Here is a shot of the rear triangle on the V2 Prototype. Look at those sexy hydro formed chain stays. We curved the gusset in between the chain stays to give you better clearance with a fully slammed rear wheel. This is the only gusset used on the bike. We chose to use beefy tubing instead of throwing gussets all over the place. The photo above is of a 26 x 2.3 almost fully slammed in the drop out. Got quite a bit of room to play with even with the 2.3.
