it sees as the optimal position. The cameras also help to hone in on getting the saddle position just right in order to optimize leg and knee angles.

6. Upper Body Setup

Finally we move on to the upper-body setup. Here we determine the proper stem height and reach. And with a tri bike, you are also determining armrest width and position as well as extension length. For those buying their first tri bike, this is a great time to also try different extension shapes to see what you like best.

7. Review and Follow-Up

You’ll end your session with a detailed document that defines your fit and a follow-up appointment to guarantee your satisfaction.
