The Chamois Hagar GRX Gravel Bike

Evil Bikes could be considered the hard-partying younger sibling of the bike world, with their cheeky paint color names and rowdy geometry. The Chamois Hagar is precisely what we should have expected when Evil designed a drop-bar bike: genre-defying and stoke-providing. The Hagar may not be called purely a gravel bike, for it is much more nimble to ride, but nor is it simply a drop-bar mountain bike, for it is much more efficient on smooth surfaces. The Chamois Hagar leaves it to you to define where and how you want to ride and will happily come along for the journey, be it gravel or dirt, singletrack or fire road, adventure commute or bikepacking trip.

Where most companies start from a road bike to get to a gravel steed, Evil started from the opposite end of the spectrum with their mountain bikes like the Following to create a stable and fast gravel machine. The Hagar’s geometry might make the pure gravel racers balk: a 66.67° headtube angle, long top tube, 80mm bottom bracket drop and designed around a 50mm stem. These mountain-inspired features all contribute to superior off-road handling. The slack headtube and 57mm fork offset give the front wheel greater contact with the ground for smoother handling especially at speed while descending on rough terrain or singletrack. Riding a rigid bike off-road can feel choppy already, so the 80mm bottom bracket drop helps keep the wheels planted both as we pedal through washboard and rocks as well as through corners. With the headtube angle and fork offset placing the wheel further out front than on a typical gravel bike, Evil eliminates the chance for side-swiping our toes with the wheel on those tight turns.

A frame that’s ready for anything needs a groupset that can keep up, and Shimano’s GRX group is the natural complement with its gravel-centered design. Wide-range gearing makes climbing up to that next pass feel less daunting, and the powerful flat-mount brakes keep our speed in check on the way back down the trail. The GRX rear derailleur’s clutch mechanism and construction better handle the small, frequent bumps of gravel riding, to avoid accidental shifts and chain slap. Evil spec’d the Chamois Hangar with a suite of gravel-ready components to ensure we can keep rolling on varied terrain with optimal handling and efficiency. The WTB Proterra wheels and Venture tires help resist puncture and grip through corners, while the Easton AX-series handlebar’s slight flare gives us a stable position for launching the attack to the snack stop.

I Wanted to Hate It

I've used it several times
6` 1"

It’s different and that’s scary, right? The Chamois Hagar is not your typical bike. It’s proof that numbers on paper don’t always translate to the riding experience. I mean, a 66.67-degree head tube angle on a gravel bike? You might be saying, “What was Evil thinking?” I know I was, but once you ride it your opinions quickly change. The Chamois Hagar is basically a dropbar rigid mountain bike whereas most gravel bikes are road bikes with room for fat tires. That’s what makes this “gravel” bike stand out from the bunch. If you could only have one bike to do absolutely everything, this is that bike. And if you have a stable full of bikes for every type of riding then you still need this one. It has its quirks but I think the grins overshadow them. Seriously, this bike is silly fun. So, what are its quirks? Well, the slack headtube and long wheelbase mean you need to work it around tight switchbacks more. Another one is when you stand and pedal the bike doesn’t sway and counterbalance beneath you like other bikes. It wants to stay upright. A little strange but it’s something you get used to. And then finally it’s stiff. Thankfully, it comes with carbon bars and wide tires that help absorb the chatter. It’s a compromise for a frame that can take more abuse than your typical gravel bike. The bike can handle going downhill faster than you will probably want to go. If you care more about the adventure of riding a bike than setting PR’s, the Chamois Hagar is for you. There are faster gravel bikes and there are more capable hardtails, the Chamois Hagar sits right in the middle. Let’s just call it what it is, an enduro gravel bike. I am 6’1” and the Large felt great.

I've used it several times

I took this bike out on a gravel adventure around the north side of the Salt Lake in Utah with a buddy.... and I had a blast! The Chamois Hagar is dialed in on the gravel roads! The geometry is great for those long descents on sweeping gravel grades as well as those inclines that slowly rise up to the next pass. The long wheelbase, as well as the added dropper post, give you a lot of confidence on the descents even on the roughest of roads. And you don't feel too slacked-out for long arduous climbs. It felt a little "mountain bike-y" when you needed it, and a little "road" when you needed it as well. The GRX drivetrain is really nice and the 1x system really makes it. The less moving parts, the better! Also, the dropper is key. Some of the more technical and steeper descents are made a whole hell of a lot easier when you can drop your butt down. Really like the Easton EA70 AX for the handlebar. The extra degree of flare really makes for a lot of different positions to swap between on those long days in the saddle. I'm pretty much 6 feet tall. I was on a medium with the seat post up pretty high. I would definitely go with large. I just felt a little cramped on the medium and made it work for the day, but large is the choice for me. Have fun on the gravel!

Best Name Ever

I've used it once or twice and have initial impressions

First of all, 5 stars to Evil for the clever pun in name. That's how to start off on the right foot. "It's ugly" is the first comment I've been hearing on this bike and honestly, it's a little weird but it'll grow on you. I'm sure '90s riders would think current mtbs are ugly too. "Who needs that slack a gravel bike?" Is always the next question. Definitely not everyone. If you're racing Dirty Kanza, look elsewhere (not to say this bike couldn't do it, but there are better suited bikes). But if you want to ride 75 miles of mixed fast rolling gravel, some singletrack, sketchy atv trails, and steep forest roads, this is the bike for you. "Does it handle weird?" No, it handles better than you expect. I don't think this is the last gravel bike you'll see with these angles. When you hop on in a parking lot you'll notice the front wheel flop over but as soon as you get riding all you'll feel is a very stable bike. The wheelbase is long so it's not going to be ideal for tight woodsy trails or u-turns when you drop a bottle, but when you hit steep rough stuff you want this confidence. Uncooperative weather only let me ride this bike on mostly pavement for a few days so this is without a doubt a first look review, but based on the brief experience I would buy one. Fit was absolutely perfect on a size large with a 50mm stem and 42mm bars (I'm 6'1" with a long inseam and am usually between L and XL), and I could just tell that this bike will handle the rough terrain I love. Parts spec on this build is impeccable. I'd expect to upgrade the wheels but the current WTBs are just fine to start and the rest of the parts are what I would choose on a build. Some may complain about limited tire clearance for this style bike, but 50mm is almost 2" - that's plenty! I will demo again just to make sure it climbs ok (will steering wander on loose steeps?) and handles a bikepacking load (it's got the braze-ons for everything). Even on pavement with 50mm WTB Venture tires it cruised along just fine.


Update after putting a few hundred miles on the bike: the Hagar my new favorite gravel bike. It's very comfortable putting in 50+ miles of flat and fast rolling gravel (I'd go with something lighter and snappier if that was all I was doing), it climbs very well, and once again it gives so much confidence on descents. Going back to my regular gravel bike which I used to feel confident on, the downhills felt nervous. If you're riding in jeeps trails or forest roads in the mountains or on loose or rocky terrain, this bike is for you.

Not As It Seems

I've used it several times

A quick review of the geometry and visual inspection of this bike would understandably lead one to assume it just won't work. I admit feeling highly skeptical when I saw the first press releases concerning Evil's foray into the drop-bar world, but thankfully I was quite wrong. Every concern I had about the Chamois Hagar was assuaged the moment the rubber met the dirt. The bike pedaled efficiently, didn't flop around on steep climbs and absolutely charged downhill. If you have felt that most modern gravel bikes still borrow too much from road bikes, then this is for you! Wide bars, upright body positioning, and a long wheelbase all combine to make for the most stable ride I've had without suspension. The long tubing and raked out fork certainly take time to visually adjust to, but I believe Evil is on the cutting edge of what the "allroad" genre is all about. As is the case with most ideas that push us forward, you can't knock it till you try it. At 6'00" I comfortably rode the MD with a 50mm stem.
