FAQ

No. These cranks are designed to not use pedal washers. Installing pedal washers can damage the crank as the pedal will not be threaded in sufficiently.

Yes, but you will need a BB86 conversion bottom bracket available from Praxis Cycle Works.

The cranks are designed to specifically for 68mm wide BMX bottom bracket shells and require no spacers. Spacers may be required if your frame has a bottom bracket shell that is less than 68mm wide.

No. A chainring can only be installed on the inside of the spider.

No. A loose pedal will damage the crank and can cause injury. Always ensure that your pedals are tightened correctly.

Notes:

BB86 frames require Praxis™ part 86-4001B.

BB30/PF30 frames require Praxis™ part 68-4001R or 68-5401R.

T47 frames require Praxis™ part 47-0000.

Do not use pedal washers when installing pedals onto these cranks. M30-M cranks were designed to be used without pedal washers.
