This is a 50mm carbon wheel. They roll really really nice - and are really stiff. I have probably 10-15 rides on them. The tires - 34 Challenge Griffos have been ridden the same. Both are in basically new condition.
The tire sidewalls were sealed with Aquaseal and the tire was mounted using Belgian tape - I have never rolled a tire.
Price - $500
I will ship them for $25
