Often times carbon gets all of the attention but as our Senior Advanced R&D Engineer Chuck Teixeira says If you havent ridden an aluminium bike lately you havent ridden an aluminium bike. And with its DAluisio Smartweld frame the Chisel Expert with two-by gearing is no exception.
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. DAluisio (DSW) however allows us to move the joint away from the area of the highest stress making for a lighter frameset thats stiff compliant and incredibly strong—the optimal characteristics of a hardtail XC rig. So what does this mean for you? Youll be powering up climbs shredding singletrack and everything in between on a bike that has you questioning why alloys gotten such a bad rap.
And to further improve this feel the Chisel also features our XC geometry which took our 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 doesnt require any sacrifice of climbing proficiency.
The build on this Chisel features a SRAM NX Eagle 12-speed drivetrain powerful SRAM Level TL hydraulic disc brakes and 25-millimetre-wide alloy wheels that are optimized for weight and traction.
- Given its lightweight and ultra-stiff characteristics M5 aluminium was the natural choice for the frames construction. And when complemented with our speed-focused XC 29 Geometry DAluisio 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.
- SRAMs 12-speed NX Eagle groupset with its 11-50t cassette provides a wide gear range that lets you spin up the climbs yet have plenty of top end for the descents. One-by setups also decrease weight and make it next to impossible to drop a chain.
