Cheers for advice so far.
I have been on a weekend skills course, learned and loved a lot thanks to ridelines.
I have very good fitness and love climbing the trails. I have and do ride the black at Glentress on the hardtail. Also other trails at Innerleithen. I do take it easy on the way down but mange most of the black at GT. Confidence on rocks and routes needs worked on. Climb to top of mast and back up deliverance are excellent. And I like the trail down to deliverance.
One friend has said to get a dropper seatpost as it would help on downhills as I usually keep it at my climbing height.
I got the HT (titanium) as I race some off road triathlons. I love it, an athem x maybe an option as it could be a fun/race bike too? Or would trance be better as fun bike? Or just keep using HT and buy a few bits?
Road/tri bikes are a lot easier to understand!
