No nonsense.

When redesigning the Aeffect stem, Race Face set out to capture the reliability and light weight characteristics that we found in the original model, with added strength for an all mountain and enduro riding, and shorter lengths that cater towards modern bike geometry. The Race Face Aeffect R 35mm stem offers just that, plus the ability to run an extra stiff and beefy 35mm handlebar. Machined out of forged 6061 aluminum, the Aeffect R is lightweight without sacrificing strength, and reinforces your cockpit with a burlier bar than smaller 31.8 stems, which won't provide you with the same stiffness and security on the rougher downhills.

  • Burly, light, and pocket friendly stem for all mountain and enduro
  • Secure your 35mm bars to your rig for aggressive riding
  • Machined from forged 6061 aluminum for lightweight strength

Very Durable - Exactly what I wanted

I've put it through the wringer

I wanted a shorter stem than what came with my cheap XC bike and I upgraded to the RaceFace Turbine bars which is a 35mm bar so this was perfect and cheap enough to not make the upgrade an issue.

A durable modern Stem

I've put it through the wringer

This alloy stem can take a beating and is compatible with larger 35mm bars. The shorter length stem pairs up nicely with a modern enduro bike, inspiring confidence from the first ride.
