## Customer Reviews

### ⭐⭐⭐⭐⭐ Worth it.
*by K***Y on January 8, 2020*

Fast shipping from the seller.It does not come with the b-link but does include the mounting screw if you choose to use a goatlink.I used this set up as a 1x10 with an 11-40 cassette and goatlink. Works great. Extremely quite. Clutch system rocks. Huge upgrade.

### ⭐⭐⭐⭐⭐ Bargain buy for a perfect derailleur.
*by A***R on May 30, 2020*

My old XT SGS wouldn't upshift consistently. This new one works perfectly. My bike is not set up for direct mount so I used the mounting link from my old derailleur. No issues and saved 20+ dollars!

### ⭐⭐⭐⭐⭐ Xt is the best.
*by C***. on March 18, 2020*

The perfect upgrade to any mountain bike.
