Description
Mountain bike rear derailleur for double chainring Shimano 12V. SLX M7120SGS
After introducing 12 speed cassettes on its top of the line XTR groupset, Shimano extends it to the very popular Deore XT and SLX groupsets. However, this is not the only change and it is indeed two brand new groupsets that the Japanese brand has just introduced. The rear derailleur will be available in two versions, for single or double chainring. The length of the clevis does not change but the angle to the frame is different. They are perfectly identical in all the rest of their design and both use 13 teeth rollers mounted on bearings.
