For selected regions and projects, ASM Sports Tech can also be approached through an authorised partner network. This creates a more local route into the ownership experience while maintaining the same product direction.
If you are ordering internationally, planning a wider build, or simply prefer a more regional point of contact, dealer access can provide a cleaner route into the ASM Sports Tech product direction.
Selected customers may prefer a more local path into the product programme through an authorised ASM partner.
Wider builds and multi-part upgrade directions can often benefit from a more coordinated route before final order placement.
Whether you proceed directly with ASM Sports Tech or through an authorised partner, the objective remains the same: a more resolved ownership experience.
