BB Choice for the right chainline (Miche cranks, IRO Track Hubs, ENO Freewheel)
I am currently building my second singlespeed and this time it costs a lot more money...
I have a question regarding BB choice for the following set up:
120mm IRO High Flange Track Hub
ENO 17t Singlespeed Freewheel
I have checked out Sheldon Brown's article on chainline and he provided some measurements of the common components. According to Brown IRO Hub and ENO Freewheel will yield 36+8.73 = 44.73mm chainline. (Numbers are from his chart: http://www.sheldonbrown.com/chainline.html
Now Miche Primato cranks are meant to be used with a 107mm symmetrical ISO BB to get a 42mm chainline.
If I were to use a 111mm SYMMETRICAL ISO BB instead, I should get extra 2mm on either side.
That *should* give me a 44mm chainline... so just under 1 mm off.
I was wondering if you have any advice on the BB choice for this deal. I am eyeing a Campy Veloce/Centaur, that come available with a symmetrical 111mm spindle. If anyone has had particular success/troubles with using such a combo your input is highly appreciated. I am using an old steel 80s frame if that matters at all. Also, is there a 0.5 mm spacer that I could use on the driveside to get the chainline closer to 44.73?
Any help is greatly appreciated.
