Praxis M30 Press Fit bottom brackets are designed to be a proper bottom bracket (BB) for installing Turn M30 spindle based cranks in either; • BB30, • PF30, • BB86, • BB92 • Specialized’s OSBB frames. Our patent pending design keeps the cartridge bearings outboard of the frame right on Shimano™ spec for greater rigidity and free of frame/c-clip tolerance issues that other systems deal with.Simply press in the longer non-drive-cup, then the shorter drive cup threads into it. As the drive cup threads in, our trademark Collet system expands to a precise limit evenly dispersing pressure for a super tight fit. With both cups connected and our 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.
In the ever changing world of bottom bracket standards, Praxis aims to have a bottom bracket for pretty much any modern bike and crankset. The M30 Press Fit Bottom Bracket is suitable for Praxis Works M30 cranksets in a variety of bracket shells.Compatible with Praxis Works M30 cranksets with 30/28mm spindlesHighly durable Enduro bearings are designed to spin freely and last well in harsh conditionsForged & machined aluminium cups are highly durable and easy to fitBuilt around high-quality Enduro steel cartridge bearings and forged and machined aluminium cups, Praxis bottom brackets are built to be strong, durable and not afraid of harsh conditions. The quality sealing keeps grime away from the bearings, while the cups construction mean they can be easily transferred between frames with no fear of damaging them. If you want a dependable bottom bracket that is supremely reliable and easy to install, look no further.

Praxis Works Alba 1x10-11 Speed Direct Mount ChainsetDeep in the hills of Santa Cruz, cyclists are met by a nasty, four-mile, 1800 ft. climb named Alba Road. This respected ascent was the inspiration for the Praxis Works Alba road chainset. With its shapely forged-alloy arms, M30 alloy spindle, LevaTime II X-Spider and chainring, the Alba is ready for anything.LevaTime X-Spider and ChainringThis 1x10/11 speed chainset features a LevaTime II (LT2) X-Spider and chainring that's the product of years of relentless testing and tweaking. This all new LT2 X-Spider is even stiffer than the original generation X-Spider. With a new forging design to support the new LT2 5mm plate big rings, this direct mount model keeps things flex-free when it's time to put the power down.One Shot ForgingAt Praxis Works, the primary reason it forges its chainring is that it allows them to create dramatically shaped teeth and ramping surfaces. The brand's “One Shot” forging process allows it to make these shapes, and at the same time, create a harder and tougher ring than the competition's machined rings. Imagine for a second, you have a big hammer and you are hitting a cold block of metal trying to shape it. Now, imagine the hammer is the size of a car and when you swing that hammer you've got hundreds to thousands of tons of pressure behind it. It's a very intense and difficult process that requires a great deal of tooling know-how. This manufacturing process happens to be the brand's specialty.M24 Bottom BracketThis chainset comes complete with a press fit M24/GxP bottom bracket for installing a M24/GxP spindle crank into a BB86 Road or BB90/BB92 MTN Frame. Praxis M24 bottom brackets have a 24mm Drive and a 22mm NonDrive Bearing. These are specifically made for use with Praxis M24 spindle cranks or SRAM GxP spindle cranks. A drive-side wave washer is used for preload of the bearings.

Whether you re cyclo-crossing in mud or grinding gravel, Praxis 1X rings are ready for action with the Wave tooth profile. Licensed and developed in conjunction with Mountain Racing Products, the Wave profile applies alternating lateral force to each chain link to actively retain the chain to the ring going beyond narrow/wide implementations that rely solely on friction, while allowing room for mud, debris, and grit to escape. The Wave design also wears more slowly than competing designs by spreading the load over larger surface areas. Plus the 1X rings are machined from top quality plate 7075 T6 aluminium for superior stiffness and hard anodized to take a beating.PLEASE NOTE: Chainring bolts are NOT included.110 BCD7075-T6 AluminiumAvailable in 42t and 40t sizesWide/Narrow10 & 11 Speed compatibleMust be used with 'Clutch' type Rear Derailleur
