Great Ride Great Bike, Poor Assembly
I understand the new Co-op line represents REI's attempt to become a 'serious' bike shop/vendor. This bike is a great entrée, but the shop at my local store still lags behind. THE SHOP EXPERIENCE: First, I never got the call saying my bike was ready and wasn't notified until I called to check on it. I was surprised that they wheeled it out, rang me up and said 'enjoy'. No review of the bike, no sizing, no test ride. No other bike shop would allow you to buy a new bike and walk out the door with it as if you had purchased a shirt. (3rd bike I have purchased from this REI store, and far away the poorest assembly and store experience). First Ride - Front thru axle came loose, appears it was never checked and was 'finger tight' not to 10nm as clearly printed on the end of the axle. Seatpost was greased, a common practice that is questionable with a suspension seatpost and QR seatpost collar. I had to remove, clean with solvent, tighten collar to keep seat from sliding down the seatpost. Second Ride - Bikepacking tour Adirondacks, the rear rack failed when 2 fixing points loosened (see photo). Front rack fixing bolt also came loose and was lost. There is no excuse for the thru axle failure. The racks could be expected to loosen with intense use and require tightening and loc-tite. THE BIKE: It rides great! Tires performed well off road at 18-20lbs pressure and onroad performance improved at 30lbs. Best Features, Jones Bars!!!!! I can't say enough about how this has changed my touring world. Handling is improved, hand positions and sheer comfort. The brakes are smooth and confident, I was pleased. The shifters on this bike are a gem. They are solid, secure and give that no-questions-asked performance. They feel old school reliable. The geometry of this bike is perfect for it's intended use. The saddle sucks! I've toured extensively and never had issues with my bottom until using this saddle for a week. I'll be removing it this week and replacing with my Brooks B-17 . The gearing on this bike is for extreme terrain and I appreciated that. On the road, I frequently spun out in highest gear (36x11) and have to become accustomed to coasting, but I consider this the lesser of evils and appreciate having the low end. On the low end, I could not imagine ever needing a 24x46 tooth gear producing just 14 inches of travel per pedal revolution. I thought I'd fall off the bike. Off road, fully loaded, in extreme terrain, this granny gear saved the day again and again. I found that even though very slow, riding in that granny gear was far more efficient and energy saving than walking/pushing the bike and I ended up using it far more than ever expected. This gear probably has no use if the bike is not loaded up with gear. Suspension Seatpost - USE THE PROPER SUSPENSION plug. The bike comes with 3 and you must insert the one appropriate to your weight. THE SHOP DID NOT DO THIS and it requires some dissassembly of the mechanism. The suspenstion seatpost does help, but does not replace front shocks. This also affects ability to use a large seatbag as is common in offroad bikepacking today. Thusly we are forced to use a rear rack which has drawbacks when offroad. My final conculusion is that this is my dream touring bike. I'd be comfortable on this bike(with a new saddle) touring around the world in all kinds of road conditions. It is NOT a true bikepacking bike (such as the Trek 1120 instead I'd compare this to a Trek 920). But would suffice if trail is not too extreme (Try removing front rack and using a roll instead, and minimize weight on rear rack). The front rack is far more solid and reliable than is the rear one though. It handles well, but got wobbly with weight high on the front rack. I didn't use front panniers (I normally do on road tours). It is a SLOW bike, but it is comfortable, rugged and feels stable and solid under me. I'd give it 5 stars if the shop had done a better job of assembly, review and double checking those high stress areas like rack bolts.
So far so good!!!
I bought my bike in excitement and couldn’t wait for it to come in. I finally got the email to come pick it up that in was in the store. First impressions... Was perfect till I rode it after getting home. Bar wasn’t centered and in the right position. The front mount was/is bent. Everything else I adjusted to my liking. Great bike over all! I did half-ish (58miles) of a 108 mile bike ride from Tok Alaska to Delta Junction. Gonna go in to my local REI to see what they can do! If you plan on doing a lot of pavement riding.... just plan on beefing the tires with 30-35 psi to make it rideable lol.
The FJ Cruiser/Jeep Wrangler/Ford Bronco of bikes!
I love the ADV 4.2- very smooth gear shift- comfortable to ride anywhere, anytime of year, loaded with gear. Can anyone recommend a kick stand for this bike?
Great bike! Will turn heads
I rode this across the country and it was a dream. I could ride where those skinny tire road bikes could not and the burly frame coupled with front and rear racks meant I could carry WAY more than I truly needed. I had a bit of trouble with the rear axle alignment (not sure if this is peculiar to through axle bikes) but got it fixed halfway through. Get some armor for the tires... they look tougher than they will perform against normal road debris (glass and nails are trouble no matter what).
Lots of Great Features
Overall, I give this bike 4.5 stars, but since I can't designate a half-star, I had to round up to 5. There are many great features about this bike and only a few drawbacks that probably come down to personal preference. The following list isn't complete, just some observations I've developed so far... PROS: >> The low gear is astonishingly low (a little over 15 gear-inches), and this is a very good thing for touring steep backcountry dirt roads, old mining roads, and fire roads. Such a low, low gear is possibly this bikes best feature. >> Torque specs are listed all over this thing. As a former helicopter mechanic, I LOVE that detail. (Granted, this mainly applies to performing maintenance at home because nobody brings a torque wrench on tour. Even so, these guides do give an idea for how firmly to tighten the critical fittings in the field, torque wrench or not.) >> The rims have eyelets in the spoke holes for added strength and durability. This is always a plus for a touring bike. >> The Thudbuster Seatpost is a joy to sit on! This is an absolutely amazing device. I've got about 600 miles on mine, and I simply LOVE it. I suffered a serious lower back injury in the 90's, and had surgery in 2004, but this thing keeps me riding. >> A flat handlebar is a huge plus, but there's one catch about the Jones Bar. (See my list of CONS below...) HIT OR MISS (depending on personal preferences): >> There are good and bad things about the aluminum frame. I like that it doesn't rust, and I trust in its strength. Afterall, fighter jets used to be made of aluminum. Nonetheless, I'd worry about it if I were riding this bike across Mongolia or, say, through India because if it cracks or breaks, nobody can fix it. >> Thru axles are in the same pinch as the aluminum frame. I like them and they're great until you need a replacement, then you may not be able to find one in certain parts of the world. >> High gear might be a little short of the mark at only 90 gear-inches. Usually 100 is a good top-end for a loaded touring bike, but touring (and this bike) aren't meant to be fast. CONS: >> The Jones Bar steers like a backwards boat tiller, not a handlebar of any kind (sorry, Jeff). I truly think the Jones Bar is overhyped and I'd be far happier if this bike came with a traditional mtn bike flat bar or better yet, a different "alt bar." That little change would serve this bike very well. >> Only 32 spokes per wheel? That makes me cringe a bit, especially when I think about all the long-distance off-road touring cyclists who swear by 36 or even 48 spokes (at least on the rear wheel). >> Hydraulic brakes... great for a day ride, but BAD for long distance touring. This bike should be fitted with mechanical disc brakes. With these hydraulics, you can look forward to messy oil that's heavy to carry. Further, a hydraulic system will require bleeding sooner or later, and you'll know because the brakes will feel like old sponges. To accomplish this task in the field far from civilization means you also have to carry special tools. Good luck keeping your fluid out of the rain and/or dust on a stormy/windy day. Hydraulic brakes may be this bike's worst feature. >> the Steering Tube comes pre-cut from the factory which means the handlebars have to be *relatively* low. Such a configuration is a holdover from bicycle racing, but this isn't a bike to be raced. This is a bike for touring, and touring is best when it's slow. Thus, wind resistance doesn't matter. An upright seating position as high as the customer wants should be made available. So, there you have a few of my thoughts on this bike. Overall, it's an excellent bike that has the potential to give many miles and years of reliable performance.
Go Anywhere Bike
Great all around bike for use on urban streets, bike paths, fire roads, and moderate mountain trails. Been riding this bike a few days a week for about 8 months and thoroughly enjoyed the ruggedness, comfort and stability of the bike. I also own a nice road bike, but prefer to ride the ADV 4.2 - for me, it’s just more comfortable and fun. PROS >> Quality components all around. The shifting is precise and the gear range allows the bike to tackle steep hills comfortably and also cruise at reasonable speeds on level ground. The Jones Bar is wider than most handlebars, but it’s comfortable and allows for different hold positions. The front and rear racks provide versatility and either one can be removed to reduce overall weight. >> There’s a feeling of safety and stability on the ADV 4.2 due to the durability and ruggedness of the frame, large wheel set, and more upright riding position. Brakes are solid and very reliable. >> Versatility. Because it’s a go anywhere bike, I don’t worry about road conditions or type of riding. I can easily mix into my route different surfaces and conditions, beginning on street surfaces, switching to a hilly fire road, veering off to a mountain bike trail, then returning home through urban roads. >> Very reasonable price point for the level of components, equipment and accessories offered on the ADV 4.2 CONS >> The bike is on the heavy side. The compromise to durability and ruggedness is the use of heavier, more rugged components (esp. frame and wheel set) which can add weight to the bike. However, because the bike is so well geared, weight has not been an issue in terms of climbing. This is definitely not the fastest accelerating bike from a stop, but it’s smooth and will get you steadily up a hill. >> Versatility means it’s not going to be the best bike in any one category. This bike can be used on roads, but it’s not lighter or faster than a traditional road bike. The bike can also be used on fire roads and mountain trails, but it won’t be as smooth as a mountain bike with full suspension components. >> The WTB tires are supple but not highly resistant to goat thorns which are abundant in my area. I changed out to thicker, more durable Maxxis tires. The ride is a bit stiffer and the wheel set is now heavier, but I avoid having to stop and patch leaks. You’re not going to win road races, cyclocross events, or scream down single track routes with jumps at high speed with the ADV 4.2. But it you want a highly versatile, rugged, safe and comfortable all around bike you can use for commuting, bike-packing, or general recreation, the ADV 4.2 is an excellent choice.
