I've been around and around on this one. Where to go with the old XTR952 crankset and M950 BB.

Love the 185gram BB with adjustable cups that you can grease and keep running. Hate the rings that you can't replace without getting a home equity loan.

Options?

1) new spider. hard to get in the US. And then what if my old BB finally craps out...hard to find a replacement for that.

2) New crankset....but they are all so expensive. New XT? $270? That's what I paid for my XTR 5 years ago. Any options. I'm scared of ISIS, should I be?

Looking for creative solution for a lightweight crankset that doesn't cost an arm and a leg.

thanks.
