The Joseph Kuosac or JK road bike cranks are a great crankset for the tall rider, with lots of possible configurations. We are stocking 190mm, 200mm, and 210mm. These cranks are forged aluminum and hold up very well. They come with an ISIS bottom bracket and chainrings. These cranks use an interchangeable spider for ultimate versatility. You can choose between 110bcd, 130bcd, and 130/74 bcd. Chainring options include 34/50, 39/52, and 30/39/52. Special orders can be made, and will be added to our stock orders. That means there may be a wait time for a size we don't carry. These cranks come from Taiwan, so we cannot order single cranksets for special orders. Jk Road crank spiders are compatible with most chainrings that use the appropriate BCD. 9, 10, or 11 speed chainrings are compatible.
