The demands of today’s road riders have evolved greatly on recent years, riders now expect better comfort, control and versatility from their road bikes, and apart from wanting as much enjoyment as possible on two wheels, current 105 level riders also expect to see the latest pro level features trickled down from the lighter and also pricier high end models. So step forward to the new Shimano 105 R7000 generation groupset with customizable disc or rim brakes and wider cassette options to help you remain in comfort and control wherever you’re riding.
Shimano’s entry level 11-speed groupset is the 105 and the biggest news for the 105 is the addition of disc brakes to the series line up. New flat-mount BR-R7070 calipers are compatible with ICE TECHNOLOGIES pads and UCI-compliant non-90 degree SM-RT70 rotors (including a new 140mm size) to offer greater cooling efficiencies. Brake operation is handled by new ergonomically shaped Hydraulic dual control levers (ST-R7020), matching the design of Ultegra ST-R8020 levers with a greater range of reach adjustment for different hand sizes. To provide even greater customisability, 105 R7000 offers a version of the dual control brake/gear lever (ST-R7025) to better suit smaller hands by being angled closer to the bar and taking more of an outboard position for better connection and to avoid interference with the handlebar drop during lever operation.
Whether from the rim brake (ST-R7000) or disc brake (ST-R7020/25) lever, gear shifts have been redesigned to offer faster and lighter shifts with a shorter stroke compared to the 105 5800 series. The front derailleur has a compact toggle (pivot) design, better tyre clearance and an integrated cable tension adjustment port (2-mm allen key) removing the need for an in-cable barrel adjuster. The optional long cage rear derailleur (RD-R7000-GS) can accommodate up to an 11-34T cassette and is
designed with a low profile SHIMANO SHADOW RD style to tuck it below the cassette and chainstay.
Updates within the drivetrain include a new mid-compact 52-36T crankset, to add to the 50-34T and 53-39T cranksets, and new 11-30 (CS-R7000) and 10-speed compatible 11-34 cassette (CS-HG700-11) options to better suit gravel, adventure or CX riding. Together with this the inner crank ring has been positioned to reduce the effects of cross chaining or chain drop, better suiting bikes with disc brake criterium racing bikes.
