A Monotone 2021 Specialized Stumpjumper EVO in For Test… Soon

The 2021 Specialized Stumpjumper EVO is in for test. We give this all-mountain bike a once over before hitting the trail.

There are countless all-black bikes out there, some more monotone than others. The 2021 Specialized Stumpjumper EVO we recently received takes the monotone game up a few notches, with fully black rims and Fox Performance level suspension components.

This Stumpjumper EVO Comp includes an impressive build at the entry level carbon frame price of $4,100/€4,499. For that outlay, buyers will get a full Shimano SLX drivetrain and complimentary 4-piston brake set, a 160mm Fox Rhythm 36 fork with the GRIP damper, and a DPX2 shock to handle the 150mm rear axle path. This S2 size includes a 125mm X-Fusion dropper post, and it clearly has room for more travel. A set of 30mm Roval alloy rims are shod with the new T9 compound on the front Butcher tire, and the Eliminator rear tire uses the T7 mixed compound for faster rolling performance.

The bike’s head tube angle can be adjusted between three positions by changing the position of the headset.

The Stumpjumper Evo frame is wildly adjustable, with two bottom bracket height options and three head tube angles (HTA) to choose from. In the low and slack setting the size S2 has a 63° HTA, 44mm of bottom bracket drop, 443mm chainstays, a 424mm reach, and a 77.3° seat tube angle. In the steep and high mode its HTA remains fairly slack at 65.5°, while the chainstays shorten up to 438mm, and the reach opens slightly to 427mm. There are numerous ways to configure these settings, and Specialized has a cool online geometry tool to help riders sort out what might work best for their trails and desired ride characteristics.

While there are loads of clean lines and burly tubes to discuss all around this frame, we’ll save those for the final review. Some final elements worth noting on this new bike are the brilliantly cage-mounted multi tool and expanded downtube storage. The downtube SWAT slot includes a roll to keep your pump and snacks quiet, and a 650ml sealed hydration bladder for longer adventures when you don’t want to wear a backpack. On night rides, where hydration might be less of an issue, you could use the bladder to shake a post-ride cocktail.

For the official review I’ll be passing this along to another tester who is a better fit for this size S2 bike. There is an even smaller S1 version of this bike that will undoubtedly allow most riders to find a 2021 Stumpjumper Evo that fits.

Much like the Canadian Shield from Rocky Mountain, the Stumpjumper Evo has a piece of foam preventing trail detritus from building up between the front and rear triangles.
