Cross-country (XC) racing has evolved. The courses are faster and more technical, and the competition is stronger and tougher. Meet the all-new Doctrine, the ultimate hardtail race machine. It’s lighter and stiffer than anything that’s come before it, and its efficienct geometry makes it climb quicker, handle better, and descend with greater control than any hardtail you’ve ever experienced. XC has evolved. So, too, has the ultimate XC weapon.


The new Doctrine is 60 grams lighter than its predecessor. Not only that, but the frame is also 12% stiffer. It’s a staggering achievement from which racers will reap enormous benefits, including quicker acceleration, enhanced climbing ability, and faster lap times.


Nothing comes close to the thrill of victory. That’s why we developed the Doctrine, a no-holds-barred, race day, XC slayer. Super light and stiff enough to make your jaw drop, the Doctrine is the most efficient hardtail on the racecourse. Its perfectly balanced geometry keeps you in total control over the rockiest terrain and down the steepest drops. It’s purpose-built to get you to the top step of the podium.


The Doctrine boasts a mind-bogglingly high stiffness-to-weight ratio, thanks to Felt’s decades of experience in carbon fiber innovation. But more than that, its greatest asset lies in its perfectly tuned ride quality. The rear triangle features a precise level of suppleness that mitigates the impact of small bumps while keeping the rear end firmly planted for maximum traction. This gives the Doctrine the unmistakable liveliness and low weight of a hardtail, but with enough rear-end damping to rival the plushness of many competing full-suspension race rigs.


Based on feedback from the world’s fastest racers, the new Doctrine features an impeccably efficient geometry. A steep seat angle puts the rider into a more forward position to increase climbing prowess. A slacker head angle provides more control for faster descending. Shorter chainstays give the bike a livelier feel for incredibly agile handling for tackling technical terrain and flowy descents.

Improved Tire Clearance

Today’s racers will utilize the best equipment possible for any given event, and that includes selecting the optimal tire for race day or a killer training ride. The new Doctrine has room for up to 2.35 tires, giving its rider more options than ever before, whether the day calls for fast and loose, or loamy and flowy.

Clever Cable Management

The Doctrine features Felt’s most advanced cable routing system, and it’s compatible with every contemporary drivetrain on the market. Electronic wiring or mechanical shift cables, and even lines for dropper posts, all have their place for easy adjustments, maintenance and functionality. Internal routing options provide protection from the elements and clean aesthetics, too.

BB92 Bottom Bracket

There are more bottom bracket standards on the market than you can shake a stick at. So why does the all-new Doctrine feature BB92? Simply put, it’s the best for straight-line speed, lightning quick accelerations, and ensuring that every watt of rider power is used to its fullest.

Boost Spacing

Because the modern XC racecourse is more challenging than all that came before it, and the level of competition is faster than ever, racers are demanding more from their equipment. Enter Boost hub spacing, the modern standard for high-performance wheels. Wider axles make for a stiffer interface for greater traction, control and efficiency.
