Tufo C S33 Pro Tubular Clincher

I came across these while looking for a 700x21 clincher for the tight fit on the rear wheel of my TT bike.

Yes they are heavier than a regular clincher but when you factor in the tube and rim tape you don't need they work out lighter.

They mount up a little differently but the instructions are very clear and there are even videos available on-line if you need more help.

I had to bunny hop an under-construction manhole cover on a 47 mph downhill the other day and these tires held up great.

I have been using this brand and model tire for three years. I ride two hundred to three hundred miles a week and have only had four flats during this time. Flats are easy to repair with Tufo's tire sealant. Even though the industry is going to wider tires, The 21 mm tire with 145 PSI performs exceptionally even while descending 28 miles from the top of Mt. Lemmon. Given the price, performance and longevity of this tire, it's an outstanding value.

I was interested in a higher PSI rated tire for recreationaltraining use and so I decided to try the C S33 tubular clincher for a start. The price was comparable to any other tire I would purchase. I weigh 230 lb and rode the tire at 150PSI for approx 300 miles. EXCELLENT ride! I didn't have a pancake of a tire as I normally would in a 120 max PSI tire. Felt fast! And was mildly amused to carry the small sealant bottle for potential flats compared to a spare tube and levers. Here's the problem. I got a small puncture flat with a tiny piece of glass. I used the Tufo tire sealant. It got me home the remaining 25 miles or so. The stuff never dries inside of the tire. I am still getting drips of the solution out of the hole to this day (3 days later) when I try to inflate the tire back to 150 PSI. The tire will not hold the high pressure now. (And I don't want to ride it at a lower PSI... That defeats the whole purpose of buying these tires.) Unless I can repair the hole, this Tufo is trash, and that's the risk you take with this product is higher PSI is your aim. And that is way the overall rating is low. So a great tire for a big guy until you get a flat.

I've been riding on Tufo's for about 5 years. I prefer this model to the others as it's a great value for the price and quite durable.

Thirty years ago I rode on sewups. Anyone who has ridden on sew ups, you know they cant be beat for performance. There fairly easy to replace on the road, but fixing, what a pain! So now Ive gone to Tubular Clincher. I feel the best made are the Tufo brand. Minimizing flats on the road and half way decent road performance (115-175psi). Easy to fix on small punchers on the rode with Tufo tire sealant.

I rode tubulars for almost 30 yrs and enjoyed the upside..fast and smooth, but the downside of hard to mount and fragile. I purchased TUFOs 3yrs ago because the promise of a lighter system of tire ...single tire and tube weighed more than Tufo tire. And the cost was 25% less.

The tires are moderately difficult to put on the and have to be hand stretched over a period of time. It take persistence and a strong set of hands or at least an extra hand. Like a tubular you have to spend sometime making sure the bead is set and tire aligned.

These tires do not come alive till you start running them at 150-175 psi. Below 140 psi they feel like a clincher. Hit 160 psi and oh boy they take off. Silky and corner with security and speed. Old tubular roll off .....never a thought or problem. Punctures...I ride city, urban and country roads and run over glass and road debris all the time...never a problem..I have not used the TUFO sealant but probably should.

Minor issue... the inner stem on the valve stem will come unscrewed if you use a presta valve adapter as I do because I choose the reg stem length and my presta valve pump head tends to blow off at about 150 psi. I use the adapter so I can use the schrader valve head to pump to 170-180 psi. just be gentle when re-tighten the inner valve.

I let my riding partners use my old set of tires to try them out and all it takes is a quick 50 miles to convince them to buy.

If you are considering TUFOs because of weigh, then thats fine, but crank em to 160 psi and have a faster and tighter ride. Just because they are at 160 psi does not mean they are bone jarring. Think supple and smooth.

It's all in the wheels and frame...everything else is just gravy.

I have been riding these tires for close to 5 years now and absolutely love them. I cannot understand why Tufo hasn't established a much larger market. The tubular clincher gives you a similar feel and ride to a glue on tire with-out the gluing hassle.

I have tried switching back to traditional clincher tires and just couldn't do it. The ride on the Tufo's is so much better.

The only issue I have had with Tufo is occasionally I will get a tube of sealant that just doesn't work. I recently switched from the Tufo sealant to Stan's and that seems to have done the trick.

Best tire for the money!
