Tension and guide pulley set CeramicSpeed for SRAM 11s 1X Force 1, Rival 1,XX1, X01, CX1 off-road Alloy 626 stainless steel blac

SRAM’s 1x 11-speed rear derailleurs work better with our 12-tooth pulleys. They work with less mechanical friction, adding to the power transmitted to the rear wheel. They also possess greater durability, going longer between replacement intervals. CeramicSpeed Standard Ceramic Bearings - low friction, high durabilityBearing race material: hardened-steelCompatible with all 11-speed SRAM derailleurs: Force CX1, Force 1, Rival 1, XX1 MTB, X01 MTBPulley material: aluminiumBearing type: 626In the box:2 x 12-tooth pulley wheelsCeramicSpeed Oil for Pulley Wheel Bearings, 15ml dropper bottleCeramicSpeed All Round GreaseSticker sheetRELATED TECHNICAL INFORMATION:CeramicSpeed Standard Ceramic Bearings - put more of your energy into forward motion by reducing frictional drag wherever you can. 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.There are different upper and lower pulleys, are marked, and have directional arrows. These pulleys need to be installed with stock SRAM pulley spacers between the cages. Save those before installing CeramicSpeed.
