650 x 25 tires

Best to use the tire finder under biketiresdirect. There were others but this one didn't show up under the 650c tires.

Looks like no on Tiresdirect and Rivendell. What is the difference between 650c and 650b?

It'll be tough unless you can find a company providing them to intelligent triathletes.

Here's a good article from the inimitable Sheldon Brown.

28mm could be a great tire for what you do. Don't you ride off pavement a bit with that bike?

I don't go off pavement with the Madone, but I do ride chipseal at times and it is harsh. The 28s are too wide, I have very little clearance.

Not all tires are made the same. I'd ask the folks at Terry to put some calipers on an inflated tire and give you the exact measurement. I'd never make the assumption that all 28s are the same width.

Thanks! Good idea.
