3D Bike Fit,

"3D Bike Fit is awesome, I can't recommend them highly enough. I hadn't had a proper bike fit in over 8 years and coming here was long overdue, I can't believe I waited so long. Kevin is so fun to work with and I had a blast. I was blown away by the depth of knowledge he had; decades upon decades of bike fitting and bike racing experience and he is open and willing to share all of it to create the best experience for those he is fitting. it was truly engaging to go so deep on so many topics related to my position, physiology, and equipment. I had no idea there were so many changes I could make and I'm already feeling more comfortable on the bike. About 3 weeks after my fit, I completed a 400 mile ultra distance event in 25 hours of riding time. No pain or soreness anywhere and I think a lot of that has to do with Kevin dialing in my position. I will be returning here for any and all bikes I buy in the future so I can get everything in the perfect position."

"Kevin did a great job with my Retul bike fit. I'm a recreational rider with a bit of wonky geometry, and he took the time to work through the particulars of my riding style and get me aligned so that I was pedaling more efficiently. He also put together a couple of custom insoles for me which have been great at getting my Bigfoot feet in the right spot."

"I’ve gotten three fits from Cesar and use the Form Cycling saddles on all of my bikes. I can’t recommend them enough! It took me a few rides to get used to the many great changes Cesar made during my first fit, but I could quickly see improvements in my endurance and comfort in the bike. Best of all, my upper back pain disappeared! There is a reason Cesar is in such high demand! Thanks!"

"Cesar is the best of the best! He totally has perfected his craft. He took the time to learn about my riding background, areas of strengths and limitations, all while delivering the best customer service. The variety of tools and technology they use to provide the utmost thorough bike fitting is incredible. I got a new stem and feel totally realigned on the various minor tweaks that were made. I feel so much more comfortable and confident in riding, and appreciate all the insight Cesar had to offer. I recommend them to anyone who is looking for that detailed 1/1 experience. THANK YOU, CESAR!!"

"Cesar is excellent. They're very thorough and know what they're doing. They have their own line of parts, and they are really good, so feel free to get a new stem, seat post, foot bed, etc there. Just great stuff. And you get a video of yourself riding your bike at the end!"
