Praxis eCrank HD Alloy Crank Arms - ISIS - No Spider - No Chainring - Black - 165mm PLP|Model Year 17% elastaneThe Alloy HD E crank comes with a new shape for more rigidity and improved compatibility. Compatible with many E Bike motors such as Bosch, Yamaha, Brose, Fazua. HD for Heavy Duty, Praxis knows that some riders ride a little harder than the rest and so created the HD for stronger arms to stand up more than the average crank. There is no chainring mounts on these cranks as they're part of the motors on ISIS ebikes. Who's this item for? Ebike riders,
