AbsoluteBlack's revolutionary Oval Bash Guide is here. This is the only bash guide on the market that is designed specifically for oval chainrings, keeping your chain secure at every single crank position.
Our Oval Bash Guide™ can accommodate any chainline between 48-53mm. The chainline is adjustable in 0.5mm increments, with 4 included spacers (0.5, 1, 2 and 3.5mm).
TOOL FREE - FRONT FLIP TECHNOLOGY
Our bash guide has a tool free movable front part of the cage. You can access the chain using your hands only. If you ever need to make small adjustments on the trail after a crash or a broken chain, you don't have to worry about removing the bash guide. You simply flip the outer section of the guide with your fingers, which will give you free access to the chain. Once you’ve made the adjustments, you flip it back.
Our chain guide can accept oval chainrings from 26-34T and round rings from 28-36T. Small markers on the side of the back-plate show the ideal position of the guide for your desired chainring size.
