2018 Chisel Expert 2x
The XC hardtail with added trail DNA.
Specialized's senior Advanced R&D Engineer, Chuck Teixeira, says, "If you haven't ridden an aluminum bike lately, you haven't ridden an aluminum bike."
Traditional welding methods create frame joints by connecting tubes to cylinders, leaving the performance and security of the connection up to the skill of the welder. D'Aluisio (DSW), however, allows us to move the joint away from the area of the highest stress, making for a lighter frameset that's stiff, compliant, and incredibly strong—the optimal characteristics of a hardtail XC rig. So what does this mean for you? You'll be powering up climbs, shredding singletrack, and everything in between on a bike that has you questioning why alloy as gotten such a bad rap.
And to further improve this feel, the Chisel also features XC 29 geometry which took the previous XC race geo and added some trail DNA to the mix. This equates to a longer top tube, a shortened head tube, and a slacked out front end, the result of which is a tremendous increase in downhill stability, plus a wider range of fit. And just as importantly, this doesn't require any sacrifice of climbing proficiency.
The build on this Chisel features a mix of Shimano XT and SLX components, a wide rang of gears that come courtesy of a two-by drivetrain, powerful hydraulic disc brakes, and 25-millimeter-wide alloy wheels that are optimized for weight and traction.
- Given its lightweight and ultra-stiff characteristics, M5 aluminum was the natural choice for the frame's construction. And when complemented with speed-focused XC 29 Geometry, D'Aluisio Smartweld technology, and internal cable routing, you get a bike that compromises nothing in delivering explosive speed, confident handling, and hassle-free maintenance.
- A custom RockShox Reba RL 29 fork offers up 90/100mm of smooth travel (size-specific), while an easily accessible compression and rebound adjusts permit you to customize the feel according to the terrain at hand.
- Shimano controls the 11-speed shifting with SLX shifters and an ultra-crisp and reliable Deore XT M8000 rear derailleur.
