I've seen multiple discussions of carbon 29er frames, but no such discussion of 29er rims. Current domestic carbon rims are more expensive than one of these frames. Anybody found carbon 29er clincher rims cheap?
Thanks for the info. So then it sounds like most of the published weights are victims of a rounding error, since they are listed at 1g. The figures you provided suggest that they have gotten close to cutting the brass vs. aluminum weight penalty in half, which sure makes it pretty tough to justify the iffy reliability of aluminum. Having said that, the Envy nips are internal so they require removing tire and strip to true, so it is a bit of a give and take still. Plus I still think it is playing fast and loose with the facts for them to claim they match aluminum weight.Enve use the 10mm inverted nipples from Sapim, with the claimed weight of 0.75g to 0.77g.
Sapim also have a shorter version of this nipples with a length of 8.5mm, don't recall the claimed weight but they should be even lighter.
Any rim can be drilled with a smaller hole for internal nipples if you set it up with the supplier.Hey guys been gone for a while can someone post a link for these rims with the internal nipples and also is there anything else I should also look at?
