Barletta Sumo Thorn Proof Tube

Barletta Sumo Thorn Proof Tube — 26 x 4 This thorn-proof 26 x 4 tube is built for delivery work and heavy-use e-bikes. It reduces punctures and downtime, so fleets and regular riders spend less time fixing flats. Ideal for Domino's Stores and other delivery operators that run 26 x 4 tyres on cargo or delivery e-bikes.

Who it suits: e-bike riders, delivery riders, commercial fleets (including Domino's Stores), commuters using 26 x 4 tyres.

• Thorn-proof construction — extra puncture-resistant layer helps prevent common road debris punctures so you stay rolling on deliveries.
• Right size for heavy tyres — designed for 26 x 4 tyres used on cargo/delivery wheels, giving a secure fit and stable ride under load.
• Durable butyl material — long-lasting rubber that handles frequent use and reduced air loss for fewer top-ups between shifts.
• Easy fit — standard inner tube install with standard rims; quick replacement gets a delivery bike back on the road fast.
• Fleet-ready — made for delivery and e-bike duty, helping reduce downtime and maintenance costs for stores like Domino's.
• Local special-order availability — we can source these for your store or fleet; ask your local shop about lead times and quantities.
