GMA Fat Lock-On Grips

Ergon GMA Fat Lock-On Grips are ergonomic, all-mountain mountain bike grips built for trail riders who want more control and less hand fatigue on long, rough descents. Targeted cushioning and defined grip zones improve comfort and damping where it matters, while a secure lock-on interface keeps the grips from twisting when conditions get wet or the riding gets rowdy.

• Defined grip zones with Gravity technologies - Improves friction and control for confident steering and braking input in mixed conditions

• Outer stop - Minimizes lateral hand slippage for more consistent grip security when the trail gets rough
