Ambrosio seem to have discontinued the Excellight, and stopped doing 28h Excellence too. Also not silver.
The IRD Cadence is a Kinlin XR240 aka Halo Aerorage, and is 24mm deep, and also not available in silver.
Missed the silver request :(
Mentioned the IRD as that seems the easiest to source. If Scorch is in the US then Klinlin should be availible from places like Zencyclery and fairwheelcycles. They do a XR200 which is unsurprisingly 20mm deep, and bloody light. I bet it comes in 28 hole too (weight weenie rims), but I would'nt recommend it for a 100 Kg rider's, fixie skidder ;)
