Lust! What rims are they?
They are OEM rims from china. High grade Toray carbon, with kevlar reinforcement, and a polyurethane foam core. They certainly seem strong and light, but the profile doesnt look overly aero TBH. They were'nt the cheapest, but I wanted to have the rear rim drilled without any offset angle. So need to find a flexible supplier. They are drilled for internal rims, which I thought should allow the use of higher spoke tension (smaller hole, with bigger nipple contact area).
For more info. I got pretty much all my info from this thread.
