Paul Components Chain Keeper (Black) (35mm)

The Paul Components Chain Keeper is a guide to keep your chain right where it belongs. Mounted in place of a front derailleur, the Chain Keeper works with single chain ring drivetrains using a narrow chain. The chain block surrounds the chain as it meets the chainring and prevents it from skipping off. The Chain Keeper clamps onto the seattube of the frame. The portion of the seattube where the clamp mounts must have a circular profile and match the selected diameter. Designed with adjustability in mind, the Chain Keeper can accommodate a range of chainline measurements and chainring sizes. For frames with tapered seattubes, the Chain Keeper Extension can be used to raise the clamp to a higher section of tubing with a straight circular profile. The Extension can also be used on some rear-suspension frames to reposition the clamp behind the seat tube. (sold seperately) Note: This product is not designed for downhill, freeride, or big hit use. Specifications: Material: 6061 Aluminum Finish: Anodized Color: Black Weight: 69g
