What about the "Tubular Clinchers" from TUFO? Richard Rose (Toledo, Ohio)

Rolly Polly tires we meassured were closer to 26mm than to 28mm. The Michelin Axial Pro 25mm is only 1mm or so narrower than the Rolly Polly but is a good bit lighter. For most folks, the Michelin seems to give a better overall balance - but the Rolly Polly is still very nice.

Bottom line is that nobody is making a good clincher above 23mm. Veloflex 22's are great (and ride better than many companies badly meassured 28's), the expensive Vittoria open 23's are good - but nobody is making a clincher with a tubular tire type casing in a wider width.

In the old days this was not true - the french makers constructed hand-made tires that had tubular style supple casings but with a bead (the open tubular concept). Giant 650b tires were made like this too - the best of all possible worlds. Performance very much like a tubular, but with clincher convinience.

An amazing clincher in a 24-28mm width would virtually transform many bikes - but nobody has the brains to make it. Veloflex was asked, but they declined - they said they couldn't keep up with demand for their current product.

There is a market nitch out there - Mike Kone in Boulder CO
