Reliability and precise shifting is what we have come to expect from SRAM twist shifters. The XO shifters have a loyal following and are attractive to riders that want an alternative to trigger shifters for a high-end bike.
There are plenty of riders on our staff riding Twist Shifters and we have noticed a phenomenon - most folks that do not like this style of shifter have never actually used it. Thanks to a lot of engineering from SRAM, they work great and the shifting is incredibly precise. They are definetly worth a try.
