We\u2019re happy, because we feel the construction of our bike makes sense in way we need to enjoy it. But behind the frame and especially wheel precision mechanics there is even more. How do the professionals call it? Let me introduce you to the\u00a0axial ball bearing. Let\u2019s just take a\u00a0few moments to appreciate this clever little thing.<\/p>\n<p><a href=\"https:\/\/www.youtube.com\/watch?v=ONz6S48QgEk\">https:\/\/www.youtube.com\/watch?v=ONz6S48QgEk<\/a><\/p>\n<h2>Geniuses here and there<\/h2>\n<p>Leonardo da Vinci was a great inventor and he got a hell lot of good ideas. However, his follower Agostino Ramelli was the first to have published sketches of roller and thrust bearings.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-29451\" src=\"http:\/\/beta.welovecycling.com\/wp-content\/uploads\/2015\/10\/DaVinci-bearing.jpg\" alt=\"DaVinci bearing\" width=\"380\" height=\"300\" \/><br \/>\nPhoto:\u00a0Drawing of Leonardo da Vinci, Study of a ball bearing<\/p>\n<p>An issue with ball and roller bearings is that the balls or rollers rub against each other causing additional friction, which can be prevented by enclosing the balls or rollers in a container. Both types\u00a0were described by Galileo in the 17th century.<\/p>\n<h2>Material is essential<\/h2>\n<p>The first plain and rolling-element bearings were wooden, closely followed by bronze, but other metals and plastic are mostly used today. If you have been obsessed by bike\u2019s autopsy you\u2019ve been looking at nylon, polyoxymethylene, polytetrafluoroethylene and UHMWPE. All those technologies have grown up because of fabulous Sven Wingquist, without them the modern, self-aligning designs would be non-existent. The SKF ball-bearing manufacture has been established in 1907, when Wingquist was awarded Swedish patent no. 25406 for its design.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>While you pedal up the hill you usually don\u2019t think about how comprehensive the bike is.
