Flats tyres aren’t something that spring to mind when you think of a pleasant family bike ride or successful training session. If you’re out of practice, a flat tyre can cost you at least half an hour to repair, along with a lot of sweating and fretting: you have to remove and dismantle the wheel, requiring various tools, and at the end of the day your hands often get dirty. But thankfully there’s a quick solution for these mishaps – the GAADI bicycle tube with two ends. It has taken 1,000 hours to develop the optimal cycling feeling that we can guarantee today. The innovative open-ended bicycle tube makes it possible to change the tube without having to remove the wheel or chain guard in the process.
