Chromag Stylus MX Mountain Bike Frame

The Stylus is a true hardtail bruiser. Versatile, confident, and ready to take on everything from long trail missions to technical, high-impact lines. Built around a 160mm fork with a slack front end and now running a mullet wheel setup (29" front, 27.5" rear), it offers the perfect balance of rollover speed and agility.

A new headtube gusset adds extra strength where it counts, while the 12mm Boost 148 through-axle rear end and Chromag’s signature yokel chainstay provide generous tire clearance. With a compact seattube for low standover and room to slam your post, the Stylus stays out of the way when you need to move around on rough terrain or through DJ lines.

It climbs with purpose, descends with authority, and takes a beating without flinching. The Stylus is built for riders who treat the mountain like a playground.

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 steel's 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.
