Silca Valve Extender

ENVE partnered with the renowned inflation artisans at Silca to create the dependable Silca Valve Extender. While a valve extender isn't the most glamorous accessory you'll buy for your bike, your ENVE rims will take much less time to inflate without you having to search for a lost valve rattling around. The extenders are compatible with any tubular or non-tubeless clincher rim from ENVE and tubes or tires with removable valve cores. And let's face it — if anyone can design a tiny part that functions the way you need it to, it's Silca.

Not the only one fooled by the photo

I returned this product before using it

Would also like to express my displeasure of being sent a different item than what is pictured in the photo of this product. I've uploaded a picture of what was received. The big difference - and main selling point of the ones pictured above are the gray rubberized middle section that will help in reducing chatter in a deep section carbon wheel. As you can see, the ones sent are smooth and will require some janky electrical tape to quiet down. Anyhow, not happy and now see I am not alone. EDIT - May 29, 2021 - while the promise of a return shipping label and the correct Silca product was offered back on March 29th, after repeated follow up emails, I still have the incorrect product ready to return. If I use the automated return system, I pay for shipping ($6.99 if they produce the label) and thats deducted from the purchase price, which I am not willing to pay for a return of the incorrect product. Edit - was able to get a return label after further follow up

Bait & Switch on the last pair

I've put it through the wringer

Just bought my third set of these. The most recent ones I received are NOT what is pictured with the silicone exterior. This is a key feature as it removes valve vibration on deep carbon rims, and apparently they also make a version now WITHOUT this feature, which is what was sent to me. The product description and photos should be updated. Not stoked on this.

Valve Stem Extenders

These work great. Remove your valve core, screw in the extender, screw in the valve core to the extender and you are ride ready! I'm using these with my 808 carbon wheelset.


From the pic, these look to be threaded. Can you use a locknut to secure the valve stem for tubeless use?

Use these on all my deep dish wheels

Once installed, these extenders do not leak any air when inflating. Best extender on the market

valve extender

This is by far the best valve extender I've ever used!!


the enve valve extenders, pls clarify how they work. do you have to remove the valve core of the valve on the tube and screw it into the top of the valve extender? are they compatible with other rims like the oval 980s?


These are sold as a pair.


Hi! Will this fit any clincher rim valve hole or does Enve have some special valve hole diameter? Thanks!

Hi Todd. It should fit any clincher rim.
