It’s a 80’s 501 R’ Dawes wildcat mtb - 26” Wheel and full mtb clearance for big tyres but think it possibly has room for 650/700 wheel depending break caliper reach and tyre et al
*Looking back could have gone more riv with the paint but this also nods to ritchey in the bronzey gold
Interesting build and it certainly looks fun to ride. Was the Dawes frame
originally a hybrid or touring bike?
