I've got a Mavic MA40 rimmed, Shimano 105 hubbed wheel (for screw on freewheel) in 126 OLN, which is true, and was in daily use until a couple of weeks ago that you can have for £10 collected (from Kingston or West End, or possibly anywhere in the middle on my commute in)
The only problem is that it needs a new axle (which you can get for £5 or so).
