Rapidé StrongArm HF Crank Arms are made from hollow forged 6061-T6 alloy, making them strong and versatile for use on XCO/XCM/Trail/Enduro bikes. By using hollow forged aluminium crank arms we were able to make the StrongArm HF crankset as stiff as our standard StrongArm crankset but with a lighter weight.
A light hollow core heat treated steel 24mm axle connects the crank arms and is compatible with the most common BB size in use today, BSA 24mm making Rapidé StrongArm cranks compatible with all Shimano® BBs.
Rapidé offers both threaded external cup BBs for 68/73mm bottom brackets plus a Pressfit BB for 86/92mm bottom brackets.
Rapidé BBs are also compatible with Shimano® cranks providing an affordable preformance BB option at a great price for a large range of cranks on the market today.
The left crank arm is attached using a quick and secure twin pinch bolt retention system for easy maintenance and quick configuration changes.
The Rapidé StrongArm crankset is available with a 104bcd spider and chainrings – both round and oval Narrow Wide as well as with Direct Mount chainrings in round and oval with 3mm or 6mm offsets to give you the widest possible selection of chainring choice and the greatest versatility and future proofing.
