The Super B TB-CH15 Chain Keeper is a bike tool that holds your chain securely in place to prevent tangling and frame damage during cleaning, maintenance or transport. Its integrated pulley can be used independently on 12 mm thru-axle frames, and cleverly allows rear derailleur shifting while the tool and pulley remain installed, making it a genuinely useful addition to any home workshop or travel kit.
