Sold the old HED 3c tubular. Going to a great home. A trackie!!! Hope it flies for him. Roads just too rough here for using it with a 19mm track tubular.
He got a good deal, and I got money for something I never ever ride.
I'm now on the hunt for a used clincher/tubeless front in the 88mm range among a few of the fastest choices in "modern tire width" options.
I'm perfectly content with the HED 6+ front. I 'can' run it tubeless, and have it taped for it. I hear the 9+ is only super marginally faster at low yaw and only really faster at high yaw. We'll see.
