Customer Reviews
With it being such a challenge to find new bikes, upgrading my 5 year old Yeti SB6c with electronic shifting seemed like a good idea and now that I've got a few rides with the GX Eagle AXS I couldn't be happier! The installation was a snap although it took awhile to dial things in. The shifting is very sensitive to the B-screw adjustment and the jig that comes with the upgrade is great but it's definitely a 2 person job since the adjustment needs to be done under sag and you'll need a second pair of eyes to get it right! The SRAM set up video on YouTube is a great resource. On the trail, the shifting is fast and precise but it does take a bit of time to get the new "muscle memory" for how the AXS shifter works vs. the mechanical version. Overall, I'd say the upgrade was well worth it!
