2009 Interbike: The Reynolds system features a two-depth inner. The clincher sits in the deeper valley when mounted.
Dubbed a “Bead Seat Clincher,” the Reynolds system features a two-depth inner. The clincher sits in the deeper valley when mounted. When the tube is inflated, the clincher’s bead is pushed out into the top valley. Since the tire’s bead circumference is substantially smaller than the rim’s outer, the tire sits snugly.
