Thanks to those who answered my question about covering the back brake. I have another one, and I'm even posting it in the right place this time! I was approaching a fairly tight right bend the other day and I noticed gravel in the middle of my lane and at the kerb side. To avoid the gravel I rode in the 'clean' section between the two areas of gravel. As a result I only just negotiated the bend - and I was only going slow. What is the right course of action in this situation? Should I just stick to my line and trust the tyres? If the bike starts to slip on gravel will it eventually regain grip, or is it the case that once it starts to go - that's it?! Any advice appreciated.
