For this season I finally swapped my 2014 ICT's 2by with a sram eagle gx 10-52. It rides great and I managed to trip and land on the bike, derailleur to the ground (oops) - it is still good but it chatted a little in a couple of gears. I will adjust it if it gets an worse.
My second bike 2014 Beargrease is also undergoing a drivetrain change. I changed the bottom bracket and added a sram xx1 crankset and I am currently waiting for the arrival of xx1 cassette, shifter and derailleur that I ordered a week ago.
