praxis wide rane mountain bike cassette

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.

XTR9000 rhythm step cassette is the way to go. ratios are perfect at keeping you at the right cadence. probably the best component of the group.

No compromises? Uneven gear spacing is a compromise. Praxis makes good stuff but this cassette is not well done.

This goes right to the top of the list for when I wear out my XX cassette.

@Pete, XTR9000 is 11 speed and twice the price. This is 10 speed but same gear range, same weight as XTR and I don’t have to upgrade my derailleur, or chain to install.
Seems like the way to go to me…

Those 6 tooth 28-34-40 jumps are pretty steep and abrupt. We’ll see… Love the rhythm step and it’s a significant improvement.

@pete I find the jump from my 36T to my 42T expander is totally fine. Seems be less of an issue at the low end.

Rode mine this morning with my 24-38 crank. it replaced an XT cassette with a General Lee extender. No complaints. It worked just fine and was a fair bit cheaper than my old combo.

Doh! just missed this. Ended up going with a One-Up 40t on my XT cassette. Nice product though Praxis!

Been riding mine since late last week and love it so far. Mine weighed in at 311g according to my buddies FEEDBACK scale. The rhythm based steps in gearing is really well put together and you feel like a gear lower than normal is just the right sweet spot for most of my climbing. Really the 40t is nothing more than a bailout gear for me and has just enough gearing ratio to make those few steep or long climbs that much easier. Not a HUGE increase in anything but definitely makes things a bit easier. This is on a SRAM X0 Type 2 RD with Shimano SLX crank with Hope 32t NW ring.

Seems like a lot of people are concerned with the jump from 34t to 40t but really it does not feel any different than a normal 11/36 setup. No special adjustments were needed other than slight tuning of the shifter, no B-screw adjustments or H/L limit adjustments were needed on my mid-cage rd.

So far, only 3 rides now, it has been a good investment and for those building new bikes or needing a new cassette I would definitely look at this for the price. Ultimately with the price of an expander ring, RadR cage (for shimano) and 16t to replace the 15t/17t you are looking a close to the cost, if not more than, of one of these cassettes.

Oh and definitely throw a new chain on.
