Quick delivery with good packaging. ### ⭐⭐⭐⭐⭐ Fits my bike and works well. No issue *by P***R on 7 April 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 ## 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.sn/products/451057977-continental-race-28-700x20-25c-bicycle-inner-tubes-42mm-long](https://www.desertcart.sn/products/451057977-continental-race-28-700x20-25c-bicycle-inner-tubes-42mm-long) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-24*
