@ OP. Come up to the OC area if you want to check out the hot air. You're obsessed with 250 grams on a tour? Give me a break. I can swap between 23 and 32 rubber, and wouldn't even see more than 0.5 mph drop in cruising speed. Dyad doesn't even come close to Deep V. And Chukker is probably a step above Chukker. I would say 97% of those who chime in on wheel-building didn't even have more than a dozen wheels under their belts.
