Race Face Atlas 31.8mm Stem Black, 65mm/0 Degree, One Size

The Race Face Atlas Stem sends crash impact through its own body instead of the mounting bolts. An interlocking faceplate locks directly into the stem, so a hard landing loads the machined 6061 aluminum body rather than the hardware holding it together. What Our Gearhead(R) Experts Are Saying:"I clipped a rock ledge hard enough to fold a lot of stems and mine came off clean, no crack in the faceplate and no play in the bolts."
