What to Compare Before Buying
- Handlebar size: This version is linked to a 25.4 mm handlebar fit, so check the bar diameter on your bike.
- Steerer tube size: It is stated for a 28.6 mm (1-1/8″) steerer tube, which must match the fork setup.
- Stem length: The 45 mm length is short, so compare it with the cockpit position you want.
- Clamp style: The 4-bolt clamp is part of the securing method, so confirm it suits your handlebar arrangement.
Compatibility, Size and Fit
This stem is presented for road bikes, MTB, BMX and downhill bikes, but the important checks are the exact handlebar diameter and the 28.6 mm steerer tube size. The fit depends on those measurements rather than on the bike type alone.
Before buying, compare the stem size with the handlebar already on the bike and confirm that the fork steerer is 28.6 mm (1-1/8″).
Before You Decide
Confirm the handlebar diameter, the 28.6 mm steerer tube size and the 45 mm stem length before choosing an offer. If your bike uses a different bar or steerer size, select another version instead.
Check whether you need the black 25.4 x 45 mm version, as the size is the key factor in choosing the right stem.
