Valve Extenders for tubular tires

Let's Build Your Dream Wheel!


Calculated at checkout


If you are getting a set of deeper carbon tubular wheels it is very likely that your tubular tire will not have a valve stem long enough to inflate them without using a valve extender. With these tubular valve extenders from Boyd Cycling, you can ensure that you will be able to inflate your tires and roll off on your new wheels. 

Tubular tires have a removeable valve core, with these valve extenders you have access to the valve on the outside of the rim. This means you never have to deal with screwing and unscrewing valve extenders and you can ride with your valve in the closed position. You must remove the valve core from the tire, thread the valve extender into where the valve core was, and then screw the valve core back on the end of the valve extender.
These valve extenders will NOT work with Vittoria tubular tires. The Vittoria tubular tires have a valve that unscrews at the base of the tire and you can only use Vittoria branded valve extenders with them.

These valve extenders MUST be installed before gluing the tire in place. There is no way to install these once your tire is already glued!

For 44mm tubulars choose the 30mm length
For 60mm tubulars choose the 50mm length
For 90mm tubulars choose the 70mm length

These will NOT work on clincher inner tubes, unless they have a removeable valve core (most do not).
