Now, I’ll take a fair bit of heat for this, including from SuperDave who sells these, but I think the TUFO clincher tubular is the worst of all worlds. I don’t see the benefit.
They are better than clinchers but not as good as tubulars.
The only difference is the extra weight of the strip used to attach to the rim. Also the tubular rim won’t have the extra weight of the lip to hold on the tire.
They are lighter than a clincher tire, tube and rim tape - do the math. But obviously not as light as a tubular.
If you don’t carry a spare tubular, you wouldn’t carry a spare TUFO clincher - it’s the same tire except for the strip.
Have a pre-ridden spare if you’re going to carry one.
They last forever and “never” flat. I use the s-33’s to train on and get thousands of miles, even on the CT. Race on the lites. Haven’t flatted in over 2 years, 2 IM’s and several halfs.
They are cheaper than clinchers after you add up all of the replacement tubes and the fact that they last forever.
