Wethepeople Turmoil Sprocket

To ensure smooth running and solid-feeling drive, get a good quality sprocket, chain and driver set-up: the Turmoil sprocket is made from tougher 7075 alloy, full CNC machined, comes with a hard-anodised finish for an overall longer-lasting set-up. It comes with adapters for 19mm and 22mm crank axles since the hole fits 23.8mm cranks, and also comes in a spline-drive version (£54.99).
