Pirelli

This tube got me through my hardest century ride yet and is still going strong. I trained with it for three weeks before the ride and used the it for the century. I loved how speedy and smooth it felt. It is a real workhorse too. The training and the ride were over farm roads that were patchy in many places. The Cinturato never failed. It's got the quickness I look for in a TPU but I never had to worry about it going flat. Highly recommended. The only reason I didn't give it five stars is that unlike other Cinturato TPUs, this weight did not have a removable valve core. Probably don't need it though given the reliability.

Have been enjoying these for a few months. Got a flat yesterday from a big cut in the tire (not sure what i ran over). Dissappinted to find both my smartube rs spares had small holes and had to walk home. Either they came with small holes or they didnt survive 3 months in a saddle bag with a multitool, tire lever, and an electric inflator. I recommend checking these when new and keeping them wrapped in something in your saddle bag. Or buy something else!

I had high hopes for this product. Bought a set of these for my TT bike as they tested fastest by BicycleRollingResistence.com. However, upon the very first use, while my bike was sitting in the stand pre-race, the rear tube simply popped! Thankfully I still had time to swap it out and make my start. Because my confidence was now shaken I also swapped out my front wheel for my backup as I didn't trust the tube. It was an extremely warm day, but I even consulted Pirelli about whether I should compensate tire pressure due to the heat. They suggested a couple of psi lower, which I did. Later upon examination, I discovered that the rear tube failed right near the valve at the edge of the reinforced circular section. Don't know if this was a freak one-off or an inherent weakness, but it is hard to recommend the product after this experience. The good news is that BTD gave me an immediate refund after I notified them of the failure. The tube I had in the front I now keep as a spare for now.

These tires are worth every penny. Rode a 500 mile course, some gravel, mostly paved on a titanium bike. Best ride I've ever had. Went through rainy days, gravel roads and really hot days/pavement. They handled well in all circumstances.
