WTB Nano Comp 700C x 40 rigid gravel tyre

Fast! The Nano 40c is built for speed, and let´s just politely say it delivers. A 40mm, rounded profile and an elevated centerline provide enough volume for lower tire pressures and a smoother ride while still reducing drag and rolling resistance. This makes for an all out gravel destroyer that can still appease those clamoring for a truly big cyclocross tire. Winner? We think so. So does superhuman, beyond endurance athlete, Jay Petervary.
