Highly recommended for bickepacking trips
I have no complaints about this bicycle. I took a trip from Chicago to the Niagara Falls and the bicycle did not disappoint me. It was my first experience making a trip of this magnitude, during the way I took it from paved roads to dirt roads and made changes in my luggage and I had no problem, the bicycle is designed to fit any type of luggage to the best measure. It may not be very light but it compensates with the resistance to large loads on long trips.
Tough Tour Bike
Took this little number on it's first ride down the Central Coast of California. I picked it up a few weeks before riding 300 plus miles and took it on single track, road and various dirt terrain. The way it handles with and without bags is amazing. Even without suspension and flat bars, I was able to rock and roll up and down some nasty gravel and dirt. The 650b set up is super soft and cruises well on all surfaces. I was curious if I would lag behind the pack on a long tour (mostly on pavement) but no complaints. The tires and drop bars make for a great ride with little to no drag. I carried about 45lbs of gear over 5 days on the rear tire and front handlebars. This bike is loaded with bosses to throw bottle cages on anywhere, a hand pump, rear bike rack and panniers. The bar tape that comes stock provides a nice cushion for long and short rides alike. I would highly recommend this bike for anyone looking to ride the distance on any terrain.
Bear bones tough
Been eyeing this bike for over a year-and-a-half . It is beautiful to look at. Finally bought it. This bike is dope . everything i need nothing i don't. Durable and smooth. The ultimate road and off road touring machine. I'd buy this over a surly long haul trucker due to the angled top tube and wide tire clearance. Its like a surly long haul trucker and surly bridge club combined. Wow!! I am runnning 50mm tires with sks fenders and the clearance is perfect. Solid and functional drive train. Amazing dual piston trp brakes. This is a 1 bike qiver. I was unsure of the bar end shifters when I test rode it but after putting a hundred miles on this bike I really appreciate their durability. They feel very strong and indestructible. My only complaint is that the rear axel uses a squewer instead of a through axel. Unfortunately Squewers are still common practice but are also obselete.

Trail Gobbling Machine
Had this bike for a little over a year now and I couldn't be happier. Spent the first year cruising around the DC metro area trail system with the factory bar end shifters that work fantastically off the shelf. Eventually decided to make some upgrades to the drive train and throw a SRAM Rival1 1x11 group set on it and it sets the bike off. I love the steel frame and the big beefy 50mm tires and the 1x drive train turns this already stellar bike into a trail, gravel, road, anything and everything devouring machine. Tons of places to mount racks/cages/bags/whatever you want to make this thing run for you.Well done with this one Co-op Cycles!
Bottom Bracket broke
Bought this bike for a pacific coast bike tour. Shipped to Seattle, seatpost binder bolt snapped at the airport. Jerry rigged a fix to get to a bike shop. Got a replacement bolt, mechanic suspended the bolt wasn’t made from hardened steel. 1200+ miles later in Gorda, Ca I discover the bottom bracket has come loose and I limp along to Cambria to stay the night. Pretty disappointing. I can’t finish my trip to LA. I haven’t ridden this bike more than 2500 total. Difficult to get tires off rim for flat repair. I can’t say this is an REI problem, but more a tubeless rim/tire combo. I tried three types before I could find a combo that worked. I’ve had the bike for less than a year.
One of the best bikes I have ever owned
I have been riding two wheelers for about 63 years. I'm retired now, during my work life I commuted by bicycle for a straight 17 years in a variety of environments as diverse as Pennsylvania, Louisiana, Arizona and California. I purchased a medium ADV 3.1 about two weeks ago and have ridden it every day since on my daily one and two hour morning rides that involve pavement, open desert and hills. It's a winner. The big fat tires are comfortable and roll easy enough, the low low gearing set up is ideal for a guy high high in years. Up till now my favorite bike was a Rivendell Heron followed closely with one of their Rambouiletts. The ADV 3.1 has a similar geometry to the Heron as it's quite nimble handling and allows good power transfer to the rear wheel. Who ever designed and built this inexpensive bike should be applauded. Thank you REI for offering another great product. I'm real particular about bike sizing, I'm 5'6" with a longish torso. The medium is spot on, only thing I changed was the saddle, eveything falls right to hand. If I were to change anything else it would be converting the rear derailluer shifter to friction, but I got to join the 21st century at some point so I am getting accustmed to the index shifter. Great bike!
Built Tough
I ride my Co-op Cyles ADV 3.1 bicycle exclusively on high desert dirt roads. The road surfaces encountered are hardpack, soft, loose sand, animal trails and rough, rocky railroad service roads. After 500 miles, my ADV 3.1 continues to ride as new. My bike weighs 30 lbs. 15 ounces equipped with a rear rack, two water bottle cages, and MKS Allways pedals. Standover on the large frame is 31.75 inches at the midpoint of the top tube. Seat is stock and comfortable. One of my rides starts out with two mile climb over a 4-5 percent grade. The gearing allows for an easy ride over varying road surface. I appreciate the low gears when I work through sandy portions of the ascent. I have not had any problems with the components. The REI bicycle mechanics did a masterful job in assembling my bike. While I have no complaints about the bicycle, I will warn potential buyers that bumping the thumb shifters inadvertently is easy. Bumping the shifters comes into play when storing or loading the bike. When riding, you need a little more shifting skill to work the thumb shifters as opposed to handlebar mounted controls. All it takes is practice and route observation. For the record, I am a mid-60s male who has loved bicycles since I learned to ride on a 20" Rollfast single speed. I love my ADV 3.1--the color, the quality, the steel toughness, the wide tires, and the ride.
Great Bike
After riding custom touring bikes for the last eleven years, my wife and I thought that we would purchase bikes that could be ridden on gravel roads. We were pleasantly surprised with what a great ride we got with the Co-op Adv 3.1. The ride is very comfortable and eases the bumps and cracks of ill maintained country roads as well as gravel roads. This is definitely not a mountain bike, but is able to ride some single track roads. I love the handle bars and bar end levers. The gearing is sufficiently diverse to allow us to ride quickly on flat roads and well as comfortably climbing up 6 percent hills. The disc brakes are very responsive and easily slows of stops the bike on downhills. We have put about about two thousand miles on the bikes since we got them five months ago, and they are our new favorite rides. Thank you REI...you have a winner with this bike.
Lucky to cross paths with this bike
Absolutely loving this bike! Perfect on all surfaces - city streets, bike paths, dirt and gravel roads. Comfortable for long rides. Bar end shifters are easy to use. Looking forward to many adventures together.
