Sure, you could find an ultra-light tube and tire, but durability would suffer dramatically, and your costs would go up as you puncture your fragile and expensive tubes.Īs a 180 pound rider on a 15 pound bike, and I generally run 105 psi in the rear and 100 in the front. At 290 grams, it is very competitive from a weight standpoint with a decent tube and tire combination. It is slightly wider than the pure racing Hutchinson Atom Tubeless, and just big enough to inspire the confidence I need on a good, switchback descent. The Hutchinson Fusion 3 Tubeless is about the right size for a 23c clincher. With a tubeless tire, you leave the tire on the rim until it wears out, never having to mount it again, something I have never done with a standard clincher in 25 years of riding. I then deflate the tire, add sealant, and re-inflate. After that, I soap up the bead and let my compressor do the work the first time I inflate it to set the bead. I have gotten to the point where I can hold one part of the rim with my hand and work the last foot of remaining bead with a tire iron inch by inch until the bead snaps into the rim. The key is to have a good set of tire levers and to use a bit of muscle. Mounting a Hutchinson Fusion 3 Tubeless, or any tubeless tire can be a challenge your first time. While the Hutchinson Fusion 2 Tubeless had a different colored center line, to denote a multi-compound tire, the Hutchinson Fusion 3 is all black, despite Hutchinson's designating it as triple compound design. I have been riding my Hutchinson Fusion 3 Tubeless since June of 2010, and it is my preferred tire for the kind of riding I do on my road bike. (If there was ever a Fusion 1 Tubeless, I have never heard of it.) The Fusion line is positioned right in between the narrower Hutchinson Atom Tubeless, and the heavier and more durable Hutchinson Intensive. When I first ran road tubeless, back in early 2007, pretty much the only tire on the market was the Hutchinson Fusion 2 Tubeless.
