Hi, i've got a set on sprints. Mavic tub rims, barely braked on, silver, chromed butted spokes laced to small flange campag record hubs (with dust caps in middle of hub). Regina 6 speed block. Need to double check spec, but from memory that's right. I was going to take the wheels apart and sell the hubs, but if you want the whole wheels they'd make a good set. Chrome on the spokes is a bit pitted, and the block needs a tool, the pin holes on the block are gnarled from trying to remove with a diy tool (my fault). Bought the wheels as an extra set with a complete bike from a guy who said he'd done a few time trials on them in the 80s and that's about all the use they've had. Hubs are buttery smooth. Rims are perfectly true, block ticks perfectly. Be a nice set of wheel if you use tubs. £40 posted?
