Aero, Retro, and New Bike Fittings
After a short interview Rasmussen Bike Shop takes 12 measurements of your body to determine exact cockpit length, saddle and handlebar height as well as fore-aft position. We will find proper KOP (Knee Over Pedal alignment) while maintaining optimal power. Laser guided pedal stroke alignment to ensure a cleat to knee to hip alignment.
Custom Frame Design
For the serious cyclist looking to build one bike to last them the rest of their life. With Fit Kit Pro software, your body’s measurements, and a thorough understanding of your cycling goals we are able to build the geometries needed for a custom titanium frame from Litespeed.

Video and Photo Review
We rarely get to see ourselves ride. To help your understanding of the fitting process Rasmussen Bike Shop uses a video camera and a 20 inch LCD flat screen to provide you a real time image of your cycling posture. We will also provide you with pre and post-fitting examples using digital video and photography.

SpinScan Analysis
Is one of your legs stronger than the other? How well do you apply energy throughout your pedal stroke? Using the CompuTrainer SpinScan, we work with you to identify problems in your pedal stroke, and help you eliminate those inefficiencies through instruction, training, and practice.

Posture Analysis
Maintaining proper posture will determine your comfort and control while cycling. We will examine your current riding position while under load and pinpoint any areas that can be improved. Our goal is teach you about core-centered cycling which will maximize your energy use and efficiency.

Specialized Body Geometry
Specialized shoes, gloves, saddles, clothing, and much more were designed by today’s leading mind in bike fitting Dr. Andy Pruitt of the Colorado Center for Sports Medicine. Rasmussen Bike Shop offers all of the Specialized Body Geometry products to custom fit every aspect of your cycling experience.

Aline Foot Bed Systems
ALINE's patented Bilateral Foot Alignment Suspension Technology (BFAST) reveals your personal power position and unleashes your maximum energy and performance. ALINEs support your foot's natural arches, reduce impact force, and guide your foot into the proper position for total body alignment. Custom-fit ALINE's maximize your natural athletic advantage through increased power and control while saving undue wear on the rest of your body.

Wedge Service
If you use a clipless pedal system you may be exposing your body to potential knee injuries. Approximately 96% of the population has what is known as a forefoot tilt. This is where the front of your foot is not flat but rather has an angle or tilt. Most clipless pedal systems do not accommodate this tilt, instead forcing the foot into an unnatural flat position. Foot/Pedal misalignment can cause many cycling related problems including injury and fatigue. The Wedge evenly distributes foot contact with the pedal enabling you to pedal with better alignment resulting in more power and improved comfort.

Aerodynamics
Aerodynamic drag is the biggest force acting against a cyclist under most conditions, and is of primary importance in time trial and triathlon events. For such races, optimizing an athlete's power to drag ratio is essential. During your bike fitting we will address any aerodynamic concerns and capitalize on all available tools to limit your drag and increase your speed.

Installation and Purchase Discounts
During your fitting we may find you will be better suited with a different pair of shoes or a perhaps a new stem. Rasmussen Bike Shop will provide a 20% discount on all purchases and installations that may arise from changes made during your bike fitting.

"I can really feel the improvements from the bike fit at Rasmussen Bike Shop! My legs feel powerful and efficient with the shims that Donny put in, and my position is much more comfortable."

Jay, Expert Mountain Biker

I have been cycling for only about 3 years and never had a bike fit done. I had heard about this service but to be very honest, I was pretty skeptical. Rasmussen’s Bike Shop has always treated us wanna-be triathletes with the best service and has gone above and beyond with taking care of the Des Moines Tri clubbers and their families.

So, after the boys down as Rassy’s put together my new road bike for me, I met Donny and we talked about the bike fit…..Again, I was hopeful that it would help, but skeptical. We scheduled the fit and Donny was very professional in every aspect of this service. Everything he did to adjust, fit, fix, measure, tilt, slide, turn, and twist was right on. I ended up having him order some “jammer aerobars to use for 3 triathlons this year that involve a lot of climbing and are more suited for a road geometry and he helped my fit be “spot on” from the beginning. At my last triathlon I ended up having one of the top 5 bike splits out of over 400 people and felt great for the run.

So, after starting out the process hoping that it was worth the time and money, I can encourage everyone……it is definitely worth both!


Reed, Triathlete

I've put about 120 miles in with the new fit (70 getting use to it and 50 hard miles last night) and it feels good. Actually, it feels great. I am so much more comfortable on the bike now.

Greg, Road Cyclist

I'm so glad I got fit for my new Specialized road bike at Rasmussen's. I was trying to decide between a couple of different sized bikes. Not only did getting fit tested help me decide what bike to order, but then my bike was also set up to fit me personally. Because we knew how long my arms were, for instance, Donny could figure out how big my ideal cockpit size was and fit my bicycle accordingly. I feel so comfortable on my bike now, it virtually took the guess work out of it! I don't have strains in my back or tightening up in my knees because everything moves smoothly. It makes riding my bike so much more enjoyable, not to mention making me more effective in the saddle. Thanks so much to Donny and the crew at Rasmussen's for setting me up!!!
