This is the highest end bike I've ever had. Uses an On One frame, the previous owner built it up from the ground I believe. Dude obviously knew bikes pretty well. He converted it from the a single speed to a 2x8 16 speed configuration, and it's only had a round 30 miles since then. Listed on craigslist today, my dad noticed it, and several hours and $300 later it's sitting in my basement.
Total upgrade from my last bike, which was OK. But this one is sooo much lighter and with the slimmer wheels (and different gear ratios) it's a breeze to ride.
This is my old bike.
