6.5.1 Combined Derailleur/Hub Gears - How They Work and
How to Use Them.
With a Shimano Intego gear system you can shift through the gears
of the speed hub with the shifter and lever on the left side.
The thumb of your right hand switches the 8-speed derailleur gear. On
both sides the big shifters are for the higher (heavier) gears.
With the SRAM Dual Drive (a) both shifters are with one hand. The
slide shifter is operated with the thumb to choose a primary transmission
for the terrain you are riding on. To change this gear, stop pedalling for a
moment without moving the pedals.
The SRAM Dual Drive 27 speed is also available with two sepa-
rate trigger shifters!
The twist grip is to switch through the gears of the derailleur gear. To do
so, please continue pedalling with reduced power.
6.5.2 Readjusting.
The speed hub of the combined gear system is adjusted, as described
in chapter “Multi-Speed Hubs (Internal Gear Hubs)”, the derailleur
gears as described in chapters “Derailleur Gears” and “Rear Derail-
leur”.
Regularly check the reliable t of the bolted connection of the
hub torque arm to the frame (b).
6.6 Crank System.
The SRAM Hammerschmidt (c+d) allows two different gear ratios.
Shifting is performed with a trigger shifter on the left side. Pressing the
big thumb shifter makes for a lower gear ratio.
