## Before you buy

- The listing's fit details name a 28.6 mm handlebar and a 1-inch steerer, but the title is broader and the size field is phrased as “Hex Lab Oversized 28.6 x 1\\" - 45mm.” Confirm both clamp diameters and the selected 45 mm configuration match your bike. The feature text also describes a 40 mm option, while the selected size and included-components text specify 45 mm. The listed brand field says Getting Fit although the product title identifies Box, so verify the exact listing identity.

- Buyers who need a stem for a different handlebar clamp or steerer diameter, or who require a confirmed 40 mm version.
