Three-piece steel crank with external bottom bracket

BikeRadar score4/5

Welded steel three-piece BMX cranks are uber-strong but tougher to fit than external bottom bracket (BB) types. This cunning hybrid combines the best of both worlds.

The tubular 4130 chromoly arms are crashproof, and a lockring-secured alloy spider lets you run four-bolt, five-bolt or BMX-style single chainrings. 

The driveside crank is fixed directly onto the thickwall axle, with an extra deep socket connection onto the splined offside crank. A long steel bolt drives deep into the axle for total lockdown. 

The payoff is weight – and you’ll need to add £30 worth of chainring – but they’re super stiff, well priced and come with a decent FSA BB.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
