OneUp Bash Guide
Another quality item from OneUp with clean construction . The fitment of the chain guide is great with the shims provided and has 3 different size bash guards for different size chainrings. Like everything OneUp a lot of thought has gone into it.

Very well engineered, top quality kit. Looks good too. My only issue was that when fitting, I needed to use some washers, the spacers supplied were too thick and I couldn’t fit without packing it out slightly.

Nice kit, especially with different guards for different chainring sizes. A tiny bit fiddly to mount on my bike, but was still able to do this without removing cranks which was a win!
