What to Compare Before Buying

- Clamp diameter: The stated 31.8 mm clamp diameter needs to match the stem interface.

- Version: Check the B2 designation and bead blast black finish if you need this exact variant.
Compatibility, Size and Fit
This handlebar uses a 31.8 mm clamp diameter, so the stem interface needs to match that size. The 38 cm width is another important check for fit and riding position. If you are replacing an existing bar, compare both measurements before choosing an offer.
Before You Decide
Confirm the 31.8 mm clamp diameter, 38 cm width, and B2 variant before choosing an offer. Also check that the ergonomic bar shape and bead blast black finish match the setup you want.
Check the Complete Cockpit Fit
Matching the 31.8 mm stem clamp is only one part of a handlebar replacement. Before changing bars, check that your existing brake and shift controls can be mounted and positioned on the new bar, and compare its shape with your current setup. If you cannot confirm those details, ask a qualified bike mechanic to assess the fit before installation.
