Almost all Chromag frames are made from quality 4130 chromoly steel tubing. Chromoly is an abbreviation for chromium-molybdenum indicating the materials that the steel is alloyed with.

The added chromium helps increase the steels hardenability and also provide some corrosion resistance.
The molybdenum helps to increase the toughness of the steel.

It has a high tensile strength but is also malleable which is what gives our frames their notorious ride quality and feel. Chromoly is often used when more strength is required than that of mild carbon steel.

It falls under the AISI (American Iron & Steel Institute) 41XX designations which is where the “41” comes from. The “30” indicates it contains approximately 0.30% carbon by weight.

Chromoly is much stronger than traditional 1020 steel and it has a higher strength to weight ratio and high tensile strength, which means we can use less material and achieve a product that can withstand the abuse that riders love to throw at it.

Head Tube Badge

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.

Chromag Headtube Badge


As 12mm through axles have proven to be solid, reliable and convenient, we have committed most of our models to utilize this format.   Our 12mm dropouts are accurate and tough and feature a removable derailleur hanger with a sturdy interface for strength and reliability.  All 2017 models (excluding Monk and Nice Dreams) will follow the 148mm boost spacing.

Our ‘Yokel’ design is a small machined junction on the chainstay that helps accommodate both tire clearance and chainring clearance. Our first versions were huge CNC yokes that bridged the entire front end of the chainstays. Over time we refined this to minimize weight by arranging our chainstay layout asymmetrically and reducing the yoke to a minimal size. It’s one of our most unique frame features and has been copied by other frame makers.

Chain Stay Protector

All Chromags now ship with our injection moulded chain stay protector to help keep the paint fresh and the noise low. These have an adhesive applied, but also slot for zip ties if they come unstuck years down the line, or if you want to apply it to another frame.

Ride One!!!

Always wanted a steel Hardtail. Being a Hardtail fan for years, I have ALWAYS had the desire to get one of these. Steel IS Real, and the team at Chromag knows how to make one heck of a hardcore Hardtail. The way this rides is different than anything I have ridden before from years of owning aluminum and carbon. Love my new Rootdown!!

Amazing hardtail

Just did my first ride and I love this bike! Great geo and handles really well.

Best Hardtail I’ve Ever Ridden!

Title says it all! Love the bike and the customer service when i ordered was amazing, thanks again Dave! I ride predominately on the North Shore and the Rootdown has the geometry to ride just about anything smoothly. Been putting it to the test for the last 4 months and its proven to hold up well, stoked to rip it for many years to come!

Love this bike

I recently upgraded to my second Rootdown, and I couldn't be happier with my decision. Having owned the 2017 model previously, I was pleasantly surprised by the subtle yet impactful refinements in the geometry of the latest version.

The slacker head tube and steeper seat tube contribute significantly to my confidence as a rider. I feel more in control and comfortable when climbing and descending.

Moreover, my experience with Chromag has been nothing short of exceptional. Their professionalism, promptness, and unwavering support have truly set them apart. It's reassuring to know that I'm not just purchasing a bike, but investing in a relationship with a company that values its customers.

I look forward to seeing what Chromag has to offer in another 5-10 years. I will be back for more!!!

Rootdown is Rad

The geo is great the bike is very compliant for a hardtail, handles the chunk better than any other hardtail I've owned. Will be coming back to buy a Monk DJ

This thing rips

I bought this bad boy thinking I’d use it as a second bike to make easier trails more fun when winter keeps us away from gnarlier options. I’ve only ridden fs but once I got used to this it quickly became my go to on double black rides - I’m shocked how capable it is. I’m 5’9” and the M/L is the perfect size.

Downhill monster

I don't know how Chromag have built a Hardtail that makes me more confident and faster on the Whistler trails than my Full suspension enduro rig.

It's got awesome geometry for descending and climbing and just stays super stable, i ride with mu buddies all on full enduro rigs and keep up even on the Blacks.
The only reason I'll stop riding this bike is if i buy the Chromag Lowdown.

Rootdown Sizing

Note: This is an approximate guide, some people have longer legs than others! Feel free to contact us to discuss.
If you're between sizes, it's a good idea to try to ride them both, either by hopping on a demo or stealing from a close friend.
If that isn't an option, examine reach, stack and ETT numbers on your current bike and compare.
