    Replace Nexave Chainrings with what?

    Hi

    My bike takes a hammering in the winter because of the snow/ice/grit here in Norway. So I want to swap the all-welded-together Shimano Nexave chainrings for something which will allow me to just replace the middle chainring when it wears out.

    I don't want to change the crank, or crank arms, if possible.

    Can anyone suggest which Shimano chainring set would be compatible to replace the Nexave? The chainrings (picture attached) are 22-32-42. The crank is square tapered (picture attached - note that I screwed the cap bolt back on for safekeeping after removing the crankarm).

    I note that the spider does not have threads on the backside to screw the inner chainring to, which is why the middle chainring is so bulky. I have been unable to find any chainrings which look like my one here...

    It's a Cannondale MTB from 1999.

    Cheers

    Replacement crankset will likely cost little more than new rings, and make this process a whole lot easier.

    Looks like you have one of those cranksets where the granny ring attaches to a "triplizer" middle ring. I've never seen replacement middle rings for this kind of MTB crankset, so you'll probably need new cranks if you want to keep the same gearing.

    With winter grit I'd want steel rings for longevity, which are coincidentally found on cheaper cranksets.

    Thanks for the tips. I'm going to try one of these and see how it goes.
