Sram Eagle users rejoice! Now you can enjoy the supreme shifting and performance of a Kolossos oversized rear derailleur with your Sram XX1 Eagle AXS rear derailleur. Our new Sram Eagle Kolossos works with all mechanical and AXS versions of XX1 Eagle, X01 Eagle and GX Eagle.

Kolossos is the Greek word for a statue, much larger than the original subject. Sounds appropriate for replacing your 12 and 14-tooth stock pulleys with a 18-tooth narrow-wide bottom and a 14-tooth top pulley, built on our stiffest Kolossos cage yet.

Kolossos cages are built for reduced friction with shifting accuracy and chain retention in mind; something near and dear to all XC, marathon and enduro riders.

Ground clearance is not a concern as overall length is within 2mm of your stock cage, but doesn’t hang lower. And, your Kolossos ships with our road seals for best efficiency, but can be swapped to cross seals for wet riding environments.
