I've just started riding MTB (been a roadie for a while) and started tackling some of the trails on Table Mountain. The tyres on the second hand bike need to be replaced and I'd like something with good grip. I've been struggling on the slippery steep gravel sections (up and down) and need some advice on something I can feel confident on. I'm not interested too much in speed right now, just want to get comfortable before pushing the limit. What's a good combo for our mountain? I weigh under 65kg and riding 29'er non-boost dual sus. Appreciate some advice..
