The wait is over. An affordable 12 speed option has been released by SRAM! GX Eagle is exactly what riders looking to ride everywhere need, a 10-50 tooth 500% gear range will get you to the top of the tallest mountains out there. The cassette is only 100 grams heavier than the higher end Xo1 version and half the price! The entire group pictured will out take $470 out of your bank account and an even $400 if you already have a narrow wide chain ring. Not bad for a group that shifts about about the same as the higher end version!
