Oh and I dinae need three inch wide gazothingies, I have a set of 24 x 3" Vuelta DH tyres NOS, very aggressive tread pattern, they fit with clearance my On-One 456 frame
The guy whose created that bikes on Retrobike somewhere and I believe he's from Edinburgh but other than that seems to have no desire to have anything to do with MacRetro but who could blame him
I really like that but I think it might be a little flexy for a fat bike, I hate mine as a 26-er from that perspective, good forks and a more rigid rear triangle might make a big difference though.
