Rated 5 out of 5 by from Great hardtail! I don't often write reviews, but this bike this bike! It is by far the best hardtail I have owned. Great mix of components, great geometry, and the 2.8 tires really soak up the extremely rocky trails we have in the Arizona desert. I am very tough on my bikes, and after 2 months of abuse I have not had a single issue. Do the tubeless conversion right away, it only costs a few buck and it takes less than 10 minutes per wheel!

Rated 5 out of 5 by from Modest I purchased the Co-op Cycle 2.1 because it provided me an interesting and potentially very fun bike within my current budget. I am intrigued by the the 27.5+ tire platform as something close to a 29’er, which I love, while giving me a potentially very rideable hard-tail platform incorporating some of the fat bike quality which I also love. The other thing that drew me to this bike was the surprisingly consistent (almost entirely Shimano SLX M7000), high quality, mid-range component spec which I hope will provide some of the highest performance per dollar available today. My personal taste in bikes leans toward understated visuals and highly reliable, quality components in preference to loud colors and/or cutting edge finicky components. The DRT 2.1 appears to meet my taste in both. Before riding the DRT 2.1 for the first time, I removed the reflectors, set up the tires tubeless, and wrapped the right-hand chainstay with some inner tube (over top of the clear plastic protective sticker that came stock). The final total bike weight for my XL is 29.5 lbs. This was pretty much the easiest tubeless install ever. The Novatech Fourtyfive rims have a fantastically tubeless-friendly cross-section (i.e. a narrow drop center and a wide ramp up to the bead seat), and the rims were already taped. I popped one side of the tire off, pulled out the tube, put a Stan’s valve through the rim, put ¾ of the bead back on, poured in about 3 or 4 oz of Stan’s sealant, easily replaced the rest of the bead on the rim, inflated to 35 PSI, listened to a couple of good pops as the bead seated itself, spun the wheel a few times, and voila, tubeless happiness! Then, I deflated the tires to 20 PSI and was ready to ride. The stock, WTB Volt Sport saddle is 135mm wide, narrower that I thought appropriate until I sat on it and found that if fully supported my very average spaced sit-bones. The saddle is quite acceptable. I am riding the stock platform pedals (probably won’t stand it much more than a couple of days). Although, I normally ride clipless, I want to push my mountain bike skills this season, and riding flats should reduce the likelihood of developing or continuing bad habits enabled when riding clipped in. The pedal bearings are pretty rough, and the pins are just part of the pedal casting (cheap platforms). Without pedal washers, the pedals dug into the shoulder of the pedal hole of the crank a bit. Cheap pedals are to be expected on most new bikes, but come on REI, use pedal washers before you tighten cheap pedals onto nice crank arms. I could not make a better tire choice than the Schwalbe Rocket Ron 2.8’s. They of some of the lighter 27.5+ tires available, and their tread is grippy enough while not being too slow. Their size and tread are fantastic middle of the road choices. Sizing: REI claims that an XL fits riders from 6’ to 6’3”. I’m 6’4”. Raising my saddle to my standard crosscountry height places it about ¾” beyond the minimum insertion line on the 400 mm long seatpost. My sense of a familiar reach would put my bars about ½” to ¾” further away. So, for me, REI size recommendations appear to be pretty much spot on. The spec list on REI’s website is lacking some of the specific details. A few more details are as follows: Fork: X-Fusion McQueen RL2 (buttery smooth for a $1600 bike) Crank length: 175 mm Chainring size: 30 T Rims: Novatec Fortyfive, inside width 45 mm, outside width 50 mm, depth: 18 mm Brake Rotors: 160 mm front, 180 mm rear Tires: Schwalbe Rocket Ron SnakeSkin TL Easy 27.5 x 2.8” Handlebar: Width 760 cm, Rise 15 mm, Sweep 15 degrees Stem: Co-op cycles 31.8, 0 degree, length 70 mm Saddle: width: 135 mm REI is great about including useful bits with their bikes. The DRT 2.1 bits include a replacement rear dropout/derailleur hanger along with plugs and ports for the internal cable routing to a front derailleur and/or a dropper seatpost. Tubeless stems were not included. The X-Fusion McQueen RL2 fork is fantastic for a bike in the sub $2000 price range. It looks cool and is wonderfully stout and buttery smooth with good small bump compliance. At the same time, low-speed compression damping seems to be well tuned as I don’t find the fork diving into corners too much or overly squishing out when I apply the front brake. When pulling up the front wheel for manuals or wheelies, there is a bit of a thunk as for fork fully extends. The overall geometry of the bike provides a neutral, stable, but sporty enduro feel, neither too steep, like it’s REI Novara predecessors nor floppy like many older long travel bikes. The chainstays are short enough to provide decent climbing traction and ease of popping up the front wheel, while not being so short as to be problematic holding the front wheel down when climbing steep trail sections. At this point, with one trail ride completed, I’m impressed. Not only did the bike’s component spec and ride quality surpass my performance expectations, the 27.5+ tires, the X-Fusion McQueen RL2 boost fork, and the conservative geometry completely thrilled me.

Rated 5 out of 5 by from All Smiles and Dirt!!! I just received this bike on tuesday, I took it out on wednesday afternoon! First off the entire time i was riding i had a giant smile and even up the uphill sections. This bike is so capable. The boost spacing makes the rear very stiff which helps so much with control and climbing. The front boost helps with those turns and steep downhill section. The fork is butter and super compliant and smooth. It took all the rock gardens and burns like a champ!!! this thing is a super sweet shredder but yet I'm even more pumped to set this thing up for bikepacking! I'm planning one for next month and hopefully be able to write up something somewhere about its ability to bikepacking, and if the the way it rides now is any indicator it's prolly going slay at bikepacking too. The SLX groups is so slick and great at shifting and the ranges on the 11speed make climbing a breeze. Anyways if you dont like having fun on a bike look somewhere else. But if you like ot have fun in whatever type of outnain biking you do this is your bike. you dont need something special or fancy just somethign solid and good just like this DRT 2.1 and if you don't believe me about the smiles I'll include a photo of the smiles!!!!

Rated 5 out of 5 by from New to mountain biking I bought this bike 3 weeks ago with no mountain biking experience. I ride quite a bit, mostly on paved surfaces before now. And I have ridden my whole life but I don't know name brand parts and glaze over when people talk about specific components. What I am saying is I am not an expert. But I can tell you that I absolutely love this bike. I have had nothing but thoroughly enjoyable adventures on this. I am in Flatland( Ohio) so I'm not climbing mountains. But we do have an abundance of rocks and roots with a bunch of creeks thrown in for good measure. I swapped out the petals for clip ins. That was new to me so I fell a bunch. Worth it. All in all I am happy with the purchase and of course the great service and knowledge from the REI staff.

Rated 5 out of 5 by from So good! I got this bike, my first, about 2 weeks ago. What fun! I've been looking for a bike for a while, and I've rented/tested about a half-dozen bikes. In this price range, this bike had one of the best component sets I've seen. I've ridden it about a half-dozen times so far. I live in New England, and the riding around me is mostly rocky/rooty with rolling terrain. The 27+ tires are a nice balance between the maneuverability of 27.5 and a 29er (I had been riding a 29x3). It feels zippy around corners and it's pretty good for rolling over rocks. Converting to tubeless was shockingly easy, as another reviewer mentioned. I pumped up both tires with a floor pump and I didn't even have to try hard or remove valve cores. The 1x11 drivetrain is super nice and leaves the cockpit nice and clear (leaving room for a future dropper post....). The suspension lockout on the handlebars seems unnecessary to me, but it doesn't really bother me either. I'm 5'10" and got a large. It seems to be a great size for me.

Any chance of an XXL? Being 6' 5", this bike is just a little too cramped vs. the competition. Any hope for a slightly larger frame size this or next year?

Asked by: tallguy
As of May 2017, we do not plan to stock XXL. All available sizes are on our website.
