New mid-level 105 R7100 mechanical groupset costs under £1,000 and plugs a gap in Shimano’s range – but there are still no rim brakes

Although Shimano 105 R7100 Di2 has been very well received, many riders were disappointed last year when the Japanese giant's everyman lineup became Di2 and disc brake-only. It also left a gaping hole in the middle of Shimano's range between 12-speed and electronic 105 and 10-speed and mechanical Tiagra.Shimano has now officially announced what has long been suspected – that there’s to be a version with mechanical shifting, although rim brakes remain off the menu.

Also like the previous generation, the FD-R7100 front derailleur features what Shimano describes as a toggle-link construction with an integrated cable tensioner. “This is the result of optimised drivetrain components, including 11-34T and 11-36T cassette options, while the FC-R7100 Hollowtech II 12-speed cranksets have 50-34T and 52-36T chainring options.

The new 105 Mechanical shift/brake levers are a slightly different shape from the existing ST-R7170 Di2 Dual Control Levers. The hood is more rounded, for example, and there’s a more pronounced bump in the brake lever – as with the previous generation 11-speed Shimano 105.
