Anyone come across these before? The tall aero rim looks like the speedcific rim.

Only came across these as I was searching for someone selling Sun road rims in the UK.

I had a set of their 20" rims on a bmx bike of mine, they were a little on the heavy side, but I they had 0 problems. I've been trying to get the 415gram aero rim for a while with no luck so far. Hopefully it won't take too much longer.
Comparing their spec with that of the Speedcific rim http://oddsandendos.safeshopper.com/9/130.htm?929 they appear identical - same dimensions, same lack of eyelets. Just different weights, which is probably Halo being optimistic.
