Specialized produces a lot of proprietary parts for our bikes that require a certain level of expertise and knowledge to install. These parts are not available for purchase directly from us. The way to order technical parts is by having your local dealer contact their service parts/warranty rep. to set up a special order for you. There are a couple reasons why we operate this way:
1.) Most of the time, these special parts are not in high enough demand for the local shop to keep them in stock.
2.) Usually you need a mechanic to install the technical parts.
3.) Since they are not identified as "Retail" parts, we are limited to selling them through the appropriate channels.
As always, if you have any questions, feel free to contact Specialized Customer Service at (877)808-8154
