Road bike rear mechs should always be chosen to be compatible with the rest of the groupset. Not only because actuation/ratios vary but also because matching gear components produce the best performance. With electrical group sets like Shimanos Di2 or Campas EPS this is obvious. Campagnolo, Shimano and also Sram offer suitable road bike rear derailleurs for your groupsets. From 2015 11-speed has been incorporated in the entry level Shimano 105 and Sram Rival groupset. With the introduction of 11-speed technology, many road cyclists, especially those who are averse to steep climbs have a new choice: Shimano and Sram offer rear mechs for groupsets with long cages, that allow the use of a cassette with up to 32 teeth on the largest sprocket. You will find your new road bike rear derailleur in our range at competitive prices, wether they are Shimano, SRAM or Campagnolo.
