As road bike riding diversifies towards multiple road surfaces such as adventure and off-road riding Shimano introduces Ultegra RX, an off-shoot of Ultegra, with a chain stabilizing rear derailleur (RD-RX800\/RX805) for its mechanical and electronic drivetrains.<\/p>\n

Riders have been pushing the limits of what a road bike is capable of riding for many years, evolving the sport from racing to encompass greater adventure. In recent years we\u2019ve seen a broader definition of what a drop handlebar bike can look like; road wheels followed that by accommodating wider tyres. Now in a natural evolutionary step, it\u2019s time for drivetrains to evolve too.<\/p>\n

The new RX800\/805 rear derailleurs share many characteristics with the Ultegra R8000\/R8050 derailleur, such as precise accurate shifting and SHIMANO SHADOW RD derailleur positioning, but with the added chain stabilizing switch (known as SHIMANO SHADOW RD+ technology) to control the drivetrain over rough\/uneven ground or off-road surfaces. Much like Shimano\u2019s MTB derailleurs, the On\/Off switch can be found next to the upper pulley. When activated the rear derailleur pivot takes a firm hold to reduce excessive movement, noise and general \u2018chain chatter\u2019.<\/p>\n

The RX800\/805 rear derailleurs are compatible with Shimano\u2019s road dual control levers (mechanical or electronic shifting) and will accommodate cassettes with low gears from 28T to 34T, making them a very necessary addition for all types of adventure and off-road riding including cyclocross and compact styles with 46T-36T up to 50T-34T chainrings.<\/p>\n

Alongside the Ultegra RX rear derailleur comes a new wider rim 700c, E-Thru axle, tubeless-ready, disc-specific, WH-RS370-TL aluminium wheelset for 28-38c tyres (weight 1900\/pair).<\/p>\n

Consumers can expect the new components to be available in stores from mid-June 2018 onwards.<\/p>\n","protected":false},"excerpt":{"rendered":"
