Thanks for the post - I think we consistently have had good experiences posted here about ride feel on these tires. At 140lbs, I'd bet you could drop the air down a tad and you'd even feel a smoother ride. I'm 200lbs (only a small, white lie), and I ride the 28's around 90-95lbs

The 28 & 30 tires are a bit large for visual matching to 60s-70s tubulars. The only other clinchers I've ridden that come close to these in visual and comfort are Clement.

It was a nasty track and I didn't see it until I was on it. I haven't experienced what I would consider excessive flats with any of the tires. I've used them on at least six different rims and haven't had any problems

The 700x26 look the best if you are trying to match original look and they are also excellent tires. Last year Mike Kone was selling these tires at Cirque. Jan Heine is coming this year too, so perhaps he will also have some. Good opportunity to take some home with you if you need tires.
