We use a pre-authorization payment process for all orders:

Friction drives & conversion kits:

If incompatible, the pre-authorization is released (no charge)

All other products:

Pre-authorization temporarily reserves funds on your card without charging you immediately.

The charge is completed within 24 hours for standard items, or after compatibility confirmation for friction drives and conversion kits.
