100 percent benchmarking
Raising the bar. Redesigning the wheel. Optimizing the genetic code. That was our brief. The result: Load Specific Weave – LSW and Shell Node Concept – SNC. Both technologies are BMC proprietary developments which we have implemented exclusively for the impec.

SNC – Shell-Node-Concept
The Shell Node Concept – SNC guarantees maximum stiffness and stability of the frame joints on the impec. These high-density half-shells are made from a newly developed carbon compound material and are bonded under precision control with the frame tubes during assembly of the frame. The benefit of the SNC half-shell technology lies in its total control over the junctions. This results in absolutely flawless frame joints on the impec.

LSW – Load-Specific-Weave
In this process, the tubes for the frame of the impec are woven first of all from carbon fibers and then in a second step are converted to a highly rigid structure using a special resin compound. The load-specific weaving process is fully automated. This results in absolutely flawless frame tubes

technology

tapered steerer

Tapered head tube

: Tapered head tube - with a minimum increase in weight, a disproportionately higher fork thickness results.

BB30

BB30 interface

BB30 crankset

: With these cranks, the bearings are pressed directly into the frame. The diameter of the axle is 30 mm. The advantages of a BB30 crankset are greater stiffness with a lower total weight.

LSW

Load Specific Weave

This robot-controlled process creates the frame tubes for the impec.

LSW is the name of a complex three-stage process at the end of which is the perfect frame tube. in brief, the three stages are as follows: weaving, resin injection and cutting and from these stages comes a humble, flawless carbon tube that only needs to be lacquered, printed and attached to other equally faultless tubes to make the perfect frame.

SNC

Shell Node Concepte

Shell Node Concept means a high control of the nodepoints through splitting them in two halves.

The Shell Node Concept, the joints at the nodal points of the frame are not one-piece collars but are each made from two half-shells. These half-shells are manufactured from a revolutionary composite compound material, are extremely rigid and yet light, have outstanding shock absorption qualities and can be connected to the frame tubes in the final assembly with absolute control and precision.
