Ti, Differential Plate Mechanism, hollow cranksĬorrespondences between older groups and current groups are only approximate. The front shifter also works with Sachs 3 x 7 internal-gear hubs. RSX - A lower-priced but well-constructed group with drop-bar brake/shift lever: 7-speed rear indexing, and front indexing for triple chainwheels.RX-100 - Reported to be the same as the 105 group except for finish.Shimano has many trademarks for different quality levels and technological features/gimmicks.****** High end groups often include additional parts, including: headsets, seatposts, pedals, chains, cassettes. A group would usually consist of at least a set of hubs, derailers and controls, a crankset and brakeset, all with the same group model name. Shimano markets most of their parts as 'groups'. While Shimano offers a pretty good selection, they don't have the perfect combination for every rider. For example, to reap the benefits of Hyperglide or Superglide, you need to use one of the specific combinations of sprocket sizes designed to work together. Unfortunately, their pursuit of high performance has been somewhat at the expense of versatility. The first commercially successful 'walkable' clipless shoe/pedal system, using a cleat recessed into the sole of the shoe.Īn earlier product called Cyclebinding ® almost dominated this category in 1984, but delays in production of the special shoes required caused the company to fail. Which have reduced frictional losses and a lighter action than previous designs. These developments did more to improve rear shifting than any change in derailer design in the last 20 years.Ī special shape for chainwheels which reduces knee stress and offers other benefits to some cyclists. Hyperglide and Interactive Glide clusters.Shimano was not the first with a cassette hub, but they did pioneer the placement of the right-side axle bearing outboard of the freewheel mechanism, which virtually eliminated the problem of bent axles, and made possible reliable hubs with 8- and 9- sprocket clusters. were the first practical systems that achieved commercial success. Shimano was not the first to develop indexing, but Shimano's Positron and S.I.S. They achieved this position because they have the most successful research and development program in the industry. This gets them a lot of bad press, because they are perceived as the Goliath of the industry. Shimano has come to dominate the industry, and to have a near monopoly on many parts categories. Shimano is the leading manufacturer of bicycle parts. This page is at an early 'under-construction' stage,īut I am putting it up early because other pages link to it.
