Atlas 31.8mm Stem

The Race Face Atlas Stem routes load through its own body rather than the four faceplate bolts. A 31.8mm clamp mates to an interlocking faceplate that keys directly into the stem, moving stress off the hardware and into the machined 6061 aluminum. At a 40mm stack and zero degree rise, it drops the front end without adding bar height, a detail worth noting when dialing in an aggressive fit.

What Our Gearhead® Experts Are Saying:

"I checked bolt torque after a hard case on a gravity lap and found it exactly where I left it, which told me the load stayed in the stem body and never reached the hardware."
