Velocity Deep V's: Machined vs. Non-machined

You probably all think this is a stupid question, but what's the difference between machined and non-machined deep V's? (apart from the fact that you can brake with machined rims)
I've heard that machined is stronger than non-machined, but i thought a discussion would solve this.
And please don't just write non-machined is better...

Machined has been milled to afford better purchase for ones brake pads.
Non-machined has not.
That is the only appreciable difference.

is that it? ok cheers

machined rims are designed for a small wheels that connected to a tiny petrol engine to be attach to it, thus you can use your bike as a scooter that go at least 15mph.

a bit like that but for the front wheel;

Has anyone had any experience with fly bikes on ebay?
i'm thinking about getting these:

Has anyone had any experience using the search on the LFGSS?

That is just stupid.
The majority of those fixed wheel riders who use a brake do so on the front so the machined rear rim would be pointless.

thats what i thought, maybe they're confused....

The title is wrong is all...from the pics and this...

The front rim has a braking surface and the rear rim does not. This will allow you to run a front brake only on your bike and still get the no braking surface look on the rear wheel.

Yes. I move too slow.

The 'recieved wisdom' is the other way around, actually. Machining a rim makes it slightly thinner, therefore weaker, than the same rim left unmachined ... goes the theory. 'They' say that the thickness of the wall is more likely to vary as it has been machined flat from a surface that may well not be truly flat to start with (which is because extruding a curve into the strip of metal makes the sidewalls tend to ripple a little).

By the way, its perfectly possible to use brakes on non-machined rims. You might find they're more likely to be squeaky and groany for a while.

@ ma3k's picture: You should try some e45 before bedtime mate.

does anyone know how much import tax would be on them? (the wheels)
