When I started cycling again, a friend told me about the importance of gloves. He was an antique restorer and skilled woodworker. He said that if you come off the bike on tarmac, your natural reaction, mid-air, is to put out your hands to break your fall and save your face, teeth and collar bone. When you do that, the tarmac acts like a very coarse abrasive and planes the skin off your palms. As a result, your hands are pretty much out of action for at least a couple of weeks........inconvenient if you use them to earn a living. I never forgot his advice and always wear gloves.
