The latest version of Specialized's Stumpjumper Evo trail bike has been on the market for about a year now but, up until this point, the platform was only available with a carbon frame. That's not a problem if you can pay the extra price for a more advanced and lightweight bike, but not so for budget riders. 

Today, Specialized has announced that they will be offering the aggro version of its best trail bike with alloy frames. The Stumpjumper Evo alloy will be available in both Elite and Comp build packages. 

For the alloy frames themselves, the Californian brand says that three separate machining processes were required to accommodate the adjustable headset feature. The downtube is hydroformed and includes Specialized's SWAT box storage system. 

The alloy versions have identical features to its carbon siblings, including an adjustable headset that can be tuned between 63- and 65.5-degrees, plus the bottom bracket height can be tuned by 7mm in either direction. For fans of the mullet wheel size setup, an aftermarket link allows riders to swap the rear 29-inch wheel with a 27.5-inch hoop. 

The Evo's 160mm of front and 150mm of rear travel are given an Rx shock tune, which is specific to the bikes' kinematics and intended use. Specialized says this gives the bike a balance of plush small bump sensitivity, a supportive mid-stroke, and encompassing full travel control.

The Elite model will cost $5,600 / £4,500 and uses Fox Factory suspension. SRAM's GX Eagle drivetrain is combined with Code RS four-piston brakes and 200mm rotors. Roval Traverse alloy rims will roll on Roval/DT Swiss hubs and 2.3in Specialized brand tires. The dropper post is provided by OneUp, ranging in stroke from 120 to 210mm, depending on frame size.

The relatively lower-end Comp version of the bike will cost $3,800 / £3,250 and use a Fox Float X Performance shock and Fox Float 36 Rhythm fork. The model gets SRAM Code R brakes along with a full SRAM NX Eagle groupset. Butcher and Eliminator front and rear tires roll on Specialized 29 alloy rims. X-Fusion has specced its Manic dropper post, ranging in stroke from 100-190mm.

The cheapest Stumpjumper Evo carbon version starts at $5,000 / £3,900 so the alloy version can save more than $1000. Plus, the Elite alloy model gets premium suspension at a cheaper cost than the carbon models.
