Mavic XM 819 UST Rim 32Hole 26"

The XM 819 rim is a new rim in Mavic's cross-mountain family. Replaces the X3.1 rim in Mavic's lineup. They're designed for heavier duty use than a pure cross-country rim, yet still offer lightweight performance that won't weigh you down...

This rim has a special design, with internal threads (reverse threads) similar to those found on Ksyrium rims, and no nipple holes on the outside. It can be laced with standard nipples and spokes, but requires special eyelets.
