BBB BHS-29 HighSix 31.8 Trekking Adjustable Stem
Dial In Your Perfect Riding Position
The BBB HighSix OS Adjustable Stem is built for riders who want greater control over bike fit and riding comfort. With a highly adjustable angle range, the HighSix allows you to quickly fine-tune handlebar height and reach—whether you’re chasing a more upright endurance position or a lower, more aerodynamic setup.
Designed around a durable 3D forged 6061-T6 aluminium construction, the HighSix combines strength, reliability, and adjustability in one clean package. It’s equally suited to commuting, trekking, MTB, touring, and e-bike applications.
Comfort When You Want It. Performance When You Need It.
The standout feature of the HighSix is its wide adjustable angle range (-30° to +40°), allowing riders to significantly alter cockpit height and riding posture.
Raise the stem angle for:

- Reduced lower back and neck pressure
- Better visibility and relaxed handling
Lower the angle for:
- A more aggressive riding position
