Lightweight Rims?

Since 2001, over 90,000 cyclist's have joined Cycling Forums to discuss topics from general cycling to equipment, training, racing and travel or vacation destinations (especially in europe during the tour de france). We also feature an great deals in our online store, 100's of articles, classifieds and product reviews.

I've got a pair of 28 hole HF Record hubs with Mavic Mach 2 CD 2 tubular rims that I'm thinking of rebuilding with something lighter than the Mach 2s.

I'm thinking Velocity Escape Ambrosio Crono and other sub 400g rims and maybe even Aerohead clinchers / lighter spokes, c-xray DT Revo etc.

Any other ideas would be welcome and also whether or not you think 28h Cronos and the like are too light for an 87kg rider on a good concrete track.

Thanks Jay.

on track, as you are not fighting gravity, weight is not much of an issue (look at the weight of a BT frame). the mavic rims you already have are stiff and strong, and therefore good for track. think about the difference a couple of hundred grams makes to performance compared to loss of rigidity

I remember an old teammate of mine, about you same size. He wanted lighter, went with 32h Saavadra's. Hitting turn 3 at the end of a race they collapsed under him as the pack was hitting near top speed, taking out about 1/2 of the pack. He spent a couple of nights in the hospital with 2 other guys who were T-boned sliding down the banking.

That said, the rims you mention are a bit stronger, but you can't win the race if you don't make it to the finish line!
