I had these tires installed in February and have had both fail already. I had tubeless tires on my prior bike last for years and now I am down two tires in three months. I will be changing to a different manufacturer for my new tires, very disappointing!

35 mm is a pretty good fat slick tire. Light, supple, and puncture resistant. I ride these on a crux and they maintain the bike’s handling better than a smaller tire would. Unfortunately one of my tires doesn’t hold air for more than a few hours. Not the fastest rolling but it is cruises along well for a big tire.

I've had the 32C Mondo on my new 2024 S-Works Roubaix SL8 custom build on Zipp 303 Firecrest wheels (25mm internal width) since it was built at the beginning of this year (2024). So far, they've been great on these tubeless, hookless wheels. I have several hundred miles on them riding on paves roads, paved trails (sometimes in rough shape), and some unexpected coarse gravel. No problems, no punctures, and they feel great with only about 60psi of pressure in them (I'm 6'3" and about 99kg). The wheels and tires also hold pressure very well. So far I've been using Stan's Race Sealant, but that will likely change once I have to put new tires on. Unless I have problems with them this summer, these will likely become my standard tire for this bike.

I rode this tire around Taiwan and didn’t flat a single time. These are really fast and really durable- an impressive combination. When will we see tan walls?

The tubeless performance is horrible. I've tried: fresh tape, different brands of tape, fresh sealant, different brands of sealant, new valves and have used them on 2 different sets of tubeless rims but no matter what they leak a significant amount of air. They lose roughly 20 psi a day and are virtually flat after 3 days. I honestly really wanted to love this tire. They are great on the road and gravel, no punctures and they're wearing well after 1000km but they will not hold air. I've been running tubeless for 4 years using tires from Continental, Vittoria and Giant and I've never had an issue with tires losing so much air daily.

Equipped a second wheel set with these 35mm Mondo's for my Diverge Comp Carbon to deal with cobbled roads - great choice!

Bought these because good punctures score to rolling resistance on Bicycle Rolling Resistance. Set up was pretty easy, needed one lever but that gave me some confidence. Pumped up with a hand up and held air perfectly through the first ride. Can’t wait to be on these for long rides all summer.

Great product, great price. Confident riding tire, performs flawlessly!

At the 800 miles mark, these are losing air like crazy through the porous sidewalls, even with lots of fresh sealant. Never experienced this with Conti 5000 or Schwalbe Pro One. It's horrendous, as I need to reinflate tires every ride... after four days they are at 18 psi from 70psi. Totally hate them as a result, and since thread has plenty of life I feel badly throwing them away. Avoid. Pros: long wear, no flats, good grip on dry and wet, good dampening. Cons: loses 20psi a day, not the fastest or lightest.

I have put 1,000 miles on these and the wear indicators look like brand new tires. They send me twisting through descending switchbacks like I’m on rails.
