Review on 🚲 Deore XT Rear Derailleur, 11-Speed, Black: Optimize Your Bike's Gear Shifting Performance by Shane Mack

not the latest but i didnt want more cogs anyway so for what i need it came at an affordable price. xt is as good as it gets for me. xtr costs more and the weight difference is small. You need a shifter (be careful as there are two types, the one that mounts to shimano brakes and one that doesn't fit and a couse xt 11 speed cassette that fits better performance. If you have money need to save, choose SLX speeds 11) Cassette as it is a great replacement
