610 gram, no good for Vagens
If Vagens needs fast, black rims then carbon is the obvious choice.
If you want black aluminium rims that last, see my link.
You're welcome.
Carbon clinchers are no choice either - this is the ultimate culmination of negative criteria: expensive, heavy as aluminum, bad braking with heat failure issues when using on long steep descends.
