130 wheel works fine in steel bike. The chainline will be slightly off - but if you are using older 8 or 9 speed there is no issue. If you plan use the 10 speed spaced freehub, then I suggest getting the frame properly 'cold set' as you need to not just space the drops apart, but actually shift the whole triangle to set the chainline correctly. And after that - drops need to be adjusted perfectly parallel otherwise when you clamp in the QR you will cause rear hub shaft to bend slightly resulting in rapid bearing wear and increased static loading.
Alot happens back there, from an engineering dynamics POV, the more accurate you make the system , the better it will roll and last longer.
Does that mean that I am doing (serious?) damage to my frame and wheels? Or, that I might be faster if I had the frame coldset?
I don't understand why the chain line should be slightly off: is this because in flexing the rear dropouts it is unlikely that both sides will flex the same amount?
