Quoted message said:The bike's built on a 531c frame and weighs about 9Kg or so, I think.
I'm wondering if something like Cane Creek Volos Track <
http://www.canecreek.com/volos-track-clincher-wheels.html > or maybe
something a little less exotic(!) would "transform the bike" or just
"help a little, maybe". Assuming these would make a difference, is it
necessary to spend this much money to get close, or are we well into
diminishing returns territory?
First off, I'm guessing you've got an elderly frame so check the spacing
on your frame and fork[1][2]. You may want to cold set your frame. A
nice steel frame (as yours is) can be easily cold set to take pretty much
anything, or just have a hub that's one size up forced in.
Modern front hubs will squeeze into 96mm forks but I'm not sure whether
this is wise (I'm running a 96mm hub in 91mm forks on the fixed so it
does work. I'd not be confident that a 100mm hub would fit or would be
safe even if it did).
Front wheel/fork spacings
91 mm Low-end front hubs.
96 mm Older front hubs, especially French.
100 mm Modern front hubs.
Rear wheel/frame spacings
110 mm Rear older track, coaster brake and other single-speed hubs.
114 mm Rear 3-4-speed.
120 mm Rear 5-speed, Ultra 6, newer track hubs.
126 mm Rear 6- and 7-speed (road).
130 mm Rear 7-speed (MTB) and 8- 9- and 10-speed (road).
I suspect that the Velos Track wheels had 120mm spacing and aren't
intended to run normal gears. In practice you may be able to do this,
but it'd probably the warrantly. They're also rather expensive, and I'm
not sure that track hubs would have good enough (any?) sealings to
protect the bearings from the cack on the roads.
In terms of bling, value and weight, Shimano's road wheelsets are amongst
the best. The Mavic Ksyrium range beat them at bling, but maybe lose out
on value. Roval wheels are worth a looksie too.
At the cheaper end, Decathlon have some wheels that are probably 1700 and
something grammes[3] for less than £100 but
If you want something that can be more easily maintained you can't go
wrong with some Open Pro rims, expensive butted spokes and a hub of your
choice.
As to the difference a light wheelset makes, it's something you only
notice when you accelerate hard. Hills are another area where they will
benefit you (by a teeny amount). I'm riding relatively heavy wheels at
the moment and the bike is nowhere near as lively as it would be with
lighter hoops. There's no difference just trundling around, but when the
power goes down I miss that little extra something.

[3] The label said 2700-and something grams, but no wheel is that heavy.
I couldn't find them on their -appalling- website either.
