Miche chainset/BB chainline weirdness

Thanks for the reply OldSkool. Adjusting the BB 2 mm to the left would be a solution usually, but on my Bob Jackson this brings part of the crank spider too close to the chainstay.

As you say, options are limited. My interim solution was to use a Campag 111 mm anyway, while gathering fundage for a better set-up. Ended up the same as the 107 Miche in my case (i.e. 2 mm out). With an EAI cog on my System EX it was just about bearable.

I am about to fit a Campa Pista crankset (and Phil Wood hub) and I can already see, from a trial fit, that it is going to work out well. Specifically, Campy Pista cranks will allow me to achieve the desired chainline at the front while still clearing the chainstay nicely. That was impossible with the Miche / Miche.

(Obviously if you have chainstays that are indented / shaped then moving a Miche BB 2 mm to the left is no problem).

Sorry i can't offer help with the non-adjustable Miche BB but i've been running the Primato BB and Advanced cranks and found that the 107mm BB does indeed put the cranks too far out, roughly giving prehaps a 44/45mm chainline?

I simply adjust the BB to the non-drive side by about 2mm and hey presto a perfect chainline!

The problem is that Miche cranks use an ISO taper so your only options for BB are;

Campag who do a 111mm version, which is going to be even worse than a 107 Miche in terms of chainline.

Miche adjustable BB 107mm adjusted slightly depending on hub/sproket choice

Phil Wood BB which comes with adjustable cups but is also ££££££££££££!

Doesn't really answer your original question i'm afraid but lays down some options i hope!
