Developed and designed entirely by CeramicSpeed the Oversized Pulley Wheel System for Campagnolo is advanced for the optimization of bike performance. Everything from bearings to the cage is made from the highest quality materials. The oversized aluminium pulley wheels are fitted with standard or coated CeramicSpeed Bearings, which reduce friction to the minimum.
The 13/19-tooth OSPW for Campagnolo privides a 40% lower friction over a standard 11-tooth Campagnolo pulley wheel and fits up to a 32-tooth cassette.
The OSPW for Campagnolo is compatible with all Campagnolo electronic rear dereailleur (EPS) and all rear dereailleur with a mounting sleeve – no matter the age and model.

IMPORTANT: When travelling, please remember to dismount your entire rear derailleur with an Allen key, as the OSPW System will not fit in most bike travel bags and could be damaged if left on.
For correct mounting of the product, please find a manual and video here.
Regarding the maintenance of your OSPW System, it is important that you properly lubricate your bearings in order to ensure optimal performance and maximum longevity. Add oil by using the lubrication points on the back cage plate, so that oil can penetrate the bearing. Do this when you lubricate your chain, if you have washed your bike or after riding in wet or muddy conditions.
