So in my humble opinion the best shifter of all time has to be the Shimano Thumbshifter either the Deore SL-MT60 or XT SL-M730/2/5 varients , however I’m interested to know how many of you out there use Sachs/Sram ESP grip shift shifters and accompanying derailleurs, and also for those not using them , have you ever tried them ? do you like or dislike them ? I’d love to hear your feedback
