GRAFTON HYPER-C MOUNTAIN CRANK ARMS

There is also a Hyper-C compatible version of the Joystix Mountain cranks. All other aspects of the arms are the same, except the single piece right arm has its swept back spider arms made slightly shorter. The shorter arms bring the outer chainring bolt holes to the 94mm center diameter of the Hyper-C cranks. The inner chainring posts are spaced inward to the 58mm Shimano standard. Nothing much else is different, even the weight is very close. The Hyper-C Joystix crank arms come anodized in Blue, Black, Lavender, Red, or Silver.

They are made in 170mm, 172.5mm, 175mm, 177.5mm, or 180mm lengths. Hyper-C Joystix cranks also come as right arm, with integrated spider, left arm, five steel outer fixing bolts and nuts, and a set of five steel inner fixing bolts. Chainrings, crank arm bolts, and crank arm dust caps will be needed separately. We found Hyper-C Joystix Mountain cranks had a Bike-Pro Q measurement of 155mm. The weight of the 175mm long Joystix Mountain crank arms is 438 grams. The nut and bolts set weighs an added 38.5 grams. Made in USA specify length and color.
