So, for this model there are no aluminum or carbon lugs, nor monobloc construction. For the 555, oversized tubes are molded then cut, shaped at the ends in order to be assembled as if they were welded. Welding is replaced by bonding reinforced by carbon strips in order to ensure perfect cohesion of the frame assembly. To optimise frame comfort, Look's engineers have developed a special geometry for the chain and seat stays. The Comfort Concept chainstays present a centre section inversion which is achieved by flattening. This creates an inflection point at the middle if the base and so improves vertical flexibility. At the same time, this shape increases the base horizontally, and improves lateral stiffness. The seat stays are slightly curved in order to encourage the absorption of vibrations and so optimizing comfort. * The 555 is only available as a complete bike.
