As the drive cup threads in, the Praxis trademark Collet system expands to a precise limit evenly dispersing pressure for a super tight fit. With both cups connected and the collet set exactly to spec, there is no chance the bearings can come out of alignment or wiggle/walk out of the frame. This design also uses a compressible o-ring on the non-drive side cup to compensate for frame shell width discrepancies.

Named after a famous redwood-covered climb in Santa Cruz, California, the Praxis Works Zayante Carbon M30 DM crankset is the ultimate blend of lightweight and stiffness, with rigid carbon arms and versatile chainring system, this is the ultimate carbon crankset for road, gravel or CX use.Lightweight carbon arms are incredibly stiff for efficient power transferM30 spindle is compatible with BSA, BB86, 386EVO, BB30, PF30, T47, BBRight & OSBB bottom bracket shells BB's sold separately10/11spd LevaTime X-Ring chainrings are cold forged for supreme shift quality & durabilityVersatile modular design can accept 2x or 1x DM chainringsLightweight at just 615g (172.5mm w/ 50/34T Chainrings)Where most cranksets can only be fitted with a small selection of chainrings, the Zayante Carbon is designed with versatility in mind. While equipped with 2x chainrings as standard, the direct mount design can easily be swapped out for a 1x chainring or another 2x combination in a different ratio. Praxis wants you to have control. Add in to this compatibility with pretty much any bottom bracket shell on the market when used with the appropriate bottom bracket, and you have an incredibly versatile crankset that is happy to grace lightweight carbon race bikes or tough gravel bikes. The crank arms themselves are carbon, which gives them immense strength and stiffness, so you can be sure every watt of power your legs can muster isn't wasted with flex. Despite this, the crankset is extremely light at just 615g. The M30 spindle also helps to keep weight low and stiffness high.Whereas most chainrings are stamped or machined pieces of aluminium, the Zayante Carbon's X-Ring chainrings are cold forged from 7075 T6 aluminium and then hard anodised. This unique method creates chainrings that are just as light, but are much, much harder wearing and provide slicker shifting for longer. Further improving the shifting performance is Praxis Works LevaTime Shifting Technology. LevaTime Shifting boasts a series of synchronised ramps and strategically placed shift pins to help deliver perfecting every time. Lightweight, stiff, smooth shifting and extremely versatile, the Praxis Works Zayante Carbon M30 DM crankset is perfect for riders who want maximum performance without breaking the bank.
The Axe30 M30 bottom bracket bearings are specifically designed for use with a 30mm axle and DMR's Axe cranks on a frame with a PF86/92 bottom bracket shell.
The Northern California Coast and Santa Cruz Mountains are steeped in road riding history. To honour it, Praxis Works named its new top-level crank Zayante, after the fabled redwood-covered climb that's a secret training ground for many local pros. The Zayante Carbon is the ultimate marriage of lightness, stiffness and versatility. Carbon Fibre Road Chainset Made exclusively in Praxis Works' own carbon lab, the Zayante is a homegrown product from start to finish. From initial napkin sketches, to rapid prototyping, revision after revision, exhaustive testing and certification for production. Developed and made in-house with the brand's hybrid "RTM+Filimant Winding" manufacturing methods, everything is done by a dedicated team. LevaTime X-Spider and X-Rings With its elegant and shapely carbon arms the Zayante is in a class of its own. This past year Praxis Works went further and updated it with its LevaTime X-Spider and X-rings. Now weighing in at a feathery 620 grams the Zayante Carbon has improved on its already solid reputation as the go-to crank carbon crank for riders globally. Please note: A bottom bracket is not included with this chainset but is available separately. This chainset is compatible with a Praxis Works M30 BB86 bottom bracket. Praxis M30 bottom brackets have a 30mm Drive and a 28mm NonDrive Bearing. These are specifically made for use with Praxis M30 spindle cranks. A drive-side wave washer is used for preload of the bearings. Born and based in the cycling mecca of Santa Cruz, California, Praxis creates and manufactures some of the best bicycle parts on the globe.
