I have a Tom ritchey from mid to late seventies, beautiful frame ,paints a little sketchy in some spots.low mileage on this bike.the seat tube is ovalized going Into the bottom bracket which is solid for a few inches along the chain tubes to make more rigid. Racing geometry.funny thing is it came with no decals just painted. It must have been early in his frame building days.is this a bike that's worth anything,it has really cool design features for the period.I'm working on a picture. Thanks
