Continental Race 28 Wide Inner Tube - 60mm Presta Valve (SV)

Sovereign Airtight Integrity: High-Fidelity Vulcanized Butyl Rubber Meets Seamless Unitary Construction, Extended 60mm Presta Valve Clearance, and Removable Threaded Cores

Banish sudden, structural roadside blowouts from your distance loops, eliminate tedious daily air pressure loss from low-grade rubber, and experience the elite dependability trusted by elite peloton mechanics worldwide. The Continental Race 28 Wide Inner Tube (60mm Presta Valve) represents the absolute global benchmark for wide-tire road and endurance gravel inner tubes—specifically engineered to deliver a uniform, high-elasticity barrier that fits perfectly inside modern wide-section rims. Sourcing specialized workshop spares independently from international online storefronts often exposes you to frustrating shipping delays, single-item courier minimums, or unexpected port customs hold-ups at the border. Epic Sports handles all international logistics natively, straight to Nairobi. Fabricated under rigorous mold-vulcanization processes, this 60mm SV tube guarantees absolute pressure retention block after block.

Why the Continental Race 28 Wide Framework Governs the Tire Well:

• Advanced Vulcanized Butyl Rubber Synthesis: Superior pressure retention. Precision-compounded from high-grade butyl rubber molecules, then vulcanized inside proprietary cylindrical molds to ensure a completely seamless, uniform material density that minimizes air migration.
• Optimized Wide Section Casing Architecture: Tailored for modern widths. Seamlessly scales to fill larger internal tire volumes spanning from 25mm up to 32mm width profiles, preventing excessive rubber stretching and wall thinning.
• Extended 60mm Presta Valve Stature Profile: Deeper aerodynamic rim versatility. Outfitted with a sleek 60mm threaded Presta valve (SV) length, allowing you to easily clear modern mid-depth aero carbon hoops and deep-section alloy gravel rims without needing finicky valve extenders.
• Integrated Removable Threaded Valve Cores: Effortless customization. Built with a removable core node, giving you the incredible ability to unthread the brass valve center to pour liquid flat prevention sealants directly inside the tube, or to install deep-aero valve extensions easily.
• Rigorous Factory Airtight Inspection Arrays: 100% flat insurance out of the box. Every single genuine Continental inner tube is inflated, placed inside an inspection chamber, and pressure-tested for a full 24 hours at the factory to guarantee absolute out-of-the-box structural perfection.

Frequently Asked Questions (FAQ) for High-Performance Riders:

What is the functional advantage of Continental's mold-vulcanization method over cheap generic inner tubes?

Choosing high-quality tubes comes down entirely to structural uniformity. Cheap, generic inner tubes are often made by taking a flat strip of rubber, rolling it into a tube, and gluing the edges together, which creates a heavy, uneven seam. Under pressure, that seam becomes a rigid line that resists stretching, causing the rest of the tube to expand unevenly, which leaves thin spots vulnerable to flats. Continental mold-vulcanizes every tube in a fully round, continuous cylindrical mold, ensuring perfectly uniform wall thickness across the entire tube. This method provides superior structural elasticity, handles higher pressures easily, and rolls with less resistance.

Can I use this specific Race 28 Wide tube if my tires are marked 700x35c or larger?

No, this model is custom-mapped for a maximum expansion boundary of 700x32c. While high-grade butyl rubber has excellent elasticity and can technically stretch to fill a larger space, forcing a 32c tube up to a 35c or 38c gravel casing will stretch the rubber walls far too thin. This drastically drops your protection against pinch flats, makes the tube highly vulnerable to small trail thorns, and can cause the base of the valve stem to rip away under high torque loads. If you are riding wide gravel or cyclocross tires, ensure you step up to the dedicated Continental Tour 28 All or gravel tube families instead.
