Riese & Muller Charger4 GT Rohloff

The Rohloff SpeedHub electronic gear system is operated using simple up/down shift buttons to replace the traditional mechanical gearshifters. The gears are contained in a sealed hub, which protects them from mud and rain, making the system extremely resilient. As a GT bike, it also comes with a slightly smaller rim size (27.5") to allow for larger tyres to be fitted as well as an air suspension fork, making the bike more suitable for adventuring offroad.
