Item # RIT000D
Ritchey WCS Carbon C-260 Stem $159.95
Typically, a stem body and faceplate each wrap 180 degrees around the handlebar. Ritchey's WCS Carbon C-260, on the other hand, wraps a full 260 degrees. This distributes forces more evenly across the handlebar, faceplate, and stem body for a stronger, safer, and lighter interface.
The WCS Carbon C-260's body is 3D forged from 7050 aluminum that's internally machined and enhanced with Ritchey's Matrix carbon exoskeleton. The enhanced alloy/carbon structure allows the 100mm-length C-260 to achieve a sub-115g weight. Another way Ritchey kept this stem so light is by using T-20 Torx bolts.
Instead of two five- or four-millimeter hexes to clamp the steerer tube, three smaller T-20 bolts end up not only distributing forces more evenly, but they also save weight. The CEN-approved WCS Carbon C-260 Stem is claimed by Ritchey to be 14 percent stiffer than the full Alloy C260.
The Ritchey WCS Carbon C-260 Stem is available in the Carbon color and in sizes 70, 80, 90, 100, 110, 120, and 130mm.

So you can't install without unwrapping...
So you can't install without unwrapping your bars and taking the levers off at least one side? If so that's hardly an improvement.
You don't need to remove the lever and only need to unwrap the tape on top of the handle bar. The 31.8 diameter of the handlebars is only on the middle where the stem clamps on. May not fit all handlebar though.
