Just seen wjat you mean. You'd not get 3m down a track around here before the back end has jammed. Needs a bendy seat tube.
Edit : prototype rushed frame I guess
A few notes: this bike is the first sample. The 433mm chainstays are the same as the 27.5 bike. For production, they will be lengthened. Also, Fat Chance is waiting on custom drawn stays for production, so they’ll change a bit as well.
