I want an extremely durable tire for use on very rough paved roads. Finding a durable, tubeless tire that is easy to change on the road is difficult. These have worked perfectly. My 28C rear tire lasted 4,000 miles on very rough patched and chip-seal pavement and occasional gravel. The front is still going strong after 7,000 miles and seems it will last at least several thousand more miles. Easy to mount with minor tire-iron use and with a regular floor pump, very durable - one year, two rear tires (I ride 10,000 miles/year) and no flats or even minor slow-leak punctures (using Stans regular sealant). I am using Shimano RS500 (Ultegra) wheels designed for tubeless (no tape needed, no spoke holes in the rim). I am 185lb and ride these on the road at 60lb front and 70lb rear with no problems whatsoever.

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.

I put 800 miles on this tire, mostly on the Tucson Loop. Great tire.

Purchased these to put on C38s wheels. Perfect tire for roads, looking forward to new season in 2024 on these. Will update once I ride more to report how the tubeless setup is working out on these and if the sealant is able to seal punctures.

Purchased for off season base miles and exploring new routes, these roll great and feel burly enough for the occasional gravel sections or rough roads. The Mondo’s have also setup tubeless very easy with a floor pump and have barely lost pressure when I check before each ride. Which most road or gravel tubeless tires I’ve used are flat after a few days of sitting. I’d highly recommend these.

Fast delivery and the products look good. I haven’t used them much yet but they have been very good so far.

Wish these would hold air. I tried every trick in the book to get these to hold air properly; fresh sealant, leave them on their side overnight, etc. No luck. On the road they’re great but having to inflate them EVERY ride is a dealbreaker. Going back to the tried and true Roubaix 2BR’s till this is fixed.

Got these in 35mm as an allroad tire. Smooth and comfy on the road. Reasonable on dirt and mild to moderate gravel, though maybe a bit sketchy in loose stuff. My set has weak sidewalls though. After one ride on gravel, I was having sealant seepage from the sidewalls. On slightly chunkier gravel, I got a through-sidewall puncture that was not sealable. Now I've got one tire with like 200 miles on it and one that needs to be tossed. Not sure I'll be buying a replacement.

I picked up a set for fall/winter riding as my usual weekend route is a puncture nightmare and I wanted something tougher. So far the Mondos have been great! Reasonably quick for an endurance tire, fantastic in the wet, and no punctures! I’ve ridden these in rain and mist a few times now and the grip on wet streets is really impressive. I’m running these on a set of Roval C38s and they were very easy to mount. For real world rising these are an excellent choice and, although the rolling resistance is a bit higher than my usual hoops it’s not bad at all.

Best tires for city route with some gravel imo

I have a set of 32s on a fixed gear used for city riding on beat up streets and recreational long rides. I have well over a thousand miles on these in rain and shine with flawless performance so far. I am running tubes in mine with moderate (about 65 psi) pressure. Highly recommend.

Alright, so here's the deal. I switched to the Specialized S-Works Mondo 2Bliss tires after having a rough time with the Continental 5000's in Dallas. I mean, who likes getting flats all the time, right? Now, onto these Mondo 2Bliss bad boys. Man, Specialized really knocked it out of the park with these. They're not just some fancy tire with a cool name. These things are built to last! Whether I'm just cruising around town or pushing it on the weekends, these tires have my back. And let's talk about that grip - rain or shine, these tires stick to the road like glue. No more slipping and sliding for me. But the real MVP feature? That T2/T5 compound. I've had my fair share of punctures in the past, but these tires are like a fortress against those pesky sharp objects. It's like Specialized knew my struggles with the Continental 5000's and said, "We got you!"

There's no doubt the tyre is smooth and fast rolling but the tubeless performance is poor. I have tried these tyres on two different wheelsets, some Roval C38 and also some DT Swiss HEC 1400s and on both they lose 5psi or so overnight when inflated to 58-60psi. I have tried different valves and also replaced the factory fitted rim tape but the result is the same. I have noticed when washing the bike that tiny soap bubbles form on the sidewalls and air seems to possibly be leaking for there. I have tried 4 tyres and they are all the same. I won't be buying them again once these wear out.

The tires seem quite fast, but the puncture resistance really puts these tires over the top for me. I managed a couple small slices on a recent ride and the casing held despite the depth of the cuts. Not bad for a tire that still performs well.

S-works Mondo 2bliss tires were awesome - easy mounting, no flats or wear issues for about 500 miles, until the sidewall / tread delaminated and I couldn’t repair on the road. Mid ride sealant starting spraying everywhere and tire would not hold air. Glad the issue didn’t cause a catastrophic failure at speed. Maybe a defect, but for the price, should there really be quality issue like that. Super frustrating.

These are a perfect training tire! They are light and relatively thick as opposed to my race tires. I do not feel like I will get a flat if I go on a bit of gravel. They are smooth on the roads and I feel like I am soaring through my rides.

I have the 35mm on my Crux, set up tubeless and use it on road and light gravel. Grippy on corners, fast on the road and 100% confident on the fast descent vs my old 23mm on the road bike. Light dry dusty gravel, road, bumpy roads no problem.

Just put these on and took them on one 50 mile ride, so haven't really put them through their paces. I replaced a set of Roubaix Pro 30/32 size with these in 32mm. However these tires are noticeably narrower compared to the Roubaix. Ride quality was great and rolling resistance felt minimal, as advertised.

Was waiting for these to come out as I wanted to try 32s on my Aethos and these tires hyperbole description piked my interest. Boy, did they deliver! So far I've ridden about 800km with them and they are a dream, rolling amazingly well in the less than perfect Toronto streets while eating potholes like a champ! I couldn't pass on the new discount and just bought a backup pair. Which, to be honest, with how well these are built, might just sit in a closet for a couple years.
