[QUOTE Sometimes a crankset will recommend spindle length as "110/113mm." If that's the case, measure the distance between your frame's rear dropouts. If the distance between the rear dropouts is 130mm, use a 110mm spindle length. If the distance between the rear dropouts is 135mm, use a 113mm spindle length.[/QUOTE]

It's some time since this post and I don't know if the author is still in touch with the forum, but here goes!

Why would you use the wider spindle length to suit the wider dropout please, I don't quite see the connection? The reason I ask is that my dropout width is 135mm, but I fitted a 110mm bb, and front and rear deraiilers don't quite mesh together nicely. Should I try the 113mm?
