Truing Your Frame - Fit Your Bike to Avoid Injury from "Outside Bozeman"

Fit your bike to avoid injury

While cycling is relatively easy on your joints, because of the constrained position and

repetitive nature of the sport, it can be easy to develop overuse injuries.

These injuries are often attributed to ramping up training mileage too quickly or being improperly positioned on your bike. Training errors can be avoided by following a proper training schedule. Fitting your bike to your body—not the other way around—helps achieve proper positioning.

It’s best to see a professional bike-fitter at a physical therapy clinic or your local bike shop, but here are some tips to alleviate common pains associated with cycling.


Achilles’ Pain
Cause: foot positioned too far back on pedal
Solution: move foot forward on the pedal by moving your cleat further back

Arch Pain
Cause: foot positioned too far forward on pedal
Solution: move foot back on the pedal by moving your cleat further forward


Anterior Knee Pain
Cause: saddle too low and/or too far forward
Solution: move saddle up so there’s a slight bend in the knee at the bottom of the stroke

Posterior Knee Pain
Cause: saddle too low and/or too far back
Solution: move saddle so there is a moderate to slight bend in the knee


Lower Back Pain
Cause: stem too short
Solution: get a longer stem


Neck Pain
Cause: bars too low
Solution: raise your bars by getting a more upright stem or moving headset spacers from the top of the stem to the bottom

By Tiffany Coletta

Birds are chirping, sun is shining (today at least!) and snow is melting. Time to think about hitting the trails and moving our bodies with some springtime trail fun. Here’s a way to enjoy Southside Bozeman while supporting our beloved trails and the Gallatin Valley Land Trust. Southside Saturdays is brought to you from our friends at Outside Bozeman and Sola Café.

Southside Saturdays Outside Bozeman Sola Cafe

A springtime trail celebration to benefit GVLT.

Gurgling streams winding through aspen groves, mallards lifting off into the bright blue sky, smiling Bozemanites strolling beneath towering cottonwoods—these are the sights and sounds that await those who venture into Bozeman’s Main Street to the Mountains trail system. With nine miles of trails between Kagy and Goldenstein, and 50 miles between Main Street and the national-forest boundary south of town, there are countless acres of open space to explore.

Hike, run, or ride the southside trails, fuel up at Sola Café, and take a photo with an issue of Outside Bozeman. Each meal purchase and photo sends a buck to GVLT. It’s a springtime celebration in support of the Gallatin Valley Land Trust (GVLT), the organization responsible for the creation and maintenance of these and other in-town trails.

Event Details:
1. Sola meal purchase must be at least $7 to qualify for the one-dollar donation.
2. Photo must be taken on southside trails (between Main St. and Goldenstein). Upload photos below.
3. Event runs from the second Saturday in May through the end of June.
4. Kickoff celebration Saturday, May 10, 10am at Sola Cafe on the corner of Kagy & S. 3rd.
5. Best photo wins a nose-dive into the Outside Bozeman Treasure Chest.

What is a Professional Medical Bicycle Fit?

By Tiffany Coletta

What is a Professional Medical Bicycle Fit?  A Medical Bicycle Fit is aimed at injury treatment and prevention for cyclists of all abilities, from recreational to racer.  If you have neck, back or knee pain, saddle sores, or hand and/or foot numbness, your bicycle probably doesn’t fit you properly.  Correct cycling position is key to improving performance, optimizing comfort, decreasing pain and preventing injuries.

Medical Bike Fit appointments include biomechanical evaluation to determine cycling posture and pedaling mechanics, video analysis of body positioning to detect problems in cycling form, comprehensive muscle, and a joint and bicycle evaluation to improve you’re cycling mechanics and reduce risk of cycling-related injuries. Flexibility and strength testing as well as exercise prescription for injury prevention and pain reduction are also included, followed by static and dynamic assessment to correctly position the saddle, stem length and angle, pedal-cleat interface, among other adjustments.

Most insurance plans can be billed if you are experiencing pain as a result of your cycling activity.

Jason Lunden, DPT, Sports Clinical Specialist, is a Certified Bike Fitter and provides Professional Medical Bicycle Fit appointments in our Bozeman office.
