INITIAL and SPIRGRIPS®, the secrets of the original inner bar grip

There’s nothing quite like sports for inspiring innovation. Pascal Badollet, accomplished Geneva-based mountain biker and physiotherapist, certainly agrees.

Since 2014, he’s been working with INITIAL on his SPIRGRIPS® ergonomic grip concept.

Our Design Department helped him to develop and perfect this product, which has proved a real hit with both amateur and professional cyclists. Head behind the scenes of the design of these innovative grips.


With his training as a physiotherapist, the creator’s aim was to design grips capable of offering both an alternative cockpit position and correct forearm articulation alignment. The inner bar grips are fixed to the handlebars, within easy reach, to allow you to enjoy a comfortable position optimising both articular support and muscular performance.

A patented design offering unrivalled full prehension and user comfort.
With its unique ergonomics, the SPIRGRIPS® grip offers perfectly physiological contact points.

The 1st version of the grip was made from aluminium.

After multiple tests under real conditions by professional athletes, a 2nd optimised version was produced. It needed to be lighter, warmer and more functional on the handlebars based on optimal compatibility with the latest brakes on the market. A polymer grip could meet these requirements. INITIAL employed its product design and 3D scanning expertise to perfect this high-tech product.

A model was created based on version 1.

A 3D scan of this model enabled acquisition of the new geometry and guaranteed that the measurements were totally accurate.
A reconstruction and modelling phase saw the grip optimised.

Combining design and ergonomics for perfect on-bike integration and optimal use.

A 3D file featuring all the part’s complex shapes was created.

It will form the basis for the production of prototype parts then the creation of an injection mold.


Following optimisation of the SPIRGRIPS® grip, INITIAL produced a series of 3D-printed prototypes.

More than 40 production machines were set to work to produce the prototype parts all along the process to perfect it.

Made by sintering aluminium-filled and natural polyamide powder (SLS®), the grips were able to successfully pass mechanical resistance tests.

Several iterations were produced to confirm the new grip’s ergonomics through user testing, as well as its perfect on-bike integration.

With its tooling and thermoplastic injection expertise, INITIAL was able to successfully industrialise this project. The part is now thermoplastic injection-molded from composite material. SPIRGRIPS® are on sale in specialist stores.


The invention took the gold medal at the 44th International Exhibition of Inventions of Geneva in 2016.


The SPIRGRIPS® fan community just keeps growing. Users really enjoy the experience and want to let people know: “Try it, you’ll love it”.


SPIRGRIPS® grips have also been approved for use in MTB competitions by the UCI (Union Cycliste Internationale). 2 models are currently available: “Road” and “MTB”.
