CeramicSpeed Eagle 14 Coated Pulley Wheels Black

.SRAM´s 1x Eagle component system has a 12-unit cassette.The developers at Ceramic Speed ??have built shift rollers that can handle the load better than the original.These CeramicSpeed ??shift rollers work with less resistance, which increases the power transmitted to the rear wheel and also increases the useful life, as they lengthen between replacement intervals.These pulleys are also compatible with the new SRAM Eagle AXS derailleur.The upper and lower pulleys have a narrow and wide tooth shape.Both pulleys have 14 teeth.The Ceramic Speed ??Shift Rollers are designed for competitive shifting performance and maximum drive efficiency thanks to their unique narrow-width design, which increases performance by 34.4%.Machined titanium discs have a service life three times longer than machined aluminum.Coated bearings reduce air resistance beyond standard bearings.The reduction is more than 50%.Coated raceways are 75% harder than hardened steel raceways and last 60% longer than standard be
