Yesterday I received the 700-28 continental ultra 2000 tires I ordered from Nashbar. The reason I chose 28’s was to take the ‘edge’ off the ride on my old Cannondale frame as I was running 23’s. After mounting them they looked a little skinny so I measured them. Lo and behold 23.5 mm.
Is this due to me reusing my old 23/25 tubes or are continental a bunch of liars!?
