This is for a tandem conversion. I am looking for 3 pairs of the same crank ideally. Even more ideally 2x170mm 1x175mm. Looking for budget items like strongarms, alivio, etc. but they must have bolted rings.
was thinking once about same set as You, and bought some mt-60 cranks for it
Will check if You want what exactly I'm having, unfortunately cranks have no rings (standard 110/74 fits to them)...
