In cycling, the tire-contact patch area is determined by the rider\u2019s weight and your tire pressure. If you got on two different bikes with two different width tires but the same tire pressure on both bikes, the contact patch of the different tires would match because both tires are supporting the same load with the same pressure. The only difference in these two scenarios is the SHAPE of the contact patch. A wider tire will produce a wider and shorter contact patch compared to a narrow tire.<\/p>\n\n\n\n<p>There are two ways to make a tire wider \u2013 get a bigger tire or get a rim with a wider tire bed. Wider rim + wider tire = wider and shorter tire contact patch. This promotes less tire sag, which deforms the tire less, resulting in less energy lost in the rolling tire. Improving rolling resistance has the same magnitude of impact on overall efficiency as choosing the right rim shape.<\/p>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;69ea645fac55d&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"69ea645fac55d\" class=\"wp-block-image size-full wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"908\" height=\"898\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/wp-media.bikehub.co.za\/production\/uploads\/2023\/03\/z_tse_rolling_resistance_v02_1816px.webp\" alt=\"\" class=\"wp-image-62420\" srcset=\"https:\/\/wp-media.bikehub.co.za\/production\/uploads\/2023\/03\/z_tse_rolling_resistance_v02_1816px.webp 908w, https:\/\/wp-media.bikehub.co.za\/production\/uploads\/2023\/03\/z_tse_rolling_resistance_v02_1816px-300x297.webp 300w, https:\/\/wp-media.bikehub.co.za\/production\/uploads\/2023\/03\/z_tse_rolling_resistance_v02_1816px-768x760.webp 768w\" sizes=\"auto, (max-width: 908px) 100vw, 908px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\taria-label=\"Enlarge\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.imageButtonRight\"\n\t\t\tdata-wp-style--top=\"state.imageButtonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Vibration Losses<\/h2>\n\n\n\n<p>Our Solution: Using a new rim laminate, we design Zipp wheels to be versatile: They can be ridden on traditional roads, but they are also capable of tackling harder terrain including rough roads, light gravel, and\u2014of course\u2014the cobbles of the Spring Classics.
