RaceFace Chester Riser Bar

The RaceFace Chester Riser Bar requires a stem with a 35mm clamp diameter. Before purchasing, verify that your current stem matches this measurement, as it is not compatible with standard 31.8mm stems.

While carbon fiber is generally lighter and can offer more vibration damping, this 6061 aluminum bar is built for durability and impact resistance. It is an excellent choice if you prioritize longevity and a stiffer, more direct feel over saving a few grams of weight.

Triple-butting means the wall thickness of the aluminum varies throughout the bar. It is thicker at the stress points near the clamp for strength and thinner in lower-stress areas to reduce weight without compromising structural integrity.

Yes, the 780mm width can be trimmed to your preferred length. We recommend using a proper pipe cutter or a hacksaw with a guide to ensure a clean, straight edge.

The rise you choose depends on your preferred riding position and bike geometry. A 10mm rise keeps your front end lower for aggressive climbing, while 20mm or 35mm options provide a more upright, comfortable position that can help with confidence on steep descents.
