เฟรมเสือภูเขา SJ EVO ALLOY FRM ALU/GUN S4

Description of item

The Stumpjumper EVO Alloy is the bike for those who want to tackle hard sections and enjoy serious trail riding. Like its higher-end carbon frame, it features an adjustable head angle, 150mm of trail-tuned travel, S-Sizing for balanced climbing and descents, and a SWAT™ Door for your ride essentials. It's no longer a run-of-the-mill trail bike. These features are combined with a lightweight yet sturdy M5 aluminum alloy frame. So you can blast through the roughest trails you'd be afraid to ride on a DH bike.

■It doesn't matter how much travel you have if you don't use the right suspension kinematics (link design). That's why we designed the new Stumpjumper EVO with cutting-edge technology. Knowledge gained from Enduro suspension design and over 1000 hours of field and lab development not only improves pedaling performance, but also enhances off-road performance, making it agile and nimble. Not only does the anti-squat increase to suppress unnecessary suspension sinking due to pedaling, but it also improves the ability to follow sharp bumps such as rocks and tree roots. The result is a bike that cuts through the trail without sacrificing your leg strength.

■S-Sizing of new Stumpjumper EVO is the most advanced geometry in Specialized. The reach is long, the center of gravity is low, and the head angle is slightly flattened, while the seat angle is slightly raised. And with a short offset fork, a great ride is guaranteed. However, the perfect geometry is different for each rider, so it can be set in 6 different geometries. The BB height is 10mm, and the head tube angle can be changed twice. Finally, for riders who prefer split wheels, the EVO is available with 27.5" wheels in the rear.

■Rider-First Engineered™ frames are designed for each size to achieve a uniform ride across all frame sizes. Therefore, from a small person who rides S1 to a tall person who needs S6, it can run through corners accurately as if it were riding on rails, has excellent front and rear rigidity balance, and maintains lightness as much as possible. You can feel it.

In 2016, we introduced the SWAT™ Door for the first time on a Stumpjumper, allowing you to store ride essentials such as a pump and spare tube in the downtube, eliminating the need for jersey pockets.
