I’ve found that a crankset that comes with rivet-attached sprockets costs the same as cranksets with no sprockets. So we get ripped off either way. The all-in-one piece wastes a crankset everytime the sprocket wears out and probably overspends on sprockets. And the universal crank fleeces you up front by cheating you out of a set of sprockets.

The rivets on my crankset are 72mm apart. Is there any reason I shouldn’t ragefully take an angle grinder to them?

Will I merely have to find sprockets with aligned holes, or could I run into other compatibility issues like mismatched hole sizes or other mating problems?

The bcd cribsheet shows a standard “Shimano 2003 XTR MX960 4-arm middle” has the bolts 72.1mm apart. So it seems I could get lucky though it’s a bit scary that a specific year (2003) is mentioned.
