Work like a charm, even in 2X12

Every year now, there's less & less juice in my legs and even 9% grade longer than a few hundreds meter was a peine with 46-33. I did not want to switch to 1x so i wanted to try SRAM Red axs XPLR derailleur SRAM 12 speed XPLR 10-44T cassette which i ordered from Bike Tires Direct. After installing and fine tuning in my garage, next day i went out to try it. OMG, what a joy. It worked like a charm. Shifting so smooth that it's so hard to hear it. That 9% grade climb look like no grade at all now. So to be clear, after reading so much on internet, SRAM Red XPLR derailleur with XPLR 12 speeds 10-44T cassette for me work very good with 2x12, crank 46/33. So normal ride on the road 46 front and 10 rear. As the grade increase, down shifting all the way to 44 and if needed, down shit to small crank 33. Every thing work so good. I actually down shift to 33 crank when i am on 38 or even 32 on cassette.

Now at 78, I am not afraid anymore from the mountains of any grade. I have ordered 2 more of that cassettes (i have 2 road and mountain bike has 10-52).

Bike Tires Direct was and is like always, very helpful and friendly when you need it.
