I forget exactly what the frame and fork are, but the frame is a Schwinn that was originally a hybrid with a garbage heavy, steel fork. I'm not saying steel forks are garbage and heavy, but that particular one was terrible, cheap, and heavy. Also ironic because I dislike Schwinn, but really like this bike. Giant made an identical bike with a different fork, though, so I'm guessing they just contracted/bought a bunch of frames from them. The fork is a high end cyclocross fork that I swapped out. Components are Ultegra RD, Dura-Ace FD, SLX cranks, Tektro 720 brakes, Cane Creek levers, hand built wheels with Dyad rims and XT rear hub and dynohub. Between touring and commuting, I've done thousands of miles on it and it's been a comfortable, solid bike.
