Great price ### ⭐⭐⭐⭐⭐ Fits my bike and works well. No issue *by on Reviewed in the United States April 7, 2026* Bought this as a spare for my road bike. It's fairly cheap and easy to install. The valves could get worn but I think it's after several years. It's probably a few dollars cheaper buying it online versus at the store ### ⭐⭐⭐⭐⭐ They work *by on Reviewed in the United States March 26, 2026* They seem to be genuine tubes. A bit long of a valve for my rims but they work. One popped during installation because I bit it with the tire lever, but that's my fault. They haven't broken in proper use. ## Frequently Bought Together - Continental Race 28 700x20-25c Bicycle Inner Tubes - 42mm Long Presta Valve - 2 Pack - Continental Ultra Sport III 700x25c Black/Black Folding PureGrip - Pair (2 Tires) --- ## 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.gr/products/426466488-race-28-700-x-20-25c-inner-tubes-42mm-presta](https://www.desertcart.gr/products/426466488-race-28-700-x-20-25c-inner-tubes-42mm-presta) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-30*
