Affordable but tough cotterless cranks from Indy unicycles. These are great for swapping used cranks out on any of the Indy Trainer unicycles or if you want to add a different feel to your unicycle. Generally speaking, The smaller the ratio of crank length to wheel size the quicker the unicycle. Equally, the larger crank the more control the a rider will have. Size is measured from the middle of the axle hole to the middle of the pedal hole. Sold as a pair.
12" and 16" unicycles can only be fitted with 102mm cranks otherwise the cranks touch the ground when pedaling.
20" unicycles: 114 cranks give a smooth fast ride but make idling harder, 127 cranks give more torque and are good for learners and tricks, 152 are too long.
24" unicycles: 102 cranks are very smooth and should only be considered if you are a speed fiend, 127 cranks are smooth and still quite fast, still OK for idling, 152 cranks are great for learners.
