Discontinued Parts

We do our best to make parts that will serve the bicycle building community at large, and that means a lot of inventory.  Because of our size and resources, it can be challenging to keep all our products in stock at all times.  Moving forward, we  have decided to prioritize our best-selling parts and to discontinue those that aren't financially viable due to lack of demand and/or changing industry standards.  Along those lines, we have discontinued our line of stainless steel headtubes because sales are low and we can't find a source for consistently sized material.

If you can't find a part on our webstore that you've ordered in the past, it might be because we no longer make it.  We're still willing to manufacture discontinued parts as a custom order, but minimum quantities and lead times will apply.  Order inquiries should be sent to

As always we appreciate your business, and apologize for any inconvenience.
