Description
2021 Chromag Monk Dirt Jumper – Black (Long)
Chromag’s classic 26″ chromoly dirt jumper.
The Monk features their unique stainless steel horizontal dropout system for minimal complications with single-speed/disc brake setup. Their custom chain stays paired with dedicated DJ geometry offer you a light and incredibly stiff rear triangle on a low slung steel weapon.
The Monk now features their chain tug integrated into the dropout on both sides. For 2020 Chromag is featuring a signature colourway designed by Chromag shredder and all-round nice guy Marcel Hunt.
FRAME SPECS:
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 they’ve always made a point of taking the time to do something interesting with it. Their 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.
