Always be prepared with the Jeorge Black Cat 700C Road Bicycle Tube Twin Pack — two premium inner tubes at outstanding value, designed for road cyclists and triathletes who know that a reliable spare can make or break a training ride or race day.
Each Black Cat 700C tube is purpose-built for 700x23/25C tyres with a Presta 48mm valve, making it the ideal choice for road bikes, triathlon setups, and deep-section aero wheels commonly used in racing. The longer 48mm valve stem ensures easy inflation access even with deep-profile rims, providing a secure, airtight seal every time.
Constructed from durable, high-quality rubber, Black Cat tubes deliver excellent air retention and reliable puncture resistance — reducing the risk of flats on training rides, commutes, and race day efforts. The robust construction holds pressure effectively across long distances, giving you the confidence to push hard without worrying about what's happening beneath you.
Lightweight and straightforward to install, these tubes are the perfect addition to your saddle bag, jersey pocket, or race transition kit. Keep one ready to go at all times — because the only thing worse than a puncture is not having a spare when it happens.
Buying as a twin pack means you're always covered — one for the bike bag and one at home, or share with a training partner who's always borrowing yours.
