The Kogel Preload Adjuster is a precision grade bit of kit that will take up any slack between your crank arms and your bottom bracket, to ensure your bottom bracket won't creak or prematurely wear out. Unlike stock plastic adjusters, it will remain in one piece with frequent use.
Made to work with 30mm and DUB crank spindles, and including a spacer and thread rings made from light aluminium, alongside a titanium fastening bolt, it sits inside your left crank and can be customised in your favourite colour to match the rest of your components.
