Thanks. I just checked after posting, to see what chain I have now. It turns out I have a KMC DX10sc on there now. Would my Cannondale CAAD10 Rival have come with this chain? I didn't think the chain had been replaced when when I'd had the shop tune the bike before, but maybe so.
So you think this multitool will be inadequate to get the chain off, and remove the excess links from the new chain, or will it just be some extra trouble? I assume with the quick-link I won't need anything to get the new one on.
