Stylus 2018


The Stylus features aggressive, low slung geometry built around our most robust chromoly tubeset.  It really is a do everything trail bike that’s incredibly versatile and ready for anything from all day trail riding to big burly lines.  It’s built to climb, descend, jump and do it with authority.   It features our 12mm through-axle dropout system with 148mm Boost hub spacing, our unique yokel chainstay layout offering ample tire clearance for up to 27.5x2.6 and 26 x 3.0.  With a short seattube it has plenty of standover clearance and room to drop the saddle when you need to get it right out of the way.  

Built around a 160mm fork with a slack front end, the Stylus is the choice for riders who tend to favor rough terrain and need a bike that will stand up to plenty of abuse and last through the apocalypse.

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.

Stylus 2018 Sizing

Note: This is an approximate guide, some people have longer legs than others! Feel free to contact us to discuss.
If you're between sizes, it's a good idea to try to ride them both, either by hopping on a demo or stealing from a close friend.
If that isn't an option, examine reach, stack and ETT numbers on your current bike and compare.
