NITTO B840AA-SSB | Lightweight Riser Bar That Flexibly Absorbs Road Vibrations

Enjoy agile handling while absorbing trail vibrations.

This riser bar is perfect for situations where you want to move your bike exactly as you intend, gently softening the impact transmitted through the handlebars, whether you're navigating root-filled sections or forest paths littered with stones.

The NITTO B840AA-SSB achieves both lightness and appropriate flexibility by designing the tube with a thin wall thickness. Its modest 21mm rise and 8° backsweep create a natural hand position, providing agile control from trail rides to city commuting.

Features

• Thin tube wall design achieves both appropriate flexibility and light weight.
• Designed to easily absorb minor vibrations from the road surface, suitable for trail riding.
• Uses different materials from the B809AA-SSB and B801AA-SSB to achieve further weight reduction.
• Modest 21mm rise naturally lifts the handlebar position.
• 8° backsweep supports stable control and allows for a comfortable wrist position.
• 31.8mm clamp diameter, easy to match with modern MTBs and custom bikes.

Despite its flexible design, it maintains a clear operational feel, providing a balanced ride that makes handling the bike easy even on rough surfaces. It's a great option for those concerned about trail vibrations or arm fatigue.

Since the 21mm rise doesn't drastically change the handlebar position, it's also suitable for customizations where you want to slightly raise your upper body while retaining the nimble feel of a flat bar. We can suggest combinations with stems and bike frames.
