I have a lovely pair of silver 700c Mavic MA3 clincher rims laced to black Campagnolo Mirage Q/R hubs complete with an excellent condition 9 speed cassette(not sure what other speed cassettes they can take, not really a Campag man). Wheels are in fantastic condition, hardly any rim wear, butter smooth hubs and perfectly true. I'd like £100 posted for them or I'd like to swap/trade them for a set of black tubular shallow profile rims laced to Shimano 10 speed compatible hubs. WHYG?
