Specialized delivers perhaps the lightest aluminium bike
According to Specialized, the new Chisel is the lightest full-suspension aluminium bike in its class on the market. The frame kit weighs just 2720 grams thanks to a new welding process. It is called D'Aluisio Smartweld and is patented. While traditional aluminium frame constructions connect the tubes with welded seams at the highest load points, Specialized's process relocates these. D'Aluisio Smartweld delivers the highest strength at the lowest weight through the use of hydroformed tube joints. These make it possible to move the joint away from the area of highest stress and create a pit in which the weld bead can lie.
Unique to the Chisel is the one-piece, hydroformed seat tube, in which the pivot point of the bellcrank, the main pivot point and the bottom bracket shell are integrated. In traditional frames, seat tubes are often just a tube with welded-on pivot points and bottom bracket shell.
The D'Aluisio Smartweld process is also designed to provide unprecedented handling and ride characteristics on aluminum bikes. Each tube of the frame has continuously varying wall thicknesses and shapes that provide stiffness, efficiency or comfort where needed.
The Chisel's pedigree can be traced directly back to the Epic 8, Specialized's World Cup race machine. The DNA of the Epic 8, such as the suspension kinematics, the suspension tuned by Ride Dynamics and the progressive geometry, can all be found in the Chisel. What is exciting is that the Chisel has a flex-stay rear triangle, which contributes to the low frame weight. This is possible thanks to a modern aluminium alloy.
The Chisel is available in three versions as well as a frame kit and in five sizes from XS to XL.
