Race Face Aeffect R 35 riser handlebar, 780 mm

Race Face handlebar. Needs from your bike: Stem bar-clamp diameter (fitted stem). Provides: Handlebar clamp diameter (fitted bar).

The Race Face Aeffect R 35 riser handlebar, 780 mm is a handlebar (component). It requires 1 thing of a bike — Stem bar-clamp diameter (fitted stem) — read from Race Face. It provides Handlebar clamp diameter (fitted bar) to the parts that mount on it. On every bike page its verdict is computed from those requirements against the bike's cited facts: when a fact is missing the answer is "unknown", never a guess.

Requires — Stem bar-clamp diameter (fitted stem)35 mm
Provides — Handlebar clamp diameter (fitted bar)35 mm

Stem bar-clamp diameter (fitted stem) is safety-critical: a wrong answer could hurt you, so we say "fits" only when the bike's fact is confirmed by two independent sources. With one source the honest answer is "unknown"; with none it is "unknown — safety-critical".

Does this part fit my bike?
