The CeramicSpeed OSPW System for Shimano is developed for performance optimisation and the watt savings start at 2.4 watt.
This plug-and-play product is the result of an in-depth development process and has been designed for optimal performance. Created to answer the needs for less friction - as much as 60 %, increased speed and a more efficient drivetrain. This OSPW System is the true advantage that helps you to comfortably ride any distance.
Like all other products delivered by CeramicSpeed, this product has also undergone a thoroughly test program. CeramicSpeed is proud to say that professional triathletes like Tim Don and Tyler Butterfield are amazed of the new pulley wheels system and have a great feedback for the product.
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.
It is important that you properly lubricate your bearings in order to ensure optimal performance and maximum longevity. Add oil to the outside of the bearing seal, so that oil can penetrate the bearing. Do this when you lubricate your chain, or if you have washed your bike or have been riding in wet or muddy conditions.
