{"id":242,"count":1,"description":"<h1>Bicycle Cranksets and Crankarms<\/h1>\r\n<div><span style=\"font-size: 105%\">The heart of the drivetrain is your crankset; the bicycle's crank arms work together to transform your pedaling power into forward motion for your bike. The term \"<strong>bike cranksets<\/strong>\" is a generic term used to describe many essential parts, including chainrings, bottom brackets, and crank arms.<\/span><\/div>\r\n<div><\/div>\r\n<div>\r\n<h2>Bike cranks<\/h2>\r\n<\/div>\r\n<div><span style=\"font-size: 105%\">Your pedals connect to your crank arms, which are connected to the axle at the bottom of the bracket (often also referred to as \"the spindle\"). The chainrings (or sprockets) connect via a direct articulated support or a spider to your crank arms. So, when you press on the pedals, the chainring and crank arms rotate, creating momentum for your vehicle's rear wheel.<\/span><\/div>\r\n<div><\/div>\r\n<div><span style=\"font-size: 105%\">Chainrings are machinable metal wheels, with evenly spaced teeth around the outer edge that connect to the chain. Modern road bikes have two chainrings, but triple chainring configurations are an alternative. Most mountain bikes today use a single chainring, however, you will still see two-chainring setups.<\/span><\/div>\r\n<div><\/div>\r\n<div><span style=\"font-size: 105%\">Chainrings differ in size and shape. The standard shape is round, but there are other options like oval. The tooth shape can also vary in lx chainrings, typically using narrow or wavy profiles to improve chain retention.<\/span><\/div>\r\n<div><\/div>\r\n<div><span style=\"font-size: 105%\">Crown size is indicated by the amount of teeth. The typical range is 25t up to. The greater the number of teeth in the crown, the harder the bike, however, it is also the faster it will push the bike on the track or on the road.<\/span><\/div>\r\n<div><\/div>\r\n<div><span style=\"font-size: 105%\">The two crank arms, positioned 180 degrees apart from each other, can differ in length, typically in the range from 165 mm to 180 mm, in 2.5 mm increments, to fit cyclists of different sizes. The most commonly used lengths are from 170 mm to 175 mm. Most crank arms are made of <strong>aluminum<\/strong> o<strong> carbon fiber<\/strong>, however, titanium and steel are often used.<\/span><\/div>\r\n<div><\/div>\r\n<div><span style=\"font-size: 105%\">Bottom brackets are used to join the wheels and crowns of the bicycle, allowing the cranks to turn freely. There are a variety of types and sizes of bottom brackets such as BB30 or PF30 threaded and BB86 just to name several. Choosing the right bottom bracket and bike cranksets could be a daunting task.
