Seem well made. I carry them in my bag for emergencies. ### ⭐ 1.0 out of 5 stars This is only a screw on extender *by T***T on Reviewed in the United States πŸ‡ΊπŸ‡Έ on November 6, 2019* Do not buy this if you are looking for a valve extender the goes into your removed presta valve... these will not work. The pictures are highly misleading. Because of the design, they do not allow the presta valve to fully engage, so your tire will deflate. I'd send them back but they aren't worth the effort. ### ⭐ 1.0 out of 5 stars Incorrect width and thread pitch for presta valves *by B***W on Reviewed in the United States πŸ‡ΊπŸ‡Έ on November 9, 2019* Do not buy these. I do not know what valves these are made for, but I do know that they are NOT for presta. The threads and diameter are all wrong. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/74391857-aurora-racing-5set-presta-valve-extension-black-bicycle-wheel-aluminium](https://www.desertcart.hr/products/74391857-aurora-racing-5set-presta-valve-extension-black-bicycle-wheel-aluminium) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-24*
