Specialized S-Works Stumpjumper EVO Frameset

By pairing a 29-inch front wheel with a 27.5-inch rear wheel, the bike gains significant maneuverability and clearance in the rear. This setup makes it easier to flick the bike through tight corners and steep, technical sections without the rear tire buzzing your backside, while the larger front wheel maintains rollover capability.

The frame features six distinct geometry settings, allowing you to independently adjust the head tube angle and bottom bracket height. This lets you tailor the bike's handling to match your local trails, whether you prefer a slacker, more stable feel for steep descents or a higher, steeper setup for more technical climbing.

Yes, the integrated SWAT door in the downtube is highly practical. It provides a secure, rattle-free space to stash trail essentials like a tube, pump, or light jacket, effectively removing the need for a heavy pack on shorter rides.

Rider-First Engineered means Specialized tunes the carbon layup and stiffness characteristics specifically for each frame size. This ensures that a smaller rider on an S1 frame experiences the same handling and ride quality as a larger rider on an S6, preventing the bike from feeling too stiff or too flexy based on your height.

The frame uses a threaded bottom bracket, which is a standard and reliable choice. However, note that it requires a 38.6mm seatpost diameter, so you will need to ensure your dropper post is compatible or use the appropriate shim.

The kinematics on this EVO model are specifically tuned to balance plush bump absorption with pedaling efficiency. While it is built for aggressive descending, the anti-squat characteristics are refined to keep the suspension stable and efficient when you are pedaling uphill.
