I must admit that this is the first carbon fiber framed frankenbike I’ve ever seen. The combination is bizarre. A time trial frame converted into a fixie cruiser.
My biggest question is what would you use this for? Time trial frames are light and aerodynamic but really uncomfortable. Fixies are usually urban bikes known for their durability. Carbon fiber frames are not known for rugged durability.
All that said the current bid is only $10.50 with shipping of only $60. At that rate it might be worth it just to get the parts for use in a more suitable fashion. Maybe there is a 30 speed cruiser bike out there that needs a transplant.
