A great maximum strength, highly versatile, easy fit upgrade for alloy crank killers
Skip to view product specifications

DMR have been making three-piece BMX style cranks for years, and this new hybrid crank is a belter.


Even once you add chainrings we think they’re definitely worth the money if you’re a regular alloy crank mangler.

The integrated steel axle is welded onto their proven chromoly steel arm on one side and bolted on at the other. This gives convenient fitting and slam-proof steel strength, and they’re not even conspicuously heavy.


It comes with a conventional four-arm spider, but five-arm and direct fit DMR splined chainrings (28, 36 and 38-tooth) are available, making this a versatile set-up. The bottom bracket is holding up OK so far too, although it’s not designed for high mileage.
