A 2 wheel drive road so it is do-able on a road bike (my bike had a 28mm on the front and a 26mm on the back). I have ridden the road 3 times on my roadie, twice with no flats and once with 3. Most of the road has a good surface but there are sections of rockier road with large bumpy sections that will give you a pinch flat if you take them too fast. The road is steep at times with 10% sections common. Coming out of Mt Beauty the climb is approx 10km long.
