CYCLAMI Universal 18T Oversized Pulley Wheels – With Ceramic Bearings

With the Cyclami 18T, you get one of the most brilliant and affordable upgrades for your road bike or gravel bike. This 18-tooth oversized pulley wheel is designed with an innovative eccentric (offset) and hollow design that revolutionizes the way you optimize your shifting.

Thanks to the eccentric mounting hole, the wheel perfectly takes up extra chain slack. This means you can expand your gear ratio (run a larger cassette for steep mountains) and significantly reduce chain resistance – all without having to invest in a complete, expensive, and cumbersome derailleur cage system.

The benefits of the Cyclami 18T – Why upgrade?

• At the heart of the wheel are ceramic bearings, which roll significantly smoother than traditional steel bearings. This means fewer wasted watts when you are riding in an echelon or digging deep on the climbs.

• The large 18-tooth design ensures that the chain does not have to bend at such sharp angles as it passes through the rear derailleur. Less mechanical resistance gives you more speed for the same amount of power input.

• The large, hollow design doesn't just look super sleek on the bike; it also leaves room for a larger and more stable bearing. Thanks to the eccentric (offset) center, you maintain crisp and reliable shifting, even under maximum load.

• The teeth are designed to be extra deep, ensuring that the chain stays firmly in place. You avoid annoying "chain drops" and instead get a direct, immediate response with every single click of the shifter.

• Featherlight and rock-solid CNC aluminum: The wheel is milled from a single piece of lightweight aluminum. With a competition weight of only approx. 30-36 grams, you get maximum stiffness and durability without adding unnecessary weight to your bike.
