“It's a very good upgrade from a Eagle SX Derailleur and easy enough to fit particularly after watching a very informative Youtube instructional Video. Much smoother shifting. Good price from 99bikes and reasonable shipping times.”
“Just removed the SX shifter from my Trek Marlin 8, if you're thinking about it, DO IT! it's night and day difference. I'd advise changing the shifter too... The same Cassette, Cranks and chain can be used but id suggests getting a better chain too. Very impressed with this product. Works amazing”
“Very good upgrade from SX Eagle. Very worth it. Clutch and shifting are a lot better. Definitely would recommend to anyone looking to upgrade or replace their SX or NX. Go for GX for the $30 extra than NX to get improved shifting and a much better clutch.
Chose GX over X01 because it's almost twice as expensive.”
