Where can I buy them?

• Consumers should purchase complete bikes, frames manufactured with BTCs™** and accessory items from a local retailer. If your retailer doesn't carry bicycles with BTCs™ and is unable to work with a listed framebuilder, we suggest you contact a framebuilder to locate a retailer in your area. In areas where a framebuilder isn't represented, they may sell to you direct, but there is usually no price advantage. Some framebuilders don't sell through retailers, they only sell direct to consumers. For information regarding whether a framebuilder sells direct or through retailers, see the builder profile for each framebuilder which can be found by clicking on the framebuilder's name on the **framebuilder lists..
  
• Retrofitting BTCs™** to your existing frame** can be arranged through a retailer but it is more commonly done by going direct to a** framebuilder**.
  
• BTCs™** are sold only to professional bicycle framebuilders. **We're sorry but couplings are not sold to amateur framebuilders.
  
• S and S Machine does not sell bikes or retrofit bikes, we only make the couplings which we sell to professional bicycle framebuilders.
