Product Description

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.

Occasionally, without notice, manufacturers change product design and/or specifications.

Bottom Brackets Guide

What is a bottom bracket?

A bottom bracket is the bearings that the crank axle passes through, keeping the cranks turning smoothly.

Who needs a bottom bracket?

Every bike has a bottom bracket, so if your bike is creaking or feels stiff or notchy as you turn the pedals, your bottom bracket might be worn out and need replacing.

What are the choices?

It’s not so much a choice as a matter of compatibility. You need to establish whether your bottom bracket is press-fit or threaded and what size. Then you need to make sure it is compatible with your crankset. If it’s worn out, replacing like for like is often the easiest thing to do.

What should I buy with it?

You need some specialist tools both to fit and remove bottom brackets and to remove the cranks to get at it.

Anything else?

If you’re fitting a bottom bracket into a brand new frame, your frame will need some preparation first. Bottom bracket shell facing tools can be very costly, so you might need to bring it into a bike workshop to get this done.
