We noticed a hole in the market for 4B11 cranks. There are many stroker options but none standard size stroke. After teaming up with Callies we exclusively bring you an 86mm standard stroke billet crank. The same strength and reliability you know from other Callies products but without the need for different rod and piston combos.
