I posted my thoughts on my first ride on MTBR, thought I"d repost here:
Picked up the bike on Saturday, weather was stormy so I was forced to wait until Sunday to ride my local trails.
1) I really like the suspension. It works very well. On all surfaces, climbs, and descents, you can really feel that suspension working. Grip is very good with the FS, the rear wheel stays in contact with the ground more so than my previous bikes.
2) Seating position is good, I'm 5'-11" and the bike fits me very well. I feel my CG is nice and low. Like my Trek Stache, the geometry makes me feel like I'm not riding on top of the bike, rather more a part of the bike. I rode 16 miles and fatigue was minimal.
3) Bottom bracket height. This was my biggest concern when reading through this thread on MTBR. On my first ride I had 6 pedal strikes in the first 6 miles. However, the last 10 miles had no pedal strikes. Maybe I cleaned up my riding style and started paying more attention to where the roots and rock are. Compared to my Stache, I'm sure there is at least 1/2" less BB clearance, although I've not measured it yet.
4) Shifting of the GX drivetrain was flawless, I have been running XX1 and GX drivetrains on all my bikes since 1x11 came out. Still a nice system, I have no complaints about shifting. The 28T ring is a bit on the small side but it does help with climbing the steep hills we have here in North GA.
5) The Shimano Deore brakes are good. Not quite XT good but very close. Unlike the SRAM brakes that I quickly swapped out on my Stache, the Shimano brakes on the SJ6F are decent. Good enough for now anyway. Maybe the 203mm diameter front rotor helps make them at least feel strong.
6) Tires/Wheels. I'm sure the stock wheels and tires are on the heavier side. Probably would be my first upgrade would be to throw on a set of Chinese carbon wheels. However, they aren't bad. The tire choices are good, I like the Ground Control on the back, the Purgatory on the front is a pretty aggressive tire though. For my riding, I could do a GC at both ends or possibly switch to a set of Chupacabra's which are so far my favorite plus tire.
7) My only other complaint is the Specialized EMT tool doesn't come with the bike and it's like $45 to purchase it separately. Looks more like a $20 tool to me. Although I really like the idea of being able to tuck the tool up above the shock. I also like the SWAT compartment although I don't have anything in it yet.
I am back to two bikes that I enjoy riding. It's now a difficult choice as to which bike I take to the trail to ride on any given day.
