I bought an very expensive Schwalbe tire. Schwalbe told me they would gladly have exchangrd it since after installing it I had 3 blowouts in three short rides. The bead was bad. Because I am in the US and Chain Reaction is in the UK, Schwalbe U. S could not honor the warranty. Something to do with taxes They said the exchange should not be a problem with Chain Reaction. Chain Reaction has a very archaic warranty process. I cannot process the warranty from a mobile device. Even though I sent all the correct information and a photo by email, they insist I print out the form, fill it out by hand, somehow magically attach a photo to it, take a picture of the form and send it back to them via email. Wait! I already provided all the info via email. What is their problem. Stay away. Not worth the bad service
