The CeramicSpeed Pulley Wheels for Shimano XT/XTR offers a unique sy mmetrical 14-tooth narrow-wide design that provides exceptional shift performance. The narrow-wide design delivers precise engagement of the chain, both on and off the pulley wheels. The increased pulley size, compared to stock, reduces chain friction. The pulleys have a lightweight machined alloy body for durability and long life, and are developed, designed and handbuilt in Denmark.

CeramicSpeed balls are 100% smoother and 15% harder than ceramic competition. The bearings last at least 3x longer than other bearings. All Round Grease - Designed to suit the maintenance of CeramicSpeed Bearings, the CeramicSpeed All-Round Grease maximizes your bearings’ lifetime and performance. This type of grease is a low to medium viscosity lubricant and works as the best compromise between friction influence and lifetime. We recommend it for optimal use in dry and sunny weather conditions, where no or very little contamination threatens the bearing. The application covers mostly road riding conditions, however it can be used off-road in the same weather settings, on all types of CeramicSpeed Bearings. When lubricating your bearings, we recommend a fill rate of 60-80%.Maintenance:Depending on the riding conditions it is recommended once a year to re-grease your CeramicSpeed Bearings.If used in very wet or muddy conditions, maintenance might be required more often.If high pressure washer is used, please do not point jet stream to any of bearings (headset, bottom bracket, wheel hub, full suspension links) as it may wash out the grease. The kits come with CeramicSpeed oil in a 15ml dropper bottle. The bearings come with oil in them already. The oil is to keep them running smoothly.
