A bicycle transmission is the set of various components that are designed to work together. It is a device capable of multiplying or reducing the rotation speed of the wheel in relation to the rotation speed of the cranks. The system is based on a series of toothed crowns, called sprockets and crowns, and by a mechanism (derailleur) that is able to move the chain from one crown or sprocket to another. The operating principle is simple: through the combination of more or less large chainrings and sprockets, the rotation speed of the wheel is changed with respect to the crank arm. Within this category we find the crankset, which means the set of front crowns and cranks. They can consist of a single crown, two (which is called double) or three (called triple). The chainrings can be integrated into the right crank, as in fixed gear bikes or supermarket walking bikes, or fixed on the crank with special threaded pins. The profile of the teeth is rounded, to "cling" on the chain. When the teeth wear out, the individual crowns can be replaced in the valuable cranks (those that are not integrated). We at Pro-M Store offer the cranksets of a href="https://www.pro-mstore.com/Race-Face-mRAC?filc=67&pr=c">Race Face e Hope industry leaders, which produce resistant, light and functional cranksets. In the category we also find the sprocket set (or cassette) which is the set of rear sprockets, which allow you to vary the ratio. Currently, taking as reference the set of proposals on the market, from city bikes to very special carbon ones, the number of sprockets varies from a minimum of 6 to a maximum of 11. The quantity of sprockets on the cassette denotes the speed of the exchange. Pro-M Store offers sprocket sets of E-Thirteen and Hope , excellent cassettes in terms of quality. Then we find the chain guide, a component that is positioned directly on the MTB frame, instead of the derailleur, to prevent the chain from coming out of the crown teeth during fast and bumpy jumps or descents. Extremely popular in Downhill MTBs (combined with a chain tensioner) and in Enduro, it has also caught on in bikes for Cross Country, Granfondo and Marathon use. This is because a transmission with a single crown requires an always well positioned chain, as a classic derailleur can do in a triple or double crankset. Pro-M offers you chain guide of Specialized , which favors the pedaling efficiency, keeping the chain in place even on rough terrain. Finally we find the bottom bracket in the category, which is one of the most important components of a bicycle. Its role is to allow the transformation of the force impressed on the pedals by the cyclist in rotary motion. Without this component, the very essence of a bicycle would disappear. It is installed at the junction point between the seat tube and the down tube, in a specific housing called the "bottom bracket box". We at Pro-M propose the central movements of Hope , resistant and reliable. Come and discover the vast assortment of transmissions in our store in via Gallarate 108, Milan, or buy them immediately in our e-shop Do not forget that for orders over € 100, shipping is free and guaranteed in 48/72 hours.
