Although the label on Bontrager's XR2 Team Issue says 2.1in, the tall, round carcass swells up more like most brands’ 2.25s. This means decent rollover smoothness and rock-shrugging security despite an impressively low weight.
Bontrager were among the pioneers of tubeless-ready tyres so it's no surprise it’s sealant ready and low-pressure compliant. It accelerates quickly, the staggered centre tread with softer siped flank treads turns in smooth and rolls pretty well too. It's reasonably priced, but a sod to fight onto rims, so be prepared to be patient with fitting.
