Chas Roberts TT - early 70's

Bought the frame on ebay, after some thorough investigation and with the help of Ron Cooper (RIP) Chas came forward and said he'd built it... Reamed out siezed seatpost, removed siezed BB/Shifter band/front mech cleaned up the worst of the rust and built with an unholy mix of vintage kit. Being a TT frame there's front mech cable routing so a cable stop was bodged. The wheelbase is insanely short and there's more toeverlap than my tarck bike. Angles are steep too so you have to concentrate on steep descents, but I'm really loving it.

Maybe this was built by Geoff Roberts?

Chas said "it's definitely one of ours" I took this to mean his or Charles snr. If Geoff was building in 1973, I guess it could also be by him... My guess is that it's Charles senior
