I got my size XL 2021 Expert mid-July here in Norway. Apparently one of the first. Had planned on the comp, but was told it would not be available until November.
I'm really happy I decided to go for the Expert for once. Have previously owned comp carbons (Epic, Camber, Stumpjumper), and this always led to upgrading wheels, mech, brakes and so on, so that the bike would be just as expensive anyway.
Have done about 400k on it thus far, everything from epic gravel climbs, 6-hour mountain adventures, park, enduro trails, tech singletrack, asphalt, wet, mud, dry...both in full lycra or baggies & armor
The bike I've been most happy with over the years was my '16 Camper Comp Carbon, with the usual upgrades. I kept coming back to it, even after the prev gen Epic Evo and Stumpy ST. No more.
This bike ticks all the boxes for me. It's so versatile, it climbs just as well as the prev gen, if not better, it's more comfortable and sure footed, and a lot faster on the downs. Yet it doesn't feel like a big bike. It dances nicely at speed, and is so predictable and easy to pick lines with.
The front is as slack as my enduro bike, and I was surprised to find that this just works everywhere, even on the ups. It feels more balanced than the '19 Stumpy - no need to push the front down for traction. No need to flip the chip for me yet, something I did for everything bar full enduro or park days on the '19 Stumpy.
The new SID fork & shock are IMO a major improvement for RockShox. Plush, yet active in a muted new-car way. Super stiff fork, and they ramp up great. I was surprised how much effort it took to use full travel, yet it wasn't harsh. They also lock out nicely. I did add more rebound damping at the rear than suggested, but that's a personal preference.
The G2 brakes had way too much free movement on the levers IMO, but I cured that by pumping out the pistons using a shim slightly narrower than my rotors. Plenty powerful even with the 180/160 rotors and stock pads.
The Roval wheels seems to be a good evolution - they're stiff, but not so much that they are uncomfortable.
I have (of course) been tooling with the idea of what it would be like to run it with a 130 or even 140 fork, and some tractor tires. I'll try my best to not do that, but it is tempting to try just for kicks. The frame seems solid enough...
I'm about 6.3'', sit at about 81cm, and this bike fits perfectly.
