Ok,
I want to put one of these: http://www.sturmey-archer.com/hubs_5spd_XRF5.php on an old bike with 110mm rear spacing (I'll cold set it to 114mm).
• Over Locknut Dimension - 113.7mm
• Chain Line: 3/32” Flat 16T - 43.3 42.7 41.7 41.0
• Chain Line: 3/32” Dished 17T ? 22T - 45.1 43.440.9 39.2
BB shell width is 66mm.
What BB spindle length will I need for correct chainline with a 3/32" chain?
Why are there several figures? Spacers?
What does the "flat" measurement mean?
Thanks![/url]
