I might be able to live with a 3mm chain line offset (have to check the
M591 front derailer though) but the other issue is that they supposedly
only fit older Shimano crank sets because of the 9mm splines:

The cranks have to go on super-snug because I am a low cadence masher
and often ride with a substantial load on the bike.

I would be very wary of 3mm. It may work with a dérailleur setup but on
my hub gears it needs to be the right side of 2mm or aggro ensues.


Yes, I'd also prefer an exact match. Those 10-speed deals are really
fickle but the more serious MTBs in 2014 weren't available with the good
old 7-speed anymore.
