Light clincher rims......?(4 posts)

Light clincher rims......?Simon
Apr 14, 2001 5:56 AM
I am looking for a lightweight clincher rim for a road bike I am building, but can't seem to get any lighter than Open Pro's. I know there good, but my mountain bike rims weigh less.
Any suggestions?
Thanks for your time,
Simon

The Aerohead is about 10 gm lighter than the Open Pro - not much of a savings but they are about $10 cheaper and a better design, IMO. It seems to me that FIR makes a rim around 395gm, though that may be pushing the limit. It shouldn't some as a huge surprise that there is a certain minimum design limit that can't be exceeded, and around 400 gm is it for a clincher rim. Two very obvious reasons your MTB rims are lighter are 1) smaller diameter and 2) rim has to take only about 1/3 as much pressure from the tire (140+ psi for a road rim, 50+ psi for MTB) so the side walls can be thinner.

Good comments about wheel weights!

Of the rims I've bought (open pros, aeroheads, Sun ME14) the aeroheads were the lightest. The stiffest rims, however, are the Suns.... but in reality most of the built wheel strength comes from the spokes so absolute rim stiffness isn't the be-all-end-all.

I have two wheelsets built with Velocity rims. One is 28 hole and other is 32 hole Dura Ace. Both sets are great wheels. If your into colors, you cannot beat the Aeroheads for different color options.
