The best bash guide on the market! If you're running a 1x drive train on your long, low slack enduro bike, you will benefit from an OneUp bash guide. Designed to fit the standard ISCG05 mounts fitted to most enduro bike frames, the OneUp Bash Guide can be installed with one allen key and without the need to remove your cranks.

The top guide makes a huge difference to chain retention. Even if you're running a narrow wide chain ring and a clutch rear mech, a dropped chain can still happen, especially when the chain is getting toward the end of its life. For the small amount of weight (around 100g), the extra security is a must for racers. If you do somehow manage to dislodge your chain, the tool less top guide can be hinged to get the chain back on.

If you've ever hit your chain ring on a stump or fallen tree, you've probably felt the chain dig in and grip. The OneUp guide takes this resistance and grip away, in the same way as skateboard deck rails help the board slide along a ledge.

Three bash guards are included to suit different chain ring sizes from 28-36T, and you can replace the top guide with a choice of blue, green, orange, red, turquoise or purple.

If you never hit your chan ring off anything, we also stock a bashless ISCG05 chain guide. There's also an underbash kit which fits the Deviate Highlanders and Claymores if all you need is a bash guard.
