Local cycling legend and even more prolific photog Steve Z has done a fairly good side by side shoot out of two single speeds...similar in appointments but one on 26" and the other on 9'ers. It's Curtlo versus On One (anyone know the URL for them?) folks.
I will get to scope out my Revolver 29'er next week! Mike is going to bring it up to San Anselmo for me to scope out. Stoked. Going to dismantle the YBB and migrate the parts.
