I have an older Miche Primato Advanced ISO crankset that came with an FBM sword frameset I bought. The crank is fine but the bottom bracket is on it's last legs. Looking to replace it but want to avoid the original Miche 107mm ISO adjustable bottom bracket.

Was thinking of using this instead: https://www.retro-gression.com/colle...bottom-bracket or this https://www.retro-gression.com/colle...bottom-bracket

Reason being is I don't want to mess with the adjustable cups anymore. Also, the crank barely clears the chainstay (Backs of the spider have been filed down some already) so I figure the 109mm spindle length can't hurt. I don't really care if it gives me a 43mm chainline.

Is there any reason not to give this a go? Hopefully Scrod can chime in since I'm sure he has lot of experience with this . Figure if it doesn't work out I can always purchase Sugino 75 arms but those aren't cheap and it's my around town bike so less bling the better.
