The most critical features of a chain tool are proper plate support, pin positioning, precision threads on the pin driver, and a stiff and comfortable handle. Our Chain Pin Press checks all the boxes, and then some. Designed to work with derailleur and single-speed chains, our chain tool has a 360-degree backside support design and sliding retainer to ensure chains are always pressed efficiently and meticulously. Made from cast and machined CRV tool steel, this chain tool is a one-time purchase, guaranteed.
