We are a small local bike shop, not some giant e-commerce site.
So... there is no shopping cart, no buy-it-now button, no robots and no customer service call center.
And no free shipping. Shipping and Handling is $7 First Class Mail or $11 Priority Mail in the USA.
Other countries by quote.

Step One: Download the parts list (aka, exploded diagram) for your specific hub from the Sturmey-Archer website.
For older hubs go to Sturmey-Archer Heritage or email us as, we have many vintage diagrams.

Step Two: Order by part number NOT hub model, but include your hub model for reference.
Part numbers are 3 letters followed by 3 numbers. Example: HSA120 (older parts may use a single letter Eample: K407)

Step Three: Email your part numbers and quantities.
We will email you a total and a Paypal payment link. You do NOT have to have an account to use Paypal. We also take checks by mail.
