The Shimano SLX rear derailleur features direct cable routing and low profile Shadow technology so it is even sleeker than in years past, and since there is no contact with the chainstay your pretty frame will have fewer nicks and scratches. A stronger guide spring adds crispness, and lighter materials shave this new version down to only 260 grams.FEATURES 10-Speed compatibility Consistent shifting performance Low profile Shorter pulley cage Direct cable routing No chain stay contact
