I'd say too big for 20. **Q: The photos show a schrader valve not a presta valve. Can you clarify the valve type and length?** A: The inner tube is available in both valve options with the Presta being a standard 45mm valve though 60mm and 80 mm options are available in presta.Steve **Q: Is the inner core removable and how do I specify the length of the presta valve (a previous answer says there are options)?** A: I think the core is removable. The presta valve needs to clear the rim by approx. 30mm so you can connect the pump on. If you have a pump with the flexi end that screws on, this is not as critical. You need a longer valve if you have wheels with an more aero design. 60mm should cover most applications. Should you have to use the new tube, you can measure the length of the old valve! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable and Durable Tubes for Serious Cyclists *by H***G on 20 July 2024* I used the Continental Race 28 (700c) tire tubes for a while now, and they have proven to be an excellent choice for both my daily commutes and long-distance rides.

Quality control isn't great on these but for the money, I think they are good value. ## Frequently Bought Together - Continental 42mm Presta Valve Tube - Continental Ultra Gatorskin 650x23c --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/48145678-race-28-700c-x-25-32c-presta-valve-inner-tube](https://www.desertcart.vn/products/48145678-race-28-700c-x-25-32c-presta-valve-inner-tube) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-21*
