Hutchinson Fusion 2 Tubeless Road Tire

I'm totally sold on the concept of tubeless tires. I put a bit of Stan's sealant in mine and haven't had a flat in several thousand miles. They also hold pressure much better than any tubed tire I've ever had.

I love running at about 90 psi in the early season to cushion my back side and when the road is really bad. Even at that pressure I don't feel like I'm adding appreciable rolling resistance.

An interesting feature of these is that I can hear them echoing as I roll down the road. Sort of like a radial tire on a car.

My only complaint is that the tread is not perfectly straight on my front. And I suppose I'd like to see a lighter version.

Been running tubeless on my mountain bike for three years. This Spring I converted my twelve year old Bruce Gordon touring bike with its Mavic "Module 3 SPB" wheels. First I calling Stan to make sure that these wheels could be converted, then bought his tape and valves, and carefully watched his online video about how to convert road wheels. Paying attention to detail makes the difference. If you're not the type of person who pays attention to detail, my advice is to stick with tubes. If you do like to work with you bike and spend the time to follow instructions according to the directions, you owe it to yourself to try tubeless at some time in your life. My guess is you won't go back either.

I know I won't go back to tubed tires, for two reasons. First, for the same inflation pressure, these Fusion 2 tubeless tires ride like butter compared to other high quality, high thread count road tires. The Fusion 2s stick like glue and feel extremely stable in turns, also.

My road setup would not have held air without Stans, but even if it did like it does on my mountain bike, I would still add Stans. Why? Because this way I don't get flats if I pick up a thorn and small sliver of glass. And, in fact, even though my mountain bike setup holds air tubeless without Stans, I still put a couple of ounces to each wheel for the same reason.

A point of information, one needs to add Stans about every ten to twelve months depending on how much you ride, the temperature and humidity of the area, because it very slowly dries out. I found this out the hard way when I picked up a thorn on a mountain bike ride and lost air. Normally it would seal in just a couple of seconds with Stans, but in this case it didn't. When I got home and investigated, I found that after a year, the Stans had dried up and the air was leaking audibly and palpably from the thorn hole. I removed the valve stem, put in another 2 ounces of Stans, pumped up the tire, and the Stans leaked out for 2-3 seconds and sealed up... like it always does.

I am in my sixties, weigh 148 pounds, and I am not a racer by any means. So I can't speak to the suitability of these tires for racing or for heavier riders, but for comfort, cornering, and the reassurance of knowing that flats are virtually a thing of the past except for a side wall tear if one hits an object that causes this kind of damage, I am sold on these Fusion 2 Tubeless tires.

Riding on tubeless tires is half way between a hard-tail and a full suspension bike. They mounted easily on my mavic ksyrium elite wheels. They are bombproof. They aren't the lightest tires available, but my times have actually increased since I've been riding on them. I don't know if it's because I'm riding faster since it's later in the season or lower rolling resistance. I do know that my times didn't go backwards.

My front tire needed Stan's sealant to hold pressure up. My rear tire has no Stan's and needs three pumps from my floor pump between rides. My front tire needs the same number of pumps now that it has Stan's. I'm going to put some Stan's in the rear tire anyway - I just wanted to see if it was really necessary.

These tires mount up and inflate infinitely easier than tubeless mountain bike tires I'm running Dave's Speed Dream Wheels on my mtn bike. The Hutchinson's inflate without soaping the wheels using a floor pump. This is inconceivable in my experience on tubeless mountain bike tires.

Bought a set of Fulcrum Racing Zero 2-Way Fit wheels and Fusion 2's. Very difficult to mount. Once inflated they didn't hold riding pressure for more than four hours. I re-inflated them and put them in a bucket and found a seven inch line at the interface of the wheel and tire that was very slowly losing air. Six hours later it was flat. Hutchinson doesn't respond to inquiries apparently feedback isn't of interest to them so I have no idea what the issue might be. I don't see why I should glop up my wheels with sealant to make an already heavy set up even heavier just so the tire will do what it's supposed to do without the sealant- hold air.
