Bike Fitting


The RETUL Fit Program is the only complete bicycle fit system using products and methodology that are ergonomically designed and scientifically tested to improve power, endurance, and comfort.

Working with Dr. Andy Pruitt and the Boulder Center for Sports medicine, our fitters have extensive training and certifications from Specialized Bicycle Components University (SBCU).

Our team of Retul Master Fit Technicians are trained in road fitting, aero/triathlon fitting, mountain bike fitting, advanced physical assessments and cycling specific injuries to help you become one with your bike and allow you to ride with comfort for as long as your lungs and legs desire.

We do fittings on bikes for every discipline. Road, Mountain, Cyclocross, Gravel, Triathlon, and Time Trial

If the Shoe Fits

For maximum power transfer on the road or trail and for exceptional comfort on a spin bike, we recommend clipless cycling shoes and pedals. With stiffer soles and the ability to click into and out of your pedal system easily, cycling shoes make your ride and your workout more efficient, more effective, and more comfortable. Never get stuck in a toe cage again!
