The TL-CN35 Chain Tool from Shimano is their pro-level shop tool, designed for super reliable precision and use all-day long, while having a replaceable drive pin system It was designed for driving pins out chains for sizing reasons, as well as driving a new chain pin in place, with accuracy and ease of use. It is compatible with 9-12 speed Shimano, Wipperman, SRAM, and KMC chains. The application of an oversize ergonomic lever for increased leverage, grip and comfort ensures effective tool control even with greasy hands. Shimano applies nickel plating to the steel body to eliminate corrosion and deliver long-term durability. A textured brass collar system allows you keep the drive pin secure, while still being able to change it out easily when necessary. Conveniently, Shimano supplies you with 2 spare pins in the grip storage compartment. A bent or worn pin should always be replaced to preserve the integrity of the chain plates when driving pins or in out. You don't want to round out or damage the link plates.

Shimano has a few special technologies that make the CN35 a great tool. First, they use a ball bearing between the drive pin and the threaded axle for a smoother rotation and less friction on the drive pin. Second, a molybendum treatment on the drive axle thread further decreases overall system friction for smoother action which turning the drive. The last is the shaping of the driving itself, which has a taper. This taper retains the excess ring that is released from the removed rivet pin when "breaking" the chain, again providing safer, smoother action. This excess ring can easily be pulled off the guide ring after use.
