Troubleshooting

Tool does not fit securely in the dropouts

Ensure you are using the correct end of the tool for your frame's spacing (135, 142, 148, or 150mm). Verify that your frame uses a thru-axle and not a quick-release skewer.

Chain slips off during use

Ensure the chain is correctly routed over the chain keeper tool. Double-check that the tool is seated properly in the dropouts and the chain is under appropriate tension.

Difficulty inserting the tool

Confirm that there are no obstructions in the frame's thru-axle slots. Ensure you are aligned correctly with the frame's interface.

Setup, Compatibility & Care

Setup: To set up the tool, remove your bike's rear wheel. Insert the chain keeper tool into your frame's rear dropout, ensuring it engages securely with the thru-axle interface. The tool is designed to replicate the spacing of your hub, so select the correct end for your frame's width (135mm, 142mm, 148mm Boost, or 150mm).

Compatibility: This tool is specifically designed for bicycles utilizing a thru-axle system. It is compatible with frame spacing of 135mm, 142mm, 148mm (Boost), and 150mm. For bikes with standard 9mm quick-release (QR) axles, the Laser Part No. 8199 is required.

Care: After use, wipe the tool clean with a dry or slightly damp cloth to remove dirt and grease. Store it in a dry place. Avoid using harsh solvents that could damage the material.
