The XG-1150 Full Pin Cassette by Sram allows everyone to enjoy the benefits of 11 speed. The cassette is made using 11 individual steel rings, which are held together using high strength steel pins, under Sram's new Full Pin Technology. This also increases the mud clearance in the cassette which means that shifting is more accurate. The cassette is coated with the JET finish which provides a higher level of corrosion resistance so your cassette will look cleaner for longer. 11-speed GX MTB cassette SRAM XD - for SRAM XD type freehubs 10-42t Ratio Compatible with all SRAM 11-speed MTB groups
