Better known for their bottom bracket solutions and aluminum (and now carbon) cranks, Praxis is entering the wheel world with both carbon and aluminum models. The former is their $1,799 USD C32 wheelset that's been in the works for a few years now, and one that Praxis has put together with maintenance and ease of use in mind. That means that it's assembled with standard J-bend spokes (four extra included), external nipples, comes pre-taped and is built with a set of Praxis' own hubs that employ DT Swiss' internals for simple maintenance and compatibility with all axles and drivers.

• 3mm offset assymetrical rim
• Hookless bead w/ bead lock shape
• J-bend spokes, external nipples
• Weight: 27.5'' - 1,628g, 29'' - 1,726g
• Availability: late June
• MSRP: $1,799 USD
The rim bed requires a wrap of tubeless tape to seal because the nipple holes are drilled right through, but this means that it should be easy to swap out a damaged nipple when required. And just like most carbon rims out there, the C32 has a hookless bead design, as well as a bead lock shape to the bed and sidewall that should help to increase strength and make it quick to seal up tires.
Praxis won't sell bare C32 rims - they want to own the build process themselves - but they do plan on offering a no questions asked, $300 USD crash replacement for non-warranty issues.
Praxis wanted a set of reliable and ultra-compatible hubs at the center of their C32 wheelset, but they also were looking for something different than just an off the shelf hubset. That lead them to design their own hub shells but drop in internals from DT Swiss. They went with the company's 36-tooth Star Ratchet system rather than the higher tooth option because it's proven to be more reliable, although riders can install their own 54-tooth Star Ratchet kit if they want quicker engagement. There are both Shimano and SRAM compatible driver options, of course.
Praxis has done something unusual up front: radial lacing on the non-disc side. Haverstock says that testing revealed that the radial lacing on one side resulted in a more torsionally rigid package, but that hub manufacturers generally don't want to go down this road due to the extra stress it puts on the hub flange. Good thing Praxis has their own hub shells - the flange that sees the outboard, radial lacing is thicker and stronger than you'd see on a standard hub.
