OD 2 > OD and REI = great service
The OD 2 is a nice upgrade over the OD from 2017 and is slightly better than the sport version. Likes: the addition of hydrolyc brakes and only 2 spocets (vs 3) on front. The service at REI was awesome - knowlegable, patient and personal. REI also follows up with a free 200 mile tune up!
It's been a great year with this bike.
So I've had this for a year now; here are some observations. I am 6' and 200 lbs and a large fits fine. I use it on hilly trails and a little on streets - mostly fitness, no racing or wild tricks. If you are getting one bike this handles both well but is not the best at either. The 2x9 drive is awesome ,yes there is some overlap but it gives a wider range for climbing steep hills and rolling at speed down a straight. I upgraded contact points, seat, pedals (oneup) and grips (ergon 3) and the functionality is slightly improved. Also used Suntours discount to upgrade to a Raidon air shock with remote lockout which has been awesome! This bike has held up and held its own with anything I've thrown at it, frame feels sturdy, very few chain drops, brakes great and so on! Great buy!
