Hi I've built 5 motorized bikes now and I think I have the bug. Wife bought me a GT2 frame for my birthday. So what rims would you suggest for building a "race" bike.
Get some nice wide 24" rims or runna 24 in the back and a 26 up front... the 24" rims in a 26" frame also make more room for wider tires.
If your budget allows... these felt rims are nice and wide... and built to last... http://www.chubbysbikes.com/shop/felt-24-wide-rimmed-front-wheel-black
