Bolt's innovative Billet Aluminum Chain Adjuster Blocks holds your wheel precisely in place while you tighten your chain. The unique design features an integrated bolt slot so your blocks stay in position even when the axle is removed. This makes for a quick and easy chain adjustment as you only need one 10mm wrench! Each anodized 6061 aluminum block has bright and easy to see laser etched aligning marks. These aligning marks are placed so that only one mark engages at a time making aligning a snap! The fasteners even have an anti-seize compound pre-applied to the threads.
