Strictly Business

CHF 3,025

If mountain bikes are a tool for pleasure, these two unique gravel bikes are strictly for business use only. Pack your lunch, press your suit and kiss your (wo)man goodbye, Swing your leg over your 1/2 Chromag gravel bike.

The idea for these bikes are the product of some Thursday afternoon beers and a bit of bike related tinkering and experiments at Chromag HQ. Both these hand built chromoly gravel bikes are offered as a special edition only! We have no plans to mass produce these bikes.

Quite possibly the ultimate shredding machine for longer off-road adventurers and gravel grinders: the strictly business. This burly steel mule is built to handle anything you can throw at it, from rocky terrain to steep inclines and everything in between. A beefy 2.4” tire out front leads the way and the dependable steel fork / frame construction with embossed Chromag logo are there to dampen the ride the only way steel knows how.

Geo for these bikes has been designed to follow the Chromag flavor, geo diagrams for the M/L (Green) and the L (Black) are provided in the images.

With its sleek steel frame and beefy tires, this gravel bike is both stylish and rugged. It's a Dirty Martini, a sexy pirate or one of those weird 4x4 Porsches that people seem to be off-roading right now. 

Playtime is over, its time for Strictly Business.

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.

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.
