I picked up an older Cannondale Super V-1000 (99 I think) with a dead Cane Creek AD-4 shock. I need to get a replacement. Compressed the shock measures 4 inches from eye to eye and uncompressed (fully extended) it measure 5.5 inches. So should I be looking for 4" eye to eye with a 1.5 inch throw? Thank you in advance for your help.
