Until recently, I have only ever used my mountain bike for recreational rides on dirt roads, 4WD tracks etc, not much on narrow, twisty tracks impoosible for a vehicle. Now, I am getting interested in more tricky terrain - but still not anything like racing, jumping off drops, riding up flights of steps etc.
What is the best way to deal with tracks eroded into a narrow slot just a bit wider than the tyre? There are lost of places here where the track is only half a metre wide, worn down into a V with a trench in the bottom. Once in, there is no way out until the other end. How to maintain control when there is almost no room to turn the front wheel?
