Bolt Chain Adjuster Blocks (Yamaha)
Bolt's innovative Billet Aluminum Chain Adjuster Blocks hold 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. With these, your chain adjustments require only one 10mm wrench! Each anodized 6061 aluminum block has bright laser etched aligning marks. These permanent marks are spaced so they are easy to see making wheel alignment a snap! Fasteners have an anti-seize compound pre-applied to the threads.
