Nukeproof Horizon Race Handlebar GripsNukeproof developed their Horizon Race Handlebar Grips in collaboration with their top downhill and enduro pro riders. By using their expert input, Nukeproof has created grips with superior vibration damping, comfort, and grip in all weather conditions.

So, whether you prefer to ride with or without gloves, you'll enjoy consistent and comfortable grip no matter how hard you're pushing yourself!Locked on and SupportiveWith lockrings on either end, these grips are going nowhere. Even as you throw yourself into the berms and land the biggest jumps, they'll maintain a secure connection with the bar.

Nukeproof Sam Hill Enduro Race Super Soft GripsFollowing on from the success of the Nukeproof A15 durometer Sam Hill Series Grips, which Sam rode to overall EWS victory in 2017, Sam asked Nukeproof to develop an even softer compound for long days on the bike riding the toughest Enduro stages in the world.Perfect for Enduro Racing Extra Soft CompoundSam has always been particular about his setup and Nukeproof has taken great pride in developing no nonsense, custom products for Sam with some innovation even coming from his motocross bike! Together, they have helped to produce World level products that everyone can use. These grips were first used by Sam in round 4 of the 2018 EWS where he took the win and has been using them ever since. After that race he described the compound as “extra extra soft, semi throttle durometer” and described the grips as “pretty comfortable little things”.
