I can only comment on the winium tub rim - nice wheels but zero braking in the wet on the shiny rim surface.
Ironically I wouldn't recommend using Corima's own cork pads on their rims. They brake fine with pads from Campa for instance and Swisstop Yellow King (which I found way too grabby).
Corima has changed its distribution policy again so prices on the rims and wheels may vary from one country to the next.
Still the rims are absolutely top quality but I wouldn't go for any of the earlier clincher rims as these were not meant for tyre pressures higher than 8 (?) bar. This may seem high enough but I seen them crack open more than one.
I must admit that I don't see much point in running carbon clincher anyhow as there are more cons than pros over their tubular version IMHO.
Nevertheless if the TS wants as set of older Corima clinchers I know of a shop that sells them really cheap. So PM me if anyone 's interested in those.
