The Race Face Aeffect R Stem, equipped with a 35 mm handlebar clamp, 32 mm length, and a sleek black finish, is built to be an All-Mountain (AM) and Enduro workhorse. Designed for modern, aggressive bike geometries, its ultra-short 32 mm length shortens the bike's cockpit, enhancing steering response and providing maximum control on steep, technical descents.
Component Specifications
Length: 32 mm (the shortest, snappiest extension available in this line).
Handlebar Clamp Diameter: 35 mm (oversized standard for high-leverage bars).
Rise Angle: 0 degrees (maintains a low, centered aggressive stance).
Material Construction: 3D forged from robust 6061 aluminum, then CNC-machined.
Weight Profile: Extremely lightweight at just 131 grams for the 32 mm size.
Application Rating: Fully rated for Down-Country, Trail, All-Mountain, Enduro, and high-power eMTBs.
Core Mechanism & Design Features
Top-Lock Faceplate Interface: Utilizes a Top-Lock clamp design where the rider torques the top two faceplate bolts flush against the body first, eliminating gap variation before tightening the lower bolts. This ensures even stress distribution on carbon bars.
Continuous Spine Aesthetics: Features a seamless industrial design where a continuous metal spine integrates the faceplate smoothly into the stem body.
eMTB Ready Strength: Forged and machined to endure the higher torque, weight, and trail abuse associated with full-power electric mountain bikes.
Lifetime Warranty: Backed by the Race Face Lifetime Warranty program, which covers damage from trail crashes.
This stem is a trusted choice for riders who demand precision, durability, and performance on the most challenging trails.
