After five years of working out the bugs and figuring out how to make the product affordable, Fly Bikes has finally put their Cobra tubes on the market and they will be available worldwide within the next few weeks.

If you are new to the program and haven’t heard about the Cobra tubes yet, the please crawl out from under your rock and listen up… This tube isn’t a circle. It’s a straight line that is said to seam together flawlessly when inflated in your tire. The idea is that you don’t have to remove your wheel to fix a flat, making it much quicker and easier to get back on your bike after a blowout.

Fly says they will have a video up soon about how to install the tube if you run brakes, but claim “If you don´t use a brake, it´s so easy that don´t even need explanation…”
