2021 Hardtail Mountain Bike Top Picks

2021 Trek Roscoe 7 Mountain Bike Hardtail

The best hardtail mountain bikes can smash almost as hard as a full-suspension bike and force you to learn to be a better rider. They’re more affordable, easier to maintain, and come with a certain pride that you just can’t replicate on a full-sus bike.

A good hardtail mountain bike is underappreciated. Modern geometry has brought them back into the spotlight a bit, but most riders just don’t understand how great they are.

Best Hardtail Mountain Bikes

2021 Trek Roscoe 7 Mountain Bike Hardtail

Trek Roscoe 7 Hardtail Bike

Trek Roscoe 7 2021 Bike is built as a great bike for beginner and more advanced riders alike, and they have a great point. The plus tires are confidence-inspiring for those new to mountain biking, and can be pushed hard by experienced shredders.

The build kit and price, however, may be a bit more beginner-friendly. The 120mm (100mm on size XC) RockShox Judy is a solid introductory fork that may be a bit overwhelmed by more aggressive riders. The SX Eagle 12-speed drivetrain is a good budget choice, but the Shimano non-series brakes probably won’t be enough for more experienced riders.

There’s no doubt that the Roscoe 7 is going to be a blast to ride. Plus-size hardtails are an underappreciated group of bikes. And it’s hard to beat that price for the quality of this bike. Just worth noting that intermediate and advanced riders might want to step up to a build with a more capable fork and brakes. One of the best hardtail mountain bikes under $1,500

Price: $1,349.99

2021 Santa Cruz Chameleon A R Complete Mountain Bike 2021

Santa Cruz Chameleon Hardtail Bike

The Santa Cruz Chameleon is one of the original hardcore hardtails. And it has aged very well. Santa Cruz has kept the geometry modern and continued to update the build kit to ensure that modern riders get what they need.

This Santa Cruz Hard Tail Mountain Bike’s particular build comes with a Fox 34 Rhythm 120mm fork, a high-value NX Eagle drivetrain, and SRAM’s Guide T brakes. Those Guide Ts are a great addition to a bike in this price range, as they give you the four-piston power you’ll need when you’re riding a bike this rowdy.

While stock tire choices are often driven by availability, Santa Cruz made an interesting choice here that gives you some insight into the character of the bike: a Minion up front and an Ardent Race in the rear. This hardtail bike is meant to be efficient and fast, but also hold on when the going gets really rough (and still super fast). One of the best hardtail bikes we tested for 2021, a staff favorite.

Price: $2,399

2021 NINER AIR 9 RDO 3-STAR BIKE 2021 Hardtail Mountain Bike

Niner Air 9 RDO 3-Star Hardtail Bike

The steep head tube, low bars, and 100mm fork tell you what this bike is for: racing cross-country. This is one of the few carbon bikes on our list this year, and you’ll notice right away when you lift this thing off the ground. It’s feather-light.

The 3-Star build kit is great for budding and experienced racers. The Fox 32 Step-Cast Float Factory fork is a huge highlight. Step-Cast forks are extra light, and the Kashima coating just screams speed.

The GX Eagle drivetrain is a step up from many of the other bikes on this list, and will provide great performance while cutting weight. The only thing that seems like an oversight on this bike is the lack of a dropper post. But many cross-country racers prefer a standard post to save weight, so it could be forgiven this time.

Price: $3,800

2021 YETI ARC CARBON C2 BIKE 2021 Hardtail MTB

Yeti ARC Carbon C2 GX Hardtail Bike

Believe it or not, the C2 is Yeti’s budget hardtail (there is a C1 that’s slightly cheaper, but it’s harder to find). The main reason is Yeti’s phenomenal carbon frames. Yetis are very light compared to similar bikes, and the ARC is no exception.

Of course, you get a fantastic Yeti build kit — this company never skimps on components. The Yeti ARC Carbon C2 inclusion of a Fox Performance 34 130mm is a nice touch, as it gives the bike slightly more capability on rough trails. The SRAM Level TL brakes might not pack enough power to stay in control on very steep trails, but they match up nicely with the almost-XC vibe of this bike.

Beyond that, what do you need to know? It’s a Yeti. It’s crazy light, has great construction, and comes with a certain reputation.

Price: $3,900

2021 Diamondback Sync'R 29 Carbon Mountain Bike

Diamondback Sync’R 29 Carbon Hardtail Bike

Diamondback has been trying hard to reclaim its name over the past few years, and bikes like the Sync’R 29 Hard Tail Mountain Bike Carbon are helping it do that. Take a look at the specs of the Diamondback Sync’R Carbon you might be pleasantly surprised by the value that Diamondback can offer.

Start with the carbon frame. Then check out the Fox 34 Performance fork with 140mm of travel (a great alternative to all the 120mm forks on this list). Don’t miss the GX Eagle drivetrain, a step above the much more common SX Eagle. Don’t forget the four-piston brakes. Or the threaded bottom bracket. The modern 35mm handlebar. The dropper. The trail-ready tires.

Diamondback has clearly consulted real riders in creating their new bikes. The 66º head angle and 74º seat tube angle are modern enough (though maybe a touch slack on the seat tube). You’ll be hard-pressed to find another bike this well kitted out, easily the best hardtail mountain bike under $4,000.

Price: $3,650

2021 Canondale SE Trail Bike

Cannondale Trail SE 3 Hardtail Bike

With updated geometry for 2021, the Cannondale Trail SE 3 is put more in line with modern trail-focused hardtails. But a few details show that its true purpose is more in line with an all-around bike that combines riding to school with occasional trail trips. The integrated kickstand mount tells you all you need to know.

That being said, a 120mm fork and a 66.5º head tube angle will definitely help you on descents. An included dropper post gets the saddle out of the way for shredding. Shimano’s Deore groupset has gotten a ton of accolades as a fantastic value. And the 1×11 drivetrain is what you’ll find on many higher-end bikes.

Who is the Trail SE 3 really for? It seems to be for people who want an around-town bike combined with a trail bike. It’s an interesting niche. But Cannondale has done a great job of nailing it, one of the best hardtail mountain bikes for sale under $2,000.

Price: $1,300

2021 Ibis DV9 Mountain Bike Hardtail Carbon

Ibis DV9 Deore Factory

Ibis has been making waves with its AF line lately, but don’t forget the DV9. This is still built of Ibis’s vaunted carbon, keeping weight down and helping quiet trail chatter on rougher rides. That carbon also makes it race-worthy at a much more reasonable price point than some of the racing whips out there.

With “progressive XC” geometry, you’ll get a bit slacker head tube and a slightly steeper seat tube than previous generations of cross-country bikes, which is great in the Ibis DV9 Deore Factory. Geometry has come a long way. But this bike sticks to its roots by focusing on XC.

As for components, Ibis hit the sweet spot to stay under $3,000. A 100mm Fox 32 Step-Cast fork is a great choice here for saving weight (and that Kashima bling). Deore components are developing a great reputation for value. And the dropper gives you more room to move when you’re not on the racecourse.

Price: $2,775



2021 Marin San Quentin 1 Complete Mountain Bike 2021

Marin San Quentin 1

If the Marin San Quentin 1 looks a little like a dirt jump bike, that’s because it’s supposed to. Marin combined elements from their dirt jump frame with modern trail geometry to create a very capable hardcore 27.5 hardtail mountain bike. This bike is meant to get rowdy.

This is the budget build, it’s not one of those most expensive bikes however you get a lot of value. It’s one of the best mountain bikes for under $1,000 without rear suspension. One of the highlights is the 1×9 MicroShift drivetrain. You don’t see this on many stock bikes, but it’s a great way to save some cash without giving up much gear range. It’s awesome to see Marin supporting this smaller drivetrain competitor.

Beyond that, you get what you might expect at this pricepoint — 120mm Suntour fork, Tektro hydraulic disc brakes, 27.5″ x 2.6″ tires, and several Marin components. The biggest thing lacking here is a dropper post. It seems like a big drawback for how aggressive this bike is meant to be ridden, but that’s how you keep it this cheap. You can always add one later!

Price: $899


Surly Krampus Hardtail Bike

As one of the first brands to embrace plus and fat tires, Surly knows what they’re doing when it comes to big bikes. And the Surly Krampus is definitely a big bike. You can rock tires up to 29″ x 3.0″ on this bad boy.

Why would you want to do that, you ask? There are two ways to answer that. First, because it’s different and cool and very Surly. Second, because bigger tires are a hell of a lot of fun. They’re super grippy, take a lot of chatter out of the trail, and are surprisingly great on the climbs. Of course, they’re also quite a bit heavier.

The Krampus comes with a solid build kit made up of Shimano, KMC, RockShox, SunRace, and other reputable brands. But you don’t buy this bike because of the build kit. You buy it because it’s a ridiculously fun bike that you can ride on absolutely any terrain. (And because one of the available color options is “Demonic Sparkle Party.”)

Price: $2,299

2021 Bombtrack Beyond Hard Tail

Bombtrack Beyond+ 27.5″

Bombtrack is a small German bike brand that’s slowly becoming more available in the US. It’s a great brand dedicated to adventure on two wheels. They originally focused on gravel and adventure bikes, but they’ve added a few mountain bikes to their lineup, as well.

The Beyond+ is a great bikepacking or all-around rig. 27.5″ x 2.8″ tires give you versatility over the widest range of terrain possible. Lots of bosses let you mount racks, fenders, bottle cages, and whatever else you need to put in long miles on your mountain bike.

A SRAM SX Eagle drivetrain is a great choice for a bike just under $2,000, though you do sacrifice a dropper post (Bombtrack sees this bike as more of an adventure bike than a singletrack shredder, which also explains the rigid fork). One of the best hardtail mountain bikes under $2,000

Price: $1,999,99
