The Continental Grand Prix TR is the tubeless-ready version of Continental's Grand Prix training tyre. It suits riders who want tubeless convenience and durability for everyday miles without paying race-tyre prices. The tubeless casing lets you run lower pressures for comfort and grip, and seals small punctures as they happen so most thorns and glass cuts never end your ride. A puncture-protection breaker sits under the tread for cut resistance, and the compound is chosen for mileage and wet grip rather than outright speed. It is a sensible choice for winter bikes, commuters and training wheels. Key features Tubeless-ready construction Puncture-protection breaker under the tread Compound tuned for durability and wet grip Folding bead Available in multiple widths Needs sealant and a tubeless-compatible rim. We can set these up in the workshop. Check the exact model designation against your rim's requirements before fitting.
