What's so special about DID chains that require a DID tool to break and rivet a new link? I have seen prices for the genuine (I think) DID ones between £80 and £180..... ...and then there are those that look exactly the same from between £25 and £45.... I have to do an FJ link for a DID 520 ZVM X ring chain because they don't do a spring clip link for it.......Blast. (although Wemoto infer they do......Anyone know if there is one?) AL.
