Every now and then we throw a special painted frame into the mix. This radioactive neon red primer almost seems luminescent! White decals pop nicely against this color and give a decent waft of retro vibes. Grab this primer now and skip waiting for our next paint run.

The Primer is a bike built for 29 or 27.5+ wheels with geometry designed for aggressive all mountain riding and is handbuilt in Canada by local fabricator Chris Dekerf in small batches.

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.

Building a frame with 27.5+ compatibility means that we had to redesign our ‘yokel’ junction to maximize the chainstay layout clearance. Incorporating a BB92 bb shell and boost dropout spacing also accommodates the most room possible for tire widths as wide as 3.0.

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.

We hand ream PF92 BB shells carefully to a high tolerance and BB cup dimensions from different manufacturers vary. We follow SRAM-Dub specifications and SRAM BB cups are our first recommendation for the most accurate fit. If there is a specific BB/Crank combo you wish to fit to your frame, we can assist in evaluating the fit and even potentially ream and fit the BB for your new frame.

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.
