This has been the longest time I have been on a carbon HT now, at least by a little bit, and the only time it has been a single speed bike and I am pretty darn impressed. It is quite possibly the highest performing SS overall that I have ridden...light enough, stiff enough, very, very smooth riding, climbs like magic, aggressive handling but not over the top. Great high performance all day bike.
Carbon is such a black box in many ways but if this is a good example of what it can be...and it looks to be exactly that...then we are living in a good time to be a bike rider in search of tall mountains and winding trails.
I still think that when you get right down to it that steel is still the best for value VS. performance in a hardtail bike but this Stumpjumper SS is amazing. In fact, I think I need to go ride it again.
