Campagnolo 11-speed rear derailleurs work better with our pulleys, which are a marked improvement over stock. Ours reduce frictional drag and increase bearing life. Less drag means more power transmitted to the rear wheel.
There are three options. First is machined aluminum pulleys with our stock CeramicSpeed Balls installed in our hardened-steel races. This is our Standard Bearings. These test better than anything else on the market. Second, machined titanium pulleys with our Standard Bearings. Third is machined titanium pulleys with our ceramic balls installed in coated, hardened-steel races. Our Coated Bearings.
These are compatible with all 11-speed Campagnolo derailleurs, mechanical and electronic.
In the box:
2 x 11-tooth pulley wheels
4 x spacers
CeramicSpeed Bearing Oil in 15ml dropper bottle
The machined titanium pulleys last three times longer than those made of machined aluminum.
The Coated Bearings have races 75% harder than our hardened-steel races. They last 60% longer than our standard bearings. Drag is decreased by over 50% compared to our standard bearings.
There are different upper and lower pulleys, are marked as such, and have directional arrows etched on them.
The kits come with CeramicSpeed oil in a 15ml dropper bottle. The bearings come with oil in them already. The oil is to keep them running smoothly.
