Purely Custom Fit Bike


"As a competitive triathlete, I spend a lot of time in the saddle.  From early season base miles on a road bike, to long rides and time trials in the aero position of a tri bike, it is essential for my performance that I am comfortable mile after mile.  After a previous fit with another company and less than desired results, I was referred to Bob and the SICI fit of Cycle Therapy.  For me, the results after my fitting were immediate.  The adjustments that were made led to increased comfort and therefore longer, stronger, and more beneficial training sessions.  I would recommend a fit from Bob and Cycle Therapy to anyone looking to improve their riding experience.  From the recreational rider to competitive athlete, you will not be disappointed with a decision to be fit using this method!"

"I cannot thank you enough for my fabulous bike fit!  I have had other bike fits before, but none of them gave me the results and comfort I now have on my bike since I had my bike fit by Bob.  Since the fit, my power numbers have significantly increased and that nagging lower back pain I felt on rides prior to the fit are just a faded memory.  You were absolutely worth the 520 mile round trip it took from Utah to Twin Falls for you to work your magic.  Plan on seeing me this summer with cyclocross bike in hand for a fit as well!"

"Several weeks ago I came in for E-Soles.  Bob helped and fitted me -- spending about 1 full hour with me.  Thank you for that!  Riding is once again fun -- without pain or numbness.  I appreciate your help more than you'll ever know.  Thank you."

Rachel -- Twin Falls
