The Chisel LTD 29" frame by Specialized - For XC newcomers and advanced riders alike

The Specialized Chisel aluminium frame in a limited edition serves as the basis for an affordable entry-level hardtail as well as a first-class equipped cross-country racer. It scores with an optimal stiffness-to-weight ratio, reliable performance, a modern geometry and is available at a fair price. The Chisel was made using D'Aluisio Smartweld technology and hydroforming, which provides plenty of stability without ratcheting up weight. With its Boost installation dimensions, 68° steering angle, long reach and internal cable routing, this frame is completely up-to-date. A Specialized aluminium seatpost is also included.

Technology:

D'Aluisio Smartweld Technology (DSW)
D'Aluisio Smartweld welding technology, named after its inventor Chris D'Aluisio, is based on so-called hydroforming. Hydroforming is a process that uses hydraulic pressure to shape aluminium. A flange with seam preparation is then formed, which is then welded. This improves accessibility during welding, produces cleaner welds due to more even heat distribution and distributes the jump in stiffness over a larger area. This not only ensures smoother stiffness transitions and lower load peaks, but also contributes to material and weight savings because thinner wall thicknesses can be used. This technology makes it possible to get the best out of aluminium, and to produce frames that are nearly comparable to carbon models in terms of precision and strength, but are naturally much more affordable.
