Product Usage Instructions:

Geometry:

The Minor Threat bike comes in three sizes: S1 (24″), S2 (26″),
and S3 (27.5″). Each size is designed to accommodate riders of
different heights. Refer to the provided geometry chart to select
the appropriate size based on your height.

Build Options:

The bike comes with various build options depending on the size
you choose. Components such as fork, shock, stem, handlebar,
crankset, brakes, wheels, tires, and more are specified for each
size variant (S1, S2, S3). Ensure the components match the selected
bike size for optimal performance.

Suspension Setup – Sag:

Before setting sag, make sure the dampers (rebound and
compression) are set to full open positions. Adjust the pressure as
needed and bounce on the bike to equalize the chambers. Stand in
your riding position and measure the sag. Repeat and adjust until
you achieve the desired sag level for optimal suspension
performance.

FAQ:

Q: Can I use different components than the ones specified in

the build options?

A: While we recommend using the specified components for best
performance, you can customize your bike with compatible parts as
long as they fit the frame and maintain proper functionality.

Q: How do I choose the right size for my child/adult?

A: Refer to the geometry chart provided for each size variant
(S1, S2, S3) to determine the suitable size based on the rider’s
height. Selecting the correct size ensures a comfortable and
efficient riding experience.

Q: What is the warranty on the frame?

A: For warranty information and registration, please visit

The Minor Threat (now in it’s second iteration) brings some refinement and evolution to the ever-popular kid’s machine, which also happened to be the first full suspension bike we ever launched.

The MTV2 now uses a seat tube pivoting rocker link, which brings it more in line with our other suspended bikes like the Darco and Lowdown. The rocker design allows us to tune the progressivity for older (heavier) riders who are bigger, stronger and are pushing harder.
It also creates enough room in the front triangle to house a water bottle, even on the smallest 24″ model.

The most notable improvements on the V2 are the new 27.5″ (S3) size and ample room for a bottle on all models.

We spec’d the Minor Threat just as we would for the adults. Rock Shox suspension, Maxxis tires and Eagle drivetrains are some of the highlights. Not to mention, we decked it out with Chromag kit for the finishing touches.

Perhaps most excitingly, we’ve now introduced a 27.5″ option into the mix which not only keeps some of the taller kids happy, but maybe even some of the shorter adults among us as well.

SUSPENSION SETUP – SAG

10/17

Suspension sag is the percentage of full travel that the suspension compresses when the rider, including gear, is on the bicycle in a normal riding position. Setting the correct sag allows the suspension to perform effectively. More sag (less pressure) increases bump sensitivity and suspension movement. More bump sensitivity results in a smoother ride and is typically preferred on longer travel bicycles. Less sag (more pressure) decreases bump sensitivity and suspension movement. Less bump sensitivity results in a more firm, efficient ride and is typically preferred on shorter travel bicycles. On RockShox suspension, the sag indication is marked on the stanchion making it very easy to check. If your suspension is from another manufacturer then you will need to measure the sag against the full stroke to calculate the percentage of sag.
Before setting sag, set the dampers (rebound and compression) to the full open positions. Rotate the adjusters counter-clockwise until they stop. After changing pressure, bounce on the bike at least 5 times to make sure the positive and negative chambers are equalized. Stand in your neutral riding position and have your butler read the amount of sag. Repeat and adjust as needed to achieve desired sag.
For more information visit trailhead.rockshox.com or your suspension manufacturer’s website. It should go without saying that suspension setup is an iterative and delicate process. If you are having trouble, or if any of the above seems like a foreign language, please visit your local bike shop for help with setup!

For your Minor Threat, we recommend:
· Fork: 15 – 20% of sag (22.5 – 30mm for 150mm travel) · Shock: 25 – 32% of sag (9 – 14.4mm for 45mm stroke)

25 – 32%

15 – 20%

BUILDING YOUR BIKE

11/17

Whether you get your bike in a box, or roll it out the front door here at Chromag HQ, you can rest assured your bike has been pored over with pride, and built with the utmost attention to detail by one of our extremely talented mechanics. Threads are chased, seat tubes are reamed, head tubes are honed, fits are checked and checked again, all to make sure when you get your bike, everything is absolutely dialed.
If we shipped your bicycle, the only difference is that once built, we disassembled some of the parts to fit it in the box. In terms of assembly, here’s what’s been done, and what needs to be done if you’re getting your Chromag shipped.
What has been done:
9 Chain length adjusted. 9 Gears adjusted. 9 Brakes set up and bled. 9 Handlebar tightened to 6Nm. 9 Grips tight on handlebar. 9 Crankset tight, bottom bracket tight/adjusted. 9 Saddle and seatpost tight. 9 Seatpost greased *make sure to re-grease every 6 months! 9 Tire sealant installed. 9 Cassette tight.

What needs to be done: Inflate tires to desired pressure. 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!
Notes: We recommend using an experienced and qualified mechanic to build your bike. Things bed-in over time, be sure to perform a bolt check after your first ride. (It’s good practice to perform a bolt check before every ride.)
