Designed to increase drivetrain efficiency, the oversized Gen 2 Pulley Sets will replace your jockey wheels to lower the friction and make the most of your wattage, giving you higher speeds with less effort.

The reduction in friction is driven partly by the large tooth count of the cogs, which cuts back on power loss through reduced articulation of the chain with each revolution of the pedals, improving efficiency and power transfer.

It's also driven by Kogel's performance bearings, which roll smoothly and support precise, consistent shifting, helping you to maintain a constant speed, even when the terrain gets bumpy.

Choose from hybrid ceramic bearings, for minimum friction and maximum durability, or full ceramic for a smooth ride, the lowest possible friction and the longest life, even in the harshest conditions and on the most technical terrain.

Stronger and longer lasting than standard plastic pulleys, the Gen 2 Pulley Sets are crafted from high strength 7075 aluminium and come with a choice of road or cross seals, to cut down on drag or protect the pulleys from water, dirt and dust ingress respectively. With their stiff aluminium cogs, they will translate every watt you produce into speed, giving you an edge in every race or training session.
