Chromag Lauched the New Minor Threat

Chromag Lauched the New Minor Threat

Chromag Bikes (Canada) - Press Release: The Minor Threat.

We design stuff that we want to use. That's how every Chromag product has come into existence, and as some of us are parents, the Minor Threat is no exception.

The keener eyes amongst you might have noticed this bike is a full suspension, also fondly referred to as a twin squisher or double boing-boing. You might also be surprised that our first foray into this domain was with a kids bike.

The truth is, even though this is a kids bike, it's a rather technical engineering exercise. Nonetheless, we have a whole host of talented people here at Chromag that were eager to push their skills into the full suspension dimension.

We were also just really excited to design a (frankly) f**kin' awesome kids bike, especially as almost all of us grew up riding klunkers that were nowhere near as good. I think my first "mountain" bike was a Raleigh Nexos, and even your most underbiked gravel rider would pass that up in this day and age. That didn't stop me shralping that thing through the local woods though, and chasing that feeling of freedom is what the Minor Threat is all about.

Kids are growing up with 12 speed clutch drive-trains and will never know the pain of running an over-engineered chain guide that is as good at keeping your chain off, as it is on. Don't get me wrong, this isn't a bad thing, think of what these kids will be capable of in 10 years time. Hell, look at what they're capable of now. I'm not too proud to say these groms might actually require better gear than we had back in the day. With that in mind, we set about designing it for them.

The Minor Threat has a 4-bar linkage driving 140mm of rear wheel travel tuned for the lighter rider. The S1 size sports 24" wheels and a 140mm Revelation up front. The S2 has 26" wheels and a 150mm Pike.

The progression of the Minor Threat is 18%, which is relatively low when compared to an adults bike. It was designed like this to ensure the entire range of travel can be utilised by a lighter rider. However the average leverage ratio is higher than that of an adults bike to help with suspension setup at low air pressures. The rear axle path is typical of that of a 4 bar linkage. It moves rearward in the first 50mm of travel and returns gradually up to its 140mm limit.

It has a 64° head tube angle and a 76° seat tube angle, which can be steepened by 1° with the installed flip chip, depending on what floats your boat. The S1 has a reach of 360mm and the S2 has 400mm, both of which can be increased by 10mm in the steep position. They both have ample room to install a dropper post, and come with QR seat clamps.

We're also rather proud of the build kit as it's no different to what you'd find on most of our own bikes. SRAM Eagle drivetrains, G2 brakes, Rockshox suspension and Maxxis Minion tyres are a few highlights, not to mention we've obviously decked it out in Chromag parts including the all new, kids specific Vanguard 720mm bar. The purple anodised hubs on the Black Candy option are another highlight, not even the adults can get hold of these.

The frame is made from double butted 6066 aluminum tubing, with billet machined aluminum linkage plates and junctions.

Hang on, aluminum?? We know, steel forever right. Well... not quite. Material selection is a huge part of the design process. We make bikes from titanium, pedals from plastic and bars from 7000 series aluminum (We did actually play around with a steel bar/stem combo at one point). For this bike, aluminum made the most sense for a number of reasons, which we'll go into below this lovely photo of a CNC spindle covered in milk.

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 our steel frames.

A big one, especially for a kids bike, is that aluminum is pretty low-maintenance. As you probably know all too well if you own one of our steel frames, it’s very important to grease your seatpost every couple of months (reminder: go and do that now!). 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. Long story short, 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 standards that we're known for.
