I have tested this bike on some great rides. Two local gravel Fondo’s and some. YTD ~1795 miles on the bike. It has been amazing. Once I found the right tire pressures for the terrain every piece in this bike is Solid. Excellent components and room to grow into it. Very adjustable when it comes to tire sizes in the stock wheel set, but also the frame can take skinnier or wider sets. Just a solid amazing product.
I am in love with this bike! This is my first high quality bike, previous multi speed bikes were always bikes from Walmart/Kmart when I was younger or bmx bikes. This is amazing I feel like I can go such a long distance riding this bike and we even completed a 11 mile ride yesterday! Such an awesome bike I am really looking forward to more adventures on it!
For your reference, I am 6'4"/230lb and went with XL. This is my first ever road bike, after reading lots of reviews and articles, decided to go with gravel for its versatility. It has been six weeks and I 've rode 300 miles already. In the beginning, with zero experience I was very skeptical but fell in love with this beauty very quick, Now I go biking 3-4 times/3-5 hours a week. No issues at all, feels very sturdy on the road, very comfortable specially with the saddle for me, better than expected. Shift works very smoothly, brakes the same. overall I am very happy, it has been a great investment for me and my fitness level (lost ~10lb).
Transitioning from a MTN bike to gravel has been great, so far rode this bike at least a dozen times now and its been great! I don't have much experience with different bike brands and bike types, but I spent many weeks doing a lot of research on different gravel bikes. When you look past having a flashy brand name on your bike you finally realize the great bang for you buck you get with the parts on this gravel bike. BUT, bike parts are just bike parts in the end and you can get similar parts on many different bikes. What sold me on this bike is the great service you get at all the REI shops and the 365 day satisfaction guarantee!
Bought this bike as a skeptic. Holy ***t, it's relatively light, and super stiff. Components are top notch. Bike rides like a $6K gravel bike and would stack up against the best. My XL weighs in at 24lbs with pedals which is solid for the price point. Rode Kestrel at 18 RD in Fruita yesterday and the bike was a gas. Only critique is the cables are a bit long and the headset needed some adjustment after thrashing. This bike is probably the best gravel bike for the money out there....and REI will adjust it for a year after purchase. Stoked.
I've been a biker of all sorts for over a decade, and have wanted to get a gravel bike for years. I finally pulled the trigger on this bike, which would be considered 'mid-range' in pricing for a gravel bike. I absolutely love it and have been riding 3-5 times a week. Really have no complaints. I've used on city streets and mountain bike paths. Note, this is not a mountain bike, but it is a very capable road bike. All bikes are designed for a purpose, and while this one is particularly flexible in use, you should consider what you want to do with it when choosing a bike. I ride city streets, bike paths, and gravel trails mostly. One nice thing about riding a gravel bike in the city is I have no fear of bike damage or flat tires due to cracks and potholes, but still go plenty fast.
I'm coming from a much older '80s steel frame bike and was looking for something more modern that can handle roads and light trail riding. I've had my new ADV 2.2 for a few days so here are my initial thoughts: - Weight: Very light and responsive - Build: REI did a good job getting things dialed in before I picked it up. I only made some minor tweaks to the breaks and front derailleur (speaking of those tweaks) - Tuning/Repairability: I know I'm coming from old-school equipment but I can't state enough how happy I am with how easy minor adjustments have been. No more fighting with cables under tension and endless trial and error. - Overall Quality: My only gripe at the moment is the paint. There are one or two spots where it is thick or uneven, and on the Logo there are a few bare spots. I thought it was dirty at first, but when I tried to clean it a little more paint chipped off. It's hardly noticeable, but not something I wanted to see on Day 1 and there aren't any options for touch-up paint through REI. Not something that I'd return over though.
The bike is good for the price. The GRX groupset is as advertised, a great range of gears. I've taken this bike on all kinds of terrain, from deep gravel to basic dirt to road. It performs pretty well on each type of terrain, without being super awesome on any of them either. Basically, a good all-arounder. However, I am still shocked by the condition the bike was in when the local REI released it to me at curbside pickup. The handlebars were angled a full 5 degrees of center. Also, it was clear that absolutely no attempt whatsoever was made to tune the derailleurs. The rear derailleur didn't even reach the two largest rings, and the interval was exactly in the middle of where it should not be. Really basic stuff. Indicative of negligence to the point of utter contempt of the customers. So, while this is a decent bike for the money, I will forever hesitate to buy at REI ever again.
I bought this as my "road" bike for everything that doesn't call for my full-suspension MTB. I've used it for commuting, road rides, light singletrack, long gravel rides etc. I've had a number of MTBs and a single speed commuter, but this is my first bike with drop bars. I've put ~450miles on it so far. It is a size Medium. Gearing - I chose this over the 2.3 because I wanted a 2x10 drivetrain. I like the extra range over a 1x system (I love my 1x12 on my MTB). If I only rode gravel, then a 1x system would be preferred, but the extra gears are great for the mixed duty that I use this for. Brakes - I was a little apprehensive about the mechanical disc brakes, but they've been great. They worked like a champ even when hard braking from speed coming down Mt Evans. I have hydraulic discs on other bikes, but don't see the need to change these. Tires - I'm still working this out. I only rode the stock Nanos for 2 rides before switching to tubeless. They seemed like nice tires, but I am 100% on the tubeless bandwagon. I pulled the 32mm Gravelking SKs (tubeless) off of my single speed temporarily to use for commuting, and they were a pretty good balance of road and dirt performance. I switched out to 42mm WTB Resolutes, which are really nice, but definitely an offroad oriented tire. I rode these on a 70mile gravel trail through Denver that is notorious for goats head thorns. The tires did great, and never flatted, despite many thorns pulled out after the ride (and a number of them making small punctures that the sealant filled in). They feel slow, but my tracking on Strava shows that I only lose maybe 1-2mph over the GravelKings. Now that winter is here and I'll be mainly riding paved bike paths, I put on some WTB Exposure 32s which are fast and comfy on the road so far, but more of a road+ tire than the other tires mentioned. Geometry - I'm not a road cyclist, but the geometry seems a little "sportier" than some other gravel bikes. Pedals - I ride flats on all of my bikes, so I picked up some One Up composite pedals for this bike, that have been working well for me. Misc - I put a rear rack on this (mounting holes are there) for panniers for my commute. The wide handlebars don't take all accessory mounts, so be sure to check the specs on lights/bells/GPS mounts, etc. The paint does seem a little fragile, and I've rubbed off sections where my bike rack touches and where the frame pack that I occasional use touches. I have/love dropper posts on my mountain bikes, but I haven't found a need for one on this bike for the terrain that I ride.
This is my first co-op bike and I have to say I’m impressed. Picked it up during the anniversary sale once stores opened so as not to assemble it myself. Initially had an issue with the front derailleur, but it’s REI. They were great in getting it fixed right away. So far out about 175 miles have been put on it. Climbs hills easily, and rides nice and smooth on both roads and gravel. Has a fairly light frame with solid components that shift smoothly, although I would have preferred hydraulic brakes over mechanical. Overall a very nice bike that performs well and is also pretty to look at.
