Chain Size Simulator CSS-1

Made from precision-cut plate steel the CSS-1 always exactly simulates the final size of the chain.

• This tool can be used for keeping the chain in place while pushing rivets in and out and/or to eliminate having to fight the rear derailleur spring while installing master links. 
• One side of the tool has an illustration on where to cut the chain when using a master link and the other side illustrates where to cut when using a rivet.
