Matthew Bowne asked about SC 'Record du Monde' rims and their appropriateness for track use?
According to my old information, these rims weighed 330 grams (have one and it checks exactly); the truly light SC rim was the 'Medaille d'Or' which, at most, weighed 280 grams. Be careful with the MdOs (smooth style; smooth road; lower spoke tension) but I expect much more forgiving nature from the RdMs.......My own preference runs to Mavics from the same era, and although they were < in general> heavier, they were also more robust and provided longer and more trouble-free service.
By the way, the width of the SCs is slightly <20mm.
