What to Compare Before Buying
- Size: This version is 110 mm. Compare that length with your existing setup or the position you want on the bike.
- Handlebar interface: The bulge diameter is 26.0 mm. Check that the handlebar area you plan to use matches this measurement.
- Angle: The stem uses a -17 degree angle. Compare that position with the riding setup you want.
- Variant: Other sizes are listed in the set, so confirm you are choosing the 110 mm version.
Choosing the Correct Version
The size range shown here includes 90, 100, 110, 120 and 130 mm. Confirm the length before choosing an offer, since stem length affects cockpit fit and position.
Before You Decide
Confirm the 110 mm size, the -17 degree angle and the 26.0 mm bulge diameter before choosing an offer. If those three details match your bike setup, this version is the one to compare.
Compatibility, Size and Fit
The 26.0 mm measurement refers to the handlebar clamp interface; it does not specify the quill diameter that fits into the fork steerer. Check that the stem’s quill size matches the steerer as well as confirming that the handlebar fits the 26.0 mm clamp.
