(Mods, let me know if this is Spam...)

All -

I've got a set of M960's in 180mm that I love, but my knees have been letting me know it's time to quit the long-crank experiment. Does anybody have a set of 175mm cranks of similar value they want to trade? I'd prefer to stick to 960's (and just trade arms only), but would also be up for a full swap, rings and BB included.
