Shimano 9 Speed Connecting Chain Pin. Simply discard the original pin when making a repair and replace it with this special replacement pin. The extra-long size includes a narrower starter section for easy entry to the link.
This allows for a much easier reinstall of the pin, no more fidgeting, and cursing at your chain tool. Once the pin is pushed through the link, simply use a pair of pliers to snap off the extra bit at the pre-set perforation.
Original Shimano parts guarantee that all components work perfectly for optimum performance and maximum safety and longevity.
