Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Praxis Bottom Bracket 386 Evo for M30 Thru 30mm Spindle

Brand:Praxis Works

Code:PR-86-6101

M30 Thru BB

The Praxis M30 Thru BB is designed to be a proper bottom bracket (BB) for installing the Praxis Lyft Carbon Crank, RaceFace "Cinch", Rotor “REX” MTB Crank or CaneCreek eeWings. The Praxis patent pending design keeps the Enduro 6806 cartridge bearings outboard of the frame for greater rigidity and free of frame/c-clip tolerance issues that other systems deal with.

For Press Fit Options

Simply press in the longer non-drive-cup, then thread the shorter Drive cup into it. As the drive cup threads in, the 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.

  • For Praxis Lyft Carbon, RaceFace "Cinch", Rotor “REX” MTB Crank or CaneCreek eeWings.
