bought one classic RB but can't tell manufacturer cause previous owner respray and remove everything (no mark, decal or anything on frame), any expert can help me on this ?
Bike detail :
105 SLR brake (Caliper n lever)
105 RD (7 speed), FD, shifter (index),
Suntour "Custom" dual Crankset.
Suntour drop bar.
Chrome cromo fork (this he din't respray).
Exage hub with made in taiwan HJC wheel.
Series (at BB) :
S 9XXXXXXX (can't see cause of paint job)
Agreed on the Crankset and FD telling the true tale.
My money's on something asian from around 1980. I know it's not much relief to hear this, but there's rarely much resolution to these origin threads when they're about midlevel bikes like the one in the OP.
