Looking for an upgrade to your Campagnolo 12-speed group? C-Bear has just announced their new 12-speed compatible derailleur pulley wheels, available with either hybrid ceramic (€79) or full ceramic (€169) bearing options. They made their official debut at the Tour Down Under on Lotto Soudal’s team bikes, as shown in the photo above from a team mechanic.

C-Bear ceramic derailleur pulley wheels for Campagnolo 12-speed rear derailleurs

The 12-tooth pulley wheels are made of Delrin, same as most stock pulleys. The differences between them are the bearings, both options being an upgrade over stock. The hybrid ceramic uses ceramic balls with steel races, and the full ceramic puts a ceramic race in there for the absolute minimum friction. Available in February.

I use C-bear full ceramic 11T for Campagnolo Record Titanium 10 speed with full satisfaction. No lube, spins free for 18 seconds after approx 1000 miles of use. Although upper pulley has no lateral play as in the original part, shifting performance is not affected. 11T fits into the place of 10T original pulley givig a cooler look and possible friction benefit:)
