I feel like I’m starting to hear more and more people doing away with their full suspension and going back to a hardtail, or just giving there Hardtail more time. Not sure if it’s because the modern day “Geo” of these “hard-core hardtails”or “do it all hardtails” whatever you want to call them.
Like I always say, if I lived closer to a bike park like mountain creek I would probably go in Enduro FS Cause it probably just makes more sense but for most of the riding I’m doing and local New Jersey trails I just don’t see the point. These new hardtails Are so compliant steel or aluminum.
FS is just as relevant in a flatter or less rowdy park (just fix a go-pro at your shock and watch how much it's moving), but pedaling an enduro-bro sled anywhere other than 1-2 trails in a park, or at Creek is definitely going to sap energy. Question to ask yourself: is the energy you lose pedaling greater than, or less than, the energy you lose getting beat up by the trail.
I look at it this way: I ride my hardtail (single speed) on most of the same trails I ride my full suspension. My times are generally faster, but that's because I
can't take it easy up hill. Pointed downhill, the lack of rear suspension is obvious when the speeds increase, and I am riding on the edge of control for the bike+tires...but that's part of the enjoyment of that bike. No dropper, no rear suspension, no extra gears.
At the same time, the full suspension allows me to experiment with line choices without the (very real) danger of being bucked/under biked. It has taught me that carrying momentum over something that
looks bad can be faster. My downhill times eventually get faster on the hardtail, but cannot match the FS.
The gnarlier the park, the more likely I'll pick the full suspension to ride, even if I
can ride it on the hardtail. I'll use Sterling, Sourlands, Jungle, etc, as examples. I can ride everything in those parks on a hardtail, but my average speed will drop around 25-30%. Line choices become no fun, at that point; since I don't ride those parks frequently enough to know every inch, a poor line choice could lead to some bad injury.
My actual saddle time for the year is pretty evenly split; I generally don't use the FS in winter, since I don't want to deal with cleaning road salt off of it.
