In general they are brilliant! Lock them out at the rear and they ride something like my old old tail with only a slight weight penalty. It’s going downhill that the real big difference shows it’s face. I’m able to pick lines in descents that would have spelt disaster on an hard tail, also the ability to stay sat down and control the bike is amazing.
On long rides, again the rear suspension makes the journey a whole lot more comfortable, taking the buzz out of the trail.
Uphill is still an issue, mainly due to me being unfit!
Basically, I don’t think I’ll be reverting back to a hard tail any time soon. My next upgrade maybe electric.....
