SRAM is an American bicycle component manufacturer producing groupsets for road and mountain bikes.
Originally SRAM only produced gear mechanisms, cassettes and chains for mountain bikes but with the acquisitions of Avid (brake manufacturer) and Truvativ (crank and component manufacturer) they now offer complete SRAM groupsets for both mountain and road bikes.
Although they have been producing mountain bike components for many years, they only entered the road market a few years ago but are already firmly established and have won many major professional road races including the Tour de France. Recently they have also started producing wheelsets for road bikes, no doubt aided by the R&D from another acquisition – the specialist road wheelset manufacturer Zipp.
Components are grouped together into groupsets and differentiated by name with each groupset aimed at differing levels of use and price. They are ranked from highest to lowest as follows.
Components include: bottom bracket; brake callipers; cables; cassette; chain; chainset (cranks and chainrings); combined gear and brake levers (referred to as or ‘Double Tap’ levers); gear mechanisms – often referred to as mechs or derailleurs - for front and rear; and wheels.
