Fitting a shock can be complicated. Cane Creek has developed proprietary databases and software to facilitate the process of identifying shock length, spring rate and required mounting hardware. We are in the process of creating web-based applications so that this information is available to consumers and dealers. In the meantime, orders can still be placed online. Simply choose your type of spring and required size and complete your order. A Cane Creek representative will contact you by the end of the next business day to confirm mounting hardware and spring rate. If you are unsure of shock length or are interested in Ti spring options, contact us at 800-234-2725 or sales@canecreek.com.
