For EU & UK customers, we ship DDP (Delivered Duty Paid), meaning all customs duties, taxes, and import fees are included in your purchase price. You won't receive any surprise bills from customs or delivery companies.

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

Friction drives & conversion kits:

Your card is pre-authorized at checkout
We verify compatibility within 24 hours
Payment is captured after compatibility confirmation
If incompatible, the pre-authorization is released (no charge)

All other products:

Your card is pre-authorized at checkout
Payment is captured within 24 hours
No compatibility verification needed

You'll receive email confirmation once payment is processed.

Pre-authorization temporarily reserves funds on your card without charging you immediately. This allows us to verify compatibility for technical products and ensure order accuracy before final payment. The charge is completed within 24 hours for standard items, or after compatibility confirmation for friction drives and conversion kits.

We process and ship most orders within 1-3 business days. Special products may require 7-14 days processing time.
