It's kind of a big deal.

Designed, developed, and produced in Denmark by Ceramic Speed, the Oversized Pulley Wheel (OSPW) System for SRAM Mechanical derailleurs deliver an efficiency-enhancing competitive advantage. With its unique design, the OSPW offers efficiency savings starting at 40% over the stock SRAM derailleur pulley wheels.

This specific version of the OSPW is designed for SRAM's mechanical derailleurs, and as such is only compatible with the following SRAM 10/11-speed derailleurs: Red, Force, Rival, and Apex.

The Ceramic Speed OSPW for SRAM 10/11 speed derailleurs includes two oversized 17-tooth aluminum pulley wheels housed in a robust polyamide and carbon fiber cage, oil, and a Ceramic Speed sticker sheet.

MAIN QUESTION is will you benefit from this pricey upgrade? Short answer yes.

Long answer is this upgrade is most likely the last upgrade for your superbike. If you have already, for example, upgraded your wheelset, your cassette, your derailleurs, your crankset/bottom bracket, your cycling shoes or maybe even your chain, and you still have funds left over then go for it. CeramicSpeed products are there to minimize the hidden force of friction that you cant see; minimizing frictiion is beneficial because your pedaling efficiency is maximized since more of your hard earned watts are transferred from legs to bicycle. This results in going faster with lesser effort than you would if friction was not minimized.

May not be the upgrade for everyone, so do take into consideration what your bike needs first. If everything else has been optimized and dialed in, then the OSPW system makes sense as it will squeeze out those last precious watts, which in turn should make you faster and more efficient on your superbike.
