Minor Threat 2021

$3,950 CAD

We build bikes that we want to ride, the Minor Threat is no exception (we just built this one for our kids!).

When we first decided to make a kids bike, the idea was simple. Why not put everything the grown-ups want, into a pint sized equivalent. Queue: The Minor Threat.

Nothing about this bike is a cheap imitation of your mum or dad's bike, The Minor Threat is the real deal. From the 4-bar suspension layout to the leverage ratio painstakingly tuned for the lighter rider. Or the flip-chip adjustable geometry, low standover, and ample room for a dropper seatpost, nothing about this bike will slow you down (apart from the chomping G2 brakes). The parts spec is equally as impressive. RockShox suspension tuned specifically for this kinematic and rider weight, Maxxis Minion's and not to mention decked out with the finest Chromag kit.  Hell it's even got a 12 speed Eagle drivetrain, this bike might actually be better than your folks' bike.

The Minor Threat comes in two sizes, S1 (24") and S2 (26"), both with adjustable geo to suit your needs. The 140/150mm platform is aimed at a variety of park, trail and jump riding, with progressive geometry that makes the Minor Threat a capable climber and an agile descender.

We know what you’re thinking – “A Chromag bike that isn’t made of Chromoly??” Steel isn’t going anywhere as our flagship material, with titanium appearing on some ultra-premium models. That being said, Aluminum was the best choice for the Minor Threat for a couple of reasons.

Firstly, the use of aluminum allows us to make a bike that’s burly enough to hold up to the bike park without being too heavy for a lighter rider to manage. Aluminum has a lower strength-to-weight ratio than steel, meaning that more volume of aluminum is required to make a frame that holds up to our strength standards. This is why you’ll notice that the tubing used in the construction of the Minor Threat is thicker than that used on most of our steel frames. With this in mind, it might follow that an aluminum bike and a steel bike that have exactly the same mass would have the same strength. This is not quite the case due to some more complicated physical principles involved in the shape and size of the different tubing (like the second moment of area, if you want to really go down the rabbit hole), that mean you can often make an aluminum frame slightly lighter than a steel one without compromising strength.

Another one is that aluminum is pretty low-maintenance. As you probably know all too well if you own one of our other frames, it’s very important with chromoly to grease your seatpost every couple months. If water gets into an ungreased steel seat tube, it will corrode the steel and form a bond with the aluminum of your seatpost, making it nearly impossible to remove. However, this isn’t an issue with an aluminum bike. While unpainted steel is not naturally corrosion-resistant, aluminum is! The secret is aluminum oxide, a chemical compound that forms when aluminum is exposed to air and creates a thin film on unpainted sections of your frame. This film is what keeps aluminum from rusting. So while you should still grease your seatpost (and pretty much every component-to-component interface for that matter) with an aluminum bike, it’s a little more forgiving to being “ridden hard and put away wet”.

Just like the rest of our Taiwanese-made frames like the Rootdown, Stylus, and Monk, the Minor Threat is handmade by a team of highly skilled framebuilders in Taiwan, and is held to the same stringent quality control standard that our frames are known for.

Great bike for short, lightweight adults too

I have been praying for a tiny bike like this all my adult life, and I finally took the plunge and bought one a few months ago. It has been such a joy to finally feel in control of my bike and no longer held back by my equipment. To have the suspension work as intended. To roll up to gnarly PNW features and say hell yes, I'm riding them, because I know the bike is going to do what I tell it to do because ... for once in my life, it fits!! I'm giving it 4 stars only because I didn't love the stock fork (too harsh) and I'd have preferred to get a fancier build off the shelf. I get that for kids there's a price point to hit, but the bike industry should recognize that there are plenty of adults in this size range (mostly women) who are not being well served. (Note the staggering numbers of "what bike to buy the short wife/GF" threads on Pink Bike, etc.) That said, with a fork upgrade this is is a dream bike for anyone <130lbs. in the S2 size range. If you're tiny like me, do yourself a favor and buy it. And yes, the stand over is dreamy. Thanks, Chromag, for making an excellent little bike.

Amazing bike to watch your grom progress

My son has been on his minor threat for 8 months now and watching how it has enabled his progression has been wild. Been doing a combo of North Shore and Whistler Bike park and bike has stood up very well. Build quality it second to none. Climbs pretty well, maybe a bit heavy but again kids are hard on their bikes especially if they are senders so haven’t had to do a thing besides lube the chain. The slack geo and quality suspension has definitely saved his bacon coming up short and riding the steeps. Some people will question spending so much for a kids bike but this bike is so good that you know the resale value will be really strong so in reality it isn’t that crazy when it comes time for the next size. It’s an investment! At least that’s what I told my wife! Lol

Thanks for building it Chromag!

Buy your kid some skill!

I was lucky enough to get one of the first Minor Threat 26" bikes released for my 9 year old boy and it really was a game changer for him this summer. The geometry and suspension on this bike can handle anything the bike park can throw at it and its ability to climb well make it such a great bike for the little chargers. Seriously my son's skills improved instantly with the confidence this bike gave him. HIGHLY recommend. Well done Chromag!

whoop whoop!

Kaeden, our 8 year old son, is loving his new ride! It is still slightly to big for him, but he is having no problems pedaling it. We are a non lift access family (most of the time) and had friends worried about the Minor Threats pedal-ability and weight. Well, a couple weeks ago Kaeden wanted to ride Silver Stars 35km Beowulf loop. He shredded the downs and went up the loooong climb with no problems. He has been hitting bigger roll downs and can't stop popping off of every little lip and drop on all the trails. Fantastic ride Chromag!

Unbelievably stoked!

We just picked up the Minor Threat for our 8 year old son, and he is unbelievably stoked! The geometry, the suspension, the components, it is an incredible build. From climbing, to rock rolls, to the bike park, this bike handles it all with ease. After just a few rides, his comfort and confidence has noticeably risen. Chromag definitely knows how to build a bike! 10/10 would recommend.

Minor Threat Geometry



We decided to make two frame sizes because reach, stack and wheelbase are a much better assessment of bike fit than wheel size alone. These bikes are designed to fit riders who are approximately 7 - 12 years old.
You can run 26" wheels on the S1 (and vice versa), but we don't recommend it as you are merely making the bike taller and raising the center of gravity, rather than increasing the actual bike size.
