Hi, I'm new to the forum and new to mtb racing. I did my first xc yesterday in Fort William, Scotland and survived (just!). I was fine with the climbs, but the decents were fast and technichal over varied terrain, with some pretty heavy mud in places. I did the race on Specialized Fast Trak Pro tyres. I think I would benfit from a tyre with greater grip, as I am not a confident descender. I'd happily sacrifice some weight for a bit more grip and confidence on the downhills. Also, what tyre pressure would you recommend for racing a technical/wet course?
