Alright, I've now put in 100 miles and 10,000 vert ft. This bike is great. It's super quick and I'm very happy with how comfortable it is on ~30 mile rides. My Sid 120mm fork still needs a bit of tuning. It's fine for most uses, but it feels pretty harsh on fast + bumpy descents. Today I added two volume spacers and gave it a quick spin. Feels better. Still gonna need to play with the psi and rebound a bit. The Specialized Ground Control (Grid) tires have impressed me. Time will tell how durable they are, but they have plenty of grip in the loose stuff.
I've been working my way through the local trails to find how this bike compares to my gravel bike and full suspension bike. On the flat-ish XC trails I've found that my Chisel is as comfortable as my full suspension bike, and more fun to ride thanks to the lighter weight. In the steep and chunky stuff I'm still riding a bit tentatively. I need to get the tire psi dialed in a bit better so that I can soften the feeling of being pinged between rocks. This is more of a hardtail issue than a Chisel issue, but I do need to learn which bike to grab for a given ride.
I finally weighed my bike for the first time - 25.75lbs. In my head I was hoping to keep the weight under 24lbs, but the spec list was more important to me than the weight. Still, even 6 hours into a ride I have no issues getting this bike up to speed.
I'm a little surprised that Specialized doesn't have some higher spec models in the Chisel line. I'd guess that parts availability has something to do with this. I wonder if they're saving the higher end components for the Epics/Stumpjumpers/etc. With a little bit of marketing I think this bike could sell extremely well.
