Description of absoluteBLACK Oval Guide S3 / E-Type Chainguide

The absoluteBLACK Oval Guide secures the chain movement at every single crank position even if oval chainrings are used. Its adjustable chainline from 48 to 53 mm makes it compatible with every single bike setup. The chainguide is compatible to any 1x10, 1x11 or 1x12 drivetrain with absoluteBLACK oval or round chainrings. Fits to SRAM S3, Shimano E-type and E2. The mounting points must be attached to the main frame.

For extra insurance

While absoluteBLACK's oval chainrings with their own patent pending narrow/wide teeth profiles don't require any chain retention to keep the chain firmly in its correct position, there are still riders who feel safer with some form of backup and extra insurance that their chain will remain securely located. If you ride in demanding terrain, love rock gardens and jumps, or simply want to feel extra safe, the Oval Guide is the right solution. It is extremely light, small and easy to mount. It is designed to guarantee chain retention, but at the same time made to be almost invisible.

Features absoluteBLACK Oval Guide S3 / E-Type

Adjustable Chainline
The Oval Guide chainguide can accommodate any chainline between 48 and 53 mm. That means it fits from 1X setup with 49 mm chainline to Boost specific 52 mm chainline and more. The chainline is adjustable in 0.5 mm increments with help of the 4 included spacers (0.5, 1, 2 and 3.5 mm).

Tool Free Front Flip Technology
absoluteBLACK's chainguide 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 broken chain, you don't have to worry about removing the Oval 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 adjustments, you flip it back.

Adjustable Size
The Oval Guide can accept oval chainrings from 26 to 34 teeth and round rings from 28 to 36 teeth. Small markers on the side of the back-plate show the ideal position of the chainguide for your desired chainring size.
