After 29 years of riding road bikes, I finally decided that it was time to invest in a proper fitting, and decided to give the Guru fitting system a try. Tonights ride (22.5 miles, 1243 feet) was the first post fit.
I have never felt better on a bike. Not even close.
The only changes to the fit I had developed for myself was a seat that was 8mm higher, and 3cm forward, and moving from a 42 cm handlebar to a 44cm. I also changed saddles from a Fabric Scoop Flat, to a Radius. The stem, and it's position, stayed the same, as did crankarm length. I was sure that the new position would take some getting used to, but I was wrong. I immediately was incredibly comfortable, and had the best little ride in a very long time.
I just wanted to share this, and to thank Steve Herrera at The Cyclery in La Mirada, CA for helping out. He's one of the few shop owners that I've run into that gets it.
