Will these cranks work
In my search for shorter cranks, (bad knee) I ran across these "BMX" cranks.

Is there any reason they wouldn't work on my 110/74 triple on my 86 RockHopper? Both are SQ. taper.
Any caveats?

I don't think those cranks have the mounting holes for a 74mm granny ring, and you might need a different length spindle. Otherwise they should work fine.

I don't use the granny (flat land riding), but I prefer to keep it just in case.
I kind of "half expect" that I might need a different spindle length.
Are BMX spindle lengths much different than MB spindles? I'm currently using a 122? MM cartridge.
I realize that different cranks can vary from manf. to manf. to some degree. I'm just wondering if I should expect to need some non standard (or expensive) length, or if finding the right size shouldn't be a problem.
I can "fudge" the chain line a bit toward the 2 larger rings.
Thanks for the replies!
