The new Hutchinson Atom Tubeless Road Tires have arrived. They weigh in at a slightly disappointing 283 grams. This is only 13 grams more than the claimed weight, but I was looking forward to these being closer to, or even lower than, the 270 gram target weight. They do look nice in all black, and I hope they perform as well as the Fusion 2 Tubeless we have reviewed and still love to ride.
Update: The Atom tires when mounted on a 19mm wide rim only measure out at 20mm wide - while the Fusion 2 tires measure 22mm wide. This makes them very narrow, but suitable for lighter riders or even as a front tire.
During testing we had one front rim damaged by hitting a pot hole with the pressure at around 80psi. Of course if these wheels had normal tubes it probably would have caused a pinch flat!

NoTubes Alpha 340 Road Rims
NoTubes has an exciting new 700c aluminum clincher road rim that weighs only 340g. The ZTR Alpha 340 700c road rim also uses NoTubes exclusive shorter rim bead. We will build a pair up as soon as we can order some rims - it looks like 28h and 32h are the first options on the way. I hope a 24h is available for lightweight front wheels soon.
Update: Originally rumors on the interweb had these rims as wide as 22-24mm, which is wider than even the HED Ardennes or the Velocity A23 rims. However, according to final specs and report on cyclingnews.com it appears that they are 20mm wide rims, which while closer in width to the Shimano tubeless wheels, they are still slightly narrower. This means they should still be good for a lightweight build.
