Praxis continues to expand its continually growing range of drivetrain offerings for 2016, now with a wealth of new chainring sizes, more value-priced cold-forged alloy cranks, and additional bottom bracket fitments that promise to make your next ride creak-free.
Headlining the collection of chainrings are new 1x-specific options for the latest Shimano XT and XTR asymmetrical four-arm cranks (96mm BCD). Each of the new chainrings will attach using existing hardware so the stock aesthetics will essentially carry over. Praxis will start with 30-, 32-, and 34-tooth sizes, with 36T and 38T sizes to follow.
We’ve been impressed so far with praxis’s narrow/wide tooth profiles, which have proven to reliably hold on to the chain even in rough conditions: we’ve been impressed so far with praxis’s narrow/wide tooth profiles, which have proven to reliably hold on to the chain even in rough conditions

Although Praxis made its name on the longevity of its cold forged conventional road and mountain bike chainrings, these new 1x-specific options – like most of the company’s other narrow/wide-profile chainrings (and nearly all narrow/wide chainrings currently on the market, in fact) – are CNC-machined instead.

If you’re specifically seeking drivetrain longevity, however, Praxis also offers a new cold-forged 4130 chromoly steel narrow/wide chainring. These will be heavier than equivalent alloy pieces, of course, but Praxis says they’ll last at least two- or three-fold longer, while a nickel coating keeps corrosion at bay. Praxis will start with just a 32-tooth option (four-arm, 104mm BCD) for now but additional sizes are pending.

Other new chainrings coming down the pike are direct-mount 1x chainrings for SRAM GXP crankarms and new road double chainrings for the latest SRAM Red crankarms.
Fresh new cranksets
Supplementing the well-received Girder hollow forged alloy mountain bike cranks is the new solid forged Cadet crankset for riders on tighter budgets. Praxis intends for the Cadet to go head to head with the Race Face Turbine in terms of stiffness and weight, but at a slightly lower price. Both single-ring and double chainring fitments will be offered.

Praxis is adding new solid-forged cranksets to its product range, which will cost quite a bit less than its hollow-forged ones with minimal performance penalty
On the road side, Praxis is getting into the 1x game with the new Zayante Sprint, which uses the same hollow forged alloy arms as the standard Zayante but with an enormous 160mm BCD four-arm spider made specifically to work with dedicated Praxis narrow/wide chainrings. Praxis will offer the Zayante Sprint with 48T, 50T, or 52T chainrings to start.
More creak-free bottom brackets
Praxis can largely be credited for finally solving the riddle of press-fit bottom bracket creaking courtesy of a thread-together cup design and a unique expanding centre section.

Whereas the original version was limited to conventional 24mm-diameter spindles in BB30 and PF30 frames, Praxis is now expanding the concept to cranks with long-format 30mm-diameter spindles (such as FSA BB386/392 EVO, Race Face Cinch, Rotor UBB30, and others).

The new M30 Thru bottom bracket uses the same expanding collet design as the original Praxis conversion bottom bracket for what should be a creak-free design
