What to Compare Before Buying
- Clamp size: Check that your stem is made for a 31.8 mm handlebar.
- Width: The stated 780 mm width is important if bar width affects your riding position or available space.
- Rise: Choose between the 20 mm and 35 mm rise versions according to the position you want.
- Cut-down marks: The marked sections support width reduction, so confirm whether you want to use the bar full width or trim it.
- Material: The bar is 6061 aluminium alloy, which may matter if you are matching parts in an existing setup.
Choosing the Correct Version
Check the rise before ordering, as both 20 mm and 35 mm versions are stated. The width and 31.8 mm clamp size are also part of the exact fit decision.
Before You Decide
Confirm the 31.8 mm clamp size, choose the rise you want, and check whether the 780 mm width suits your bike before selecting an offer. If you plan to trim the bar, review the cut-down marks first.
