Thrifty Bill's advice (post 18) is always good. There's nothing that special about those RSX 7 speed brifters. When asked a valuation question, posters generally try to give their best estimate of what the bike is worth on CL, not what they would pay for it.

Cleaned up, it's worth $200-$250 in the spring. $300 is a tough price for a vintage bike and there is nothing that special about this bike.
