CeramicSpeed has a knack for outrageously priced derailleur pulleys. Earlier this year, they unveiled their lighter, but more importantly more durable, 3D printed titanium pulleys for Shimano derailleurs. The wheels use an oversized design (OSPW) with 13 and 19t, and utilizes 3D printing to create a hollow pulley wheel that ends up about 10g lighter than aluminum but with twice the life span. The set includes a carbon reinforced PA (Polyamide) derailleur cage with three sing settings designed to fit the oversized wheels, and it’s meant for up to 32t cassettes. Even with twice the durability of their aluminum pulleys (which are more durable than stock), you’re still paying a premium with a $1,700 price tag.
Fortunately, you can get many of the same benefits for just $499/$599 for the uncoated and coated aluminum versions. Using the same 13t upper and 19t lower OSPW design, the wheels are CNC machined and available in black and red – both in coated and uncoated bearing races with the coated products claiming an even longer life span.
CeramicSpeed claims any of their OSPW cages reduce friction by 40% compared to the stock Campagnolo wheels and cages, and are up to 3-5x more durable. All three versions are compatible with Campagnolo Record mechanical, Record EPS, Super Record mechanical, Super Record EPS, and Potenza mechanical derailleurs.
