(ABC News) Extremely light yet super tough, mountain bikes have undergone a high-tech metamorphosis since the "horrible" days when the likes of Cadel Evans used to hump a heavy aluminium work horse along a dirt track.

Former mountain bike competitor Donna Dall, who now coaches Wright, said new generation mountain bikes were remarkably different from the "awful" beast she had to race 20-odd years ago. Evans, the 2011 Tour de France champion, rode similar sorts of two-wheelers in the 1990s during his early days as a mountain biker. "It was horrible," Dall said of her old bike. "I've got one in the roof and I'll bring it down occasionally and have a ride on it and it just feels awful, and I cannot believe the feats that people like Cadel Evans used to do on those bikes — just amazing." "They were a lot heavier back then, just awkward to ride." Photo: A 2018 edition Specialised mountain bike.

They are made of specially engineered carbon fibre, weigh less than a small child and are designed, optimised and tested using computer programs that fine tune aerodynamics and performance. "They've changed incredibly," Dall said. "Back then they had 26-inch tyres. We're now on 29-inch wheels. "The actual construction of the wheel has changed from aluminium to carbon, which makes the ride a lot smoother, a lot faster — sometimes it feels like it's free speed."
