The Minor Threat
MATERIAL SELECTION
6066 Aluminum was the best choice for the Minor Threat for a couple of reasons.
Firstly, the use of aluminum allows us to build a bike that’s burly enough to hold up to the bike park without being too heavy for a lighter rider to manage.
Another factor is that aluminum is pretty low-maintenance. With chromoly steel it's quite important to grease your seatpost every couple of months. However, this isn’t as much of issue with an aluminum bike. While unpainted steel is not naturally corrosion-resistant, aluminum is! You should still grease your seatpost (and pretty much every component-to-component interface for that matter) with an aluminum bike, but 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.
Now in it's second iteration, the MTV2 is a finely tuned ride.
key features
Your bike is special. The head tube badge is the finishing touch so we’ve always made a point of taking the time to do something interesting with it. Our head tube badges have changed over the years and are an indication of the time each bike was made.
Whether it’s a cast bronze, or polished stainless steel, water cut aluminum or a 3D CNC carving, each one represents our commitment to detail.
Like all our products, the Lowdown was designed with durability and serviceability in mind. The main pivot uses an expanding collet axle system, designed to avoid over-preload and over-constraint of bearings. This results in a main pivot that spins smoother, for longer.
All pivots spin on Enduro MAX bearings that are well-sealed, long-lasting, and commonly available through most local bike shops or as kits on our website. The pivot hardware is machined from high-strength 7075 aluminum, and the custom-drawn tubing is made from the same 4130 chromoly steel you’ve come to know on our hardtails.
Simple and intuitive.
With no hidden hardware, sliders, or concentric multi-link pivots, every pivot can be accessed, bolt-checked, and worked on without taking the whole bike apart.
Frames are assembled with plenty of grease, and each one is checked over by one of our mechanics before leaving Chromag HQ.
Designed with longevity in mind, all of our kids bikes have a full range of spares available for when it's ridden hard and put away wet.
Suspension designed, tuned and honed in the Sea to Sky.
suspension kinematics
We chose a 4-bar suspension layout for the V2, with a main pivot located just above the bottom bracket, a seattube-mounted rocker link, and a vertically oriented, trunnion-mounted shock. We found this layout to strike a good balance of tuneability, ride quality, and elegant simplicity. A 4-bar layout offered enough tuning parameters for us to design the suspension characteristics the way we wanted them, simultaneously achieving our targets for leverage ratio, progression, anti-squat, and anti-rise.
At the same time, it keeps things simple and intuitive. With no hidden hardware, sliders, or concentric multi-link pivots, every pivot can be accessed, bolt-checked, and worked on without taking the whole bike apart.
Predictable and dependable.
geometry
The Minor Threat continues our geometry philosophy in a kids format. With a low stand over, stable angles and wheelbase the Minor Threat encourages progression.

THIS IS AN APPROXIMATE GUIDE, SOME PEOPLE HAVE LONGER LEGS THAN OTHERS!
Sizing
We decided to make three frame sizes because reach, stack and wheelbase are a much better assessment of bike fit than wheel size alone.
These bikes are spec'd just as we would for ourselves, so there's no reason smaller adults couldn't ride the S3.
We don't recommend switching the wheel sizes between S1,2 & 3 as you are merely making the bike taller and raising the center of gravity, rather than increasing the actual bike size.

FAQ's
Yes, you can run a ‘piggy back’ style air shock such as a Super Deluxe. We do not recommend fitting a coil shock as the characteristic and easy adjustability of an air shock works better for this bike and the changing size and weight of the rider. Fitting this type of shock will limit and possibly prevent water bottle fitment.
No. The bike is designed for the length and stroke shock we spec. A longer shock (eye to eye or stroke) would create clearance issues (contact) between the tire and seat tube or the shock and front triangle. The 45mm stroke is also the longest available stroke for a 165mm shock fitted.
It is possible to run different sized wheels between the different frame sizes. However the effect of this is often not what the customer is seeking. Changing the wheel size or adding a larger front wheel won’t help it fit your growing child much better. The resale of kid’s bikes are very strong, it is often cheaper and gives a better result to sell and upgrade.
This is what will physically fit:
S1: 24, 26”
S2: 24, 26, 27.5”
S3: 24, 26, 27.5”
Note that fitting a 24” wheel to a S3 would really mess up the geo and make pedal strikes very common. It is not recommended to change wheel size and certainly not by more than one ‘increment’.
There is plenty of room around a Maxxis 2.5 tire.
Yes, there is an ISCG 05 mount for this, the chain line is 52mm (standard boost) which is possible with any good guide.
All bearings are surrounded, where possible, by large flat surfaces making removal and refitting far easier. There is access to the outer race of all bearings so if a bearing inner race comes out leaving the outer behind it is still possible to remove the outer with simple tools. See exploded diagrams in the tech pack for more info.
If you’re not comfortable removing/installing your own bearings, we strongly recommend bringing your bike to a local bike shop. It’s possible to damage your bike beyond repair if you improperly remove/install your bearings. Such damage would not be covered under our warranty policy.
The Darco uses a boost rear end (148mm). As such, the chain line should reflect this, typically 51-54mm or a 3mm offset on the chain ring if running
SRAM.
A 34t will fit with a standard boost chain line.

Not much! You can read in depth about it here, but in short:
• Inflate tires to desired pressure. (Sealant is already installed)
• Install brake rotors, tightening bolts to 6.2Nm.
• Attach derailleur to frame, tightening to 9Nm making sure that the B-tension tab rests properly against the derailleur hanger stop.
• Grease headset bearings, install fork and handlebar, positioning the headset spacers above or below the stem according to rider fit.
• Align handlebar stem, preload headset and tighten stem pinch bolts to 8Nm.
• Install wheels, tighten axles.
• Install chain with quick link.
• Grease pedal threads and install pedals using pedal washers supplied.
• Adjust brakes, shifters, saddle position and height for personal preference.
• Set up suspension.
• Bed-in brakes. (Roll down a gentle gradient dragging one brake at a time. Avoid locking them up.)
• Go ride!
Note: If you had to Google "Nm", or you don't know which way to install your rotors, you should probably get a qualified mechanic to build your bike!
• Chain length adjusted.
• Gears adjusted.
• Brakes set up and bled.
• Handlebar tightened to 6Nm.
• Grips tight on handlebar.
• Crankset tight, bottom bracket tight/adjusted.
• Saddle and seatpost tight.
• Seatpost greased *make sure to re-grease every 6 months!
• Tire sealant installed.
• Cassette tight.
Customer Reviews
I am a rider for CHROMAG, and have the gen 1 version of this bike. I can say without a doubt that this is the best kids bike on the market! From the moment I got on it, the bike was perfection in everyway. The spec, workmanship, attention to detail were all there. It is super versatile, it can climb on those long enduro rides, and comes to life on the gnarliest DH trail, or just shredding bike park. It is FUN to ride!
Amazing bike!
My daughter (10) hated biking. It was dad’s sport. She liked knitting and guinea pigs. Then I got her this bike and a pass for Crank It Up and it all changed. Now she has a normal addiction to air time and tells me if her tire pressure is off by 3psi, asked to cut her handlebars down and change grips and was really picky with her suspension setup and handlebar layout. I guess that is a good thing? Now she is working on her speed so she can graduate to clearing everything on c-more. I think having a proper bike for kids is not a bad thing at all.(pic from O Sin)
My son went from an early rider hellion X24 to this and felt the upgrade immediately. I do have some feedback to better dial in the bike, but I'm sure part of the limitation is the manufacturer offering discounts for speccing more parts on a bike. 1. needs a dropper (technically it says its not to be used as a DH bike so of course it should havea dropper), I managed to fit a 120mm oneup. 2. Cranks are too long. 140 or 145mm would be more suitable. 3. An 10 or 11 speed drivetrain would be sufficient. Still a 5* bike but not its truly dialed for my son to send!

I upgraded from a 24" Hardtail and is so happy with the Chromag Minor Threat S2. I have been able shred this down some Knarly Tech and Flow Blacks, Blues, Greens and around town. It has everything I need to shred and soaks up big hits from jump lines and drops, down the steepest root and rock filled shoots like a dream. I am so happy with the Minor Threat, it does all that while looking good with reliability making sure we ride home every trip.
