Stems on Carbon Steerers
Stems on carbon steerers
Correct installation and maintenance of a stem is critical to rider safety. Always in the case of a direct connect-type stem on a carbon steerer, a stem placed right at the top of the steerer can put too much force on the unsupported cut edge of the steerer, possibly crushing the steerer. This is especially possible if the stem if overtightened, but can happen even when the correct torque is applied. To avoid placing the stem too close to the cut edge, always place at least one 5mm spacer above the stem.
What you should do
Always place at least one spacer above any direct connect-type stem on a carbon steerer. Appling fibre gel allows the stem to grip with lower torque to the fixing bolts, preventing slipping. Also follow the installation instructions carefully, including using a torque wrench to prevent over-tightening the steerer clamp bolts.
If you suspect a steerer has damage, replace the fork.
