OneUp Jackson Goldstone Lock-On MTB Grips

The offset profile puts extra rubber material on the top section of the grip where your palm rests most heavily. This design adds cushioning and vibration damping exactly where you need it most for long, aggressive rides.

Because of the raised palm pad, finger ridges, and diagonal thumb ribs, these feel more 'shaped' than a traditional round grip. They are designed to lock your hand into a specific position, which helps reduce hand fatigue and improves control on technical terrain.

The diameter ranges from 29mm to 33mm depending on where you measure. While they are designed for ergonomic comfort, riders with very small hands might find the 33mm section a bit bulky, though the tapered profile helps mitigate this.

It uses two different rubber densities to balance comfort and longevity. The 20A rubber on the body is soft and tacky for maximum grip, while the 45A rubber on the flange is firmer to resist tearing and wear from trail abuse.

You only need a 3mm hex key to tighten the single inner clamp. It is a straightforward lock-on installation that keeps the grips securely in place without twisting.

The core cutout removes material from the inner sleeve to create a small air pocket or softer zone under your thumb. This provides extra damping to help absorb trail chatter and impacts before they reach your hands.
