Primer Anniversary Edition Kameleon M

CHF 4,077 CHF 5,096

In 2023, Chromag turns 20.

To celebrate, we've created a limited run of our Primer frames. Numbered 1-10, and including specially designed 20th Anniversary decals, these bikes are each one of a kind. Every purchaser of an Anniversary Primer will be gifted a full Chromag riding kit, and receive exclusive access to our Friends & Family discount program.

Hand welded in Vancouver by legendary frame builder Chirs Dekerf, who has signed each frame, these bikes are steeped in BC mountain biking history. 

The Primer uses what we would describe as our most progressive 29er geometry to date (excluding the Doctahawk!), notably the short chainstays, lower than ever BB height, steep seattube with a slack head angle, low stack headtube and long front center. This combination is the most versatile 29er we've ever built.

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.

Dropouts

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.

Yokel

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.

quiver killer

Big ups to the Chromag squad! Couldn't be more thrilled with my Primer. The build quality is phenomenal and the geometry has this bike perched at the edge of becoming a quiver killer for me. It seems to do anything I can put my imagination to and still wants more. Very impressed with the customer service, the quality of the build and the fun of the ride. Thanks Chromag!

Custom Paint

Recently bought a Primer frame and I couldn’t be happier. Chromag were immediately in touch with me to start discussing paint ideas. Not only does the frame quality surpass expectation, the service is outstanding. Charlie was very helpful answering any questions I had and never hesitated to add anything to my order. Highly recommend this company

Primer for the win

This bike is nothing but a snappy good time. Great when it gets steep, jumps well, honestly just a blast to ride.

Canadian made magic

Last spring I sold my carbon fibre full suspension bike to buy a Primer and haven’t looked back. This bike is a sweet, sweet machine. The geometry feels just right - the seat tube angle puts you in a perfect climbing position, and the head tube angle combined with a 160mm fork makes the front end feel super stable on the descents. At 5’11’’ the M/L feels perfect for me. One of the most frequent questions I hear from other riders when riding locally on the North shore is whether I feel limited to certain trails. Not at all; this bike can handle pretty much anything I was riding with full suspension. One of my favorite things about the Primer is just being able to forget everything and get back to the pure joy of riding. The build quality and craftsmanship are fantastic, and I love riding a Canadian made frame. If you’re having any doubts about a hardtail, just go ride one, you’ll be an instant convert.

Love my Primer!

Don't know if I should be posting this here or on the Rootdown page. Back in early 2020 I bought a Rootdown, went to start building it, and realized there was no rear brake mount. I reached out to the dealer (Beat Cycles in Lakewood, Ohio - great dudes there fyi), and they got in touch with Chromag. In a couple hours Beat got back to me and told me that Chromag was fresh outta Rootdowns in XL, but they had an XL Primer laying around that they wanted to send me at no extra charge. I took them up on that obviously, and I've been so happy with this bike. It's just pure fun. Chromag made a lifetime customer out of me with the way they took care of my situation.

The bike rules. Climbs like a goat, and the descents will always put a grin on your face. Plus it looks badass.

Built to fly/cheater cheater pumpkin eater

I replaced an older hardtail with the Primer. I have only ever ridden hardtails, but this thing is next level. It has more travel than what I am used to, which feels like cheating on the downhills. Any jumps or potential launches/drops/wall rides feel like I am riding my BMX, and with nice big juicy 29er tires, it feels barely sketchy on any landing. The BB is lower than what I am used to, so for climbing steep walls it took a little getting used too but it pays off. I got a killer paint job so it's a little disco. I mean, you might as well. The build kit is solid. I upgraded a few bits and bobs but kept the fork and drive train. I love that these guys are making stuff in Canada. Way to go! Great customer service too,

Mountain biking is now about 35% more fun than it was before. Thanks!

Primer Anniversary Edition Kameleon M 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.
