If you’ve been waiting for an all-in-one solution to giving your mountain bike a proper wide range cassette, Praxis’ unit is now shipping.
Unveiled in March, the cassette runs from 11 to 40 teeth in smoothly staggered increments, providing more consistent cadence across gear shifts. By limiting the upper cog to 40 teeth, they say it’ll work with modern mid- and long cage rear derailleurs without much B-Screw adjustment. And, it’ll wotk for both 1x and 2x drivetrains.
Claimed weight is 320g and retail is $129. Check out the full tech specs and hands on photos here.
