Stinger Flamme Rouge is the top-end, tubular tyre disc from aero gurus HED, with a smooth, responsive, full-feature performance to match, at a surprisingly affordable price. It’s a metal spoked wheel underneath, but the super-broad 28mm outer rim is carbon, and the Flamme Rouge also gets flexible high modulus carbon-fibre skins to form the toroidal shape, although they’re still flexible covers rather than structural.
Ceramic bearings and titanium skewer drop weight further. You can get some brake rub, and they’re soft if you really crank the pedals hard, but the ride is outstandingly smooth for a disc. Low weight spins up to speed and climbs quickly too, and in performance terms, it’s a real bargain.
