Shimano Deore XT DYNA SYS

High-precision derailleur with 30 gears. You need fewer front shifts as a result of the larger width on the cassette. Thanks to the new 42-32-24 chain grades for 3x10, there are fewer crossovers and therefore more usable gears. Default operation via Shimano Rapid Fire switch handle.
