well , got a set of sprockets and a DID x ring 520chain from Chad at sprocket center (great guy to deal with!) and i have a question. i know i need a rivet tool, but saw on the back of the chain'sboxthat only a DID KM500 was to be used. is this true? i have a rivet tool already so would i need this special one from DID instead? TIA, dan

 

I did an RK chain, but for the most part you need a chain breaker to take off the old chain, and a chain press to put the new one back on.
