Chromag FU40

The 40mm rise is designed to create a more upright riding position. This helps riders who feel too hunched over on their bike or those who want a more confident, commanding feel on steep, technical descents.

The FU40 features a 31.8mm clamp diameter. You will need to ensure your current stem is compatible with this standard size before installing.

Yes, like most alloy handlebars, the FU40 can be cut down to your preferred width. We recommend using a proper pipe cutter or a hacksaw with a guide to ensure a clean, straight edge.

Variable butting means the wall thickness of the alloy changes throughout the bar—thicker in high-stress areas and thinner where less material is needed. This construction method keeps the bar strong enough for aggressive riding while keeping the weight down and maintaining a responsive, non-harsh feel.

The FU40 uses a 5-degree upsweep and an 8-degree backsweep. This specific geometry is designed to align your wrists in a more natural position, which significantly reduces fatigue and strain during long rides or rough descents.
