Shop-grade tools differ from home mechanic versions in two ways: they survive all-day use without wearing out, and their wear items can be replaced rather than requiring a whole new tool. The Shimano TL-CN35 Professional Chain Tool addresses both requirements with a nickel-plated steel body that resists corrosion and a replaceable driving pin system that keeps the tool in service for years. Shimano includes two spare pins stored in a compartment inside the handle grip, so you can swap a bent or worn pin without hunting for parts.

The TL-CN35 handles 9 through 12-speed chains from Shimano, SRAM, KMC, and Wippermann. Like the home mechanic TL-CN29, it uses a ball bearing between the driving pin and the threaded axle to reduce rotation effort, plus molybdenum treatment on the axle threads for smooth operation over thousands of uses. The tapered driving pin retains the excess ring released from the rivet when breaking a chain, preventing that small piece from dropping into the works or onto the shop floor.

Where the TL-CN35 separates itself is in the oversize ergonomic lever. The longer handle provides more leverage with less grip force, which matters when you are sizing chains all day rather than once every few months. The textured brass collar system that holds the driving pin allows quick replacement without special tools. When a pin eventually wears or bends from repeated use, you unscrew the collar, drop in a fresh pin, and get back to work.... Read More
