I was told a few years ago “frame builders can build Frames but never trust them to build a bike”
He was proven right when the next custom built bike comes in, CK bb in dry, shocking bar tape, frame was not straight so they dished the wheel over etc!
I hope not.
I don't expect a frame builder to have taste.
But I expect them to mount a rack a bit better. Also how wet will the 500$ light get.
