Race Face stems are designed for use with 1-1/8 inch steerers, and 31.8 mm or 35 mm diameter handlebars (depending
on the stem model). The handlebar diameter is marked on the inside of the stem handlebar bore (35 mm shown below).
Ensure that the dimensions of your stem match the steerer and handlebar you intend to use.
Note the handlebar clamp bolt torque value etched on the inside of the stem handlebar bore. Once you install the
handlebar, this value will not be visible.
