Race Face Aeffect R Stem

This stem is built specifically for all-mountain riding. It is engineered to handle the aggressive, technical terrain you encounter on trail rides, focusing on a balance of durability and responsive handling.

The Aeffect R is designed for a standard 1-1/8-inch steerer tube and requires 35mm diameter handlebars. As long as your bike uses these common modern standards, it will be compatible.

A 0-degree rise keeps your handlebar height neutral, which is ideal for modern mountain bike geometry. It helps maintain a balanced position that feels stable on steep descents while keeping the front end planted during technical climbs.

A 50mm length is a sweet spot for modern trail bikes, offering a responsive, snappy steering feel without feeling twitchy. It helps quicken your bike's reaction to steering inputs, which is particularly helpful when navigating tight, technical sections of trail.

Yes, it is built as a workhorse component. Race Face designed the Aeffect R to provide a stiff, robust connection between your bars and fork, ensuring it can withstand the rigors of aggressive riding without unnecessary weight.
