Let me count the ways...
1. Carbon frame = The speed of "light!" You can focus on your bike handling, really moving the bike around beneath you, and it makes for a nicer uphill pedal, rather than getting tired of heaving around a heavier bike. And I didn't realize how nice the stiffness of the frame was until I hopped on an older bike and thought my wheels were going to fall off in every corner. After a thorough check, it turns out that old frame was just extremely flexible, and after getting used to the carbon frame it was hard to go back.
Great All-Around Geometry = Perfect for the rider that loves the downhill AND appreciates the uphill for the fitness (but really LOVES the descent). I have no qualms with climbing on this bike, it has been great. There might be a "slight" compromise in climbing efficiency over downhill efficiency, but I would much rather have the extra confidence for the downhill and sacrifice (seriously, minimal sacrifice mind you, I probably shouldn't have even mentioned it) a little bit in the climb. I would also argue, that for any woman who feels a bit more intimidated by the descent vs the climb, you should look to this bike. Why not take advantage of a geometry that will help your confidence when you point it back down the mountain? This will infinitely increase the "fun" level of your riding!
Great Components = I have been riding this bike since mid-July, multiple rides per week, and have not experienced any issues. Loving the 1x11 set up, and still riding up the same steep hills I rode on both 3x9 and 2x10 setups.
Tubeless Tires = I am SO happy to be back on a tubeless set up. I have loaned out my mini-pump to many a friend on rides, and have yet to need it myself (knock on wood!)
Fork = I admit, I am not a master suspension guru. I love that they have recommended air pressure printed directly on the fork. I start there and might tweak as needed, it's been working superbly.
This bike would be perfect for most riders! SO FUN!
