What Arm Length do I need?
To an extent, it’s personal preference. Traditionally, BMX cranks have been 175mm, but this evolved from BMX racing. Since the advent of park and for street riding, especially for riders running pegs, shorter arm lengths like 160 and 165mm have become popular.

What Bottom Bracket do I need?
Cranks nowadays usuually don’t come with bottom bracket bearings – this is so you can select the BB you need for your frame. You need two pieces of information when ordering a BB – the crank’s spindle size – in this case 19mm and the BB size of your frame – see image below showing the types. Choose your BB here.

Fitting
Don’t forget to use grease in your bearings and your pedal threads when installing cranks. See our note about pedal fitment here.
