The impec riders are not only looking for the best performance and balanced ride quality, they also want to get the latest technology. Unique technical solutions, Swiss design and precision are fascinating these riders.

Swiss Manufacturing
With the impec, we bring frame manufacturing back to Switzerland. Geographically situated by high-end watch manufacturers and medical engineering companies in Grenchen Switzerland, we built a frame factory that is worlds apart from what the cycling world has seen before.

The impec frame is “handmade by machines”. Robots produce tubes, apply glue and put the frames together in a consistency human beings could never achieve. The Shell Node Concept SNC allows us to control the assembly process better than any other technology.

Tuned Performance
Our tubes are not made from woven fabrics as in conventional carbon frame building. With the LSW (Load Specific Weave) technology we control every single fiber to make sure it is in the right place and at the right angle to achieve the properties we want. The combination of LSW and SNC makes for a stiff frame with astonishing vibration damping that creates the unique ride feel of the impec.

Perfect Fit
With the choice of two different frame fit options and 3 different offset seatposts, everyone will find his perfect position on an impec.

Electronic Shifting integration
Specific frames for Shimano’s Di2 or Campagnolo’s EPS groupsets make the integration of the electronic components as clean as possible.

Shell Node Concepte

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

Construction, material and manufacturing process. These three aspects of the frame joints formed the Gordian knot of the impec which could not be untangled using conventional ideas. Everything seemed to be impossibly connected with each other. Until at some point we had the simple idea of creating the frame joints of the impec in two parts.

A clean cut then led to impec Technology no 2, the Shell Node Concept, where 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.


Load Specific Weave

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

impec Technology No 1 is the Load Specific Weave process - LSW. This robot-controlled process creates the frame tubes for the impec. Each of them is manufactured with absolute precision and made-to-measure according to specification with verifiable accuracy...

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.

The strict use of digital technology results in absolute transparency in Load Specific Weave. To provide for this transparency, each workpiece carrier is equipped with a data matrix which contains all the programs for the different process stages that the frame tubes of the impec pass through. The system gives the various robots their commands and at the same time records all the relevant data for each individual workpiece.



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.

Tapered head tube

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