The small RCP chain tool is not only an indespensable helper both at home and in the workshop, but also can be a valuable asset when on a tour. If the chain is damaged or needs to be changed due to wear, the RCP Chain tool is perfect piece of equipment to have to hand for your 6-10 speed. No additional tools are required to push out the rivet pin, dismantle the chain or shorten as required.
Warning: When fitting a new chain, or resealing a shortened one, use a replacement pin or a chain lock. To not do so can be dangerous.
