• Looks like the FC-M410 is square taper*, so you just have to pick the right BB-UN26 length to suit your BB shell.

    *There are also Alivio chainsets in the M430 series which are Octalink, hence the enquiry. Octalink is the thing which can catch you out, because the early ones with short splines give a completely different chain line compared with the later ones of the same axle length.
