Stylus MX Eagle 90

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.

4130

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.

Why we made this

The Stylus has always been our go-to for aggressive, technical riding. Burly enough to get rowdy, responsive enough to make it fun. For this latest evolution, we wanted to push the platform even further into the modern hardtail frontier.

The new Stylus now features mullet wheel compatibility, 29" up front, 27.5" in the back, to blend rollover confidence with snappy handling. Whether you're threading a tight chute, roosting a corner, or charging into the unknown, the mixed wheel setup keeps things fast and playful without compromising control.

We also reinforced the headtube with additional gusseting, giving it even more strength to handle bigger forks and harsher lines. Because let’s face it: if you're riding a Stylus, you’re probably not picking the easy way down.
