TRICKLE-DOWN OF technology is a wonderful thing when it means you can now buy a brake 95 per cent as good as the excellent Avid X0 Trail for almost half the price. The only real differences are that the lever is alloy, not carbon, and sits on a bushing rather than a cartridge bearing, so the feel isn’t as luxurious. There’s no bite point adjust and you get a utilitarian grey finish but the brake is only 12g heavier.
