The Hutchinson Sector 28 700x 28c Tubeless Road Bike Tire was first introduced at FrostBike in late February. There was instantly a buzz about the tire as it was a super lightweight 28c road tire designed for tubeless applications. At 285 grams they are already a very light road tire in general. With "gravel grinding" and wider rim/tire set ups becoming more ubiquitous (that's right, I said ubiquitous) this tire was the next logical stop on the "lets get wider with and run lower pressure" express.
We were able to mount these with relative ease onto a set of HED Belgium rims. The profile the wider rim and tire offer is pretty striking compared to what a conventional set up looks like. Much flatter with a larger radius to the curve of tire. So far we've felt the balance between efficiency and comfort lies in the mid 70's psi range. The ride is phenomenal, especially on bad pavement and dirt roads. The higher durometer (see: harder & better wearing) rubber used for the middle strip of the tire helps it roll nicely while the soft textured shoulder sections give great cornering grip even on soft, loose, or varied surfaces. Hopefully this is the first of many new tubeless options suitable for gravel grinding.
