I’d own a FS if I lived in a log cabin at the top of the Alpes, but I’ve yet to find a trail in the UK where I wish I still had my FS over my Ti456 (though maybe thats because I need to find some harder trails!).
I think there’s a new generation of bikers with plenty of disposable, who went straight to a full susser and are under the false understanding that if you try and ride the same stuff on a HT, YOU WILL SURELY DIE!!!!
As for LT HT’s you just need to ride a “modern” HT, with short stem, wide bars and 5″ forks versus an old skool butt in the air racer like a Klein (and I’ve owned both!) and you’ll know it makes sense!
