To adjust the Sram Spectro T3 gear hub the shifter must be set to
position “3”. Then move the pedals to make sure that the hub has
engaged the correct gear (fig. 58).
Now push the locating sleeve (H) onto the small pull rod (T)
until the gear cable is taut. Make sure that you don’t pull the
indicator chain out of the deflection pulley (R) (fig. 59). To check
the adjustment: set the shifter to gear position “1” while moving
the crank. If the adjustment too loose: in first gear the indicator
chain can be pulled further out of the deflection pulley by hand.
If the adjustment too tight: it is difficult to set the shifter to gear
position “1”.
The Sram Spectro R5 gear hubs are constructed in such a way
that readjustment is not necessary when the wheel has been
adjusted or removed. The only thing you need to ensure is that
the bolt that attaches the gear-shift unit to the hub axle is located
in the groove in the axle (B in fig. 60). If for some reason it is
necessary to readjust the Spectro gear hub, the twist grip should
be set to the right gear first. This is third gear for a 5-speed hub
and fourth gear for a 7-speed hub.
Subsequently, move the pedals briefly up and down so as to be
sure that the hub has engaged the correct gear. Then turn the
adjuster on the clickbox until the markers visible in the clickbox
window are in line with one another (C in fig. 60).
The following adjustment procedure applies to the Shimano
Nexus 3-speed hub: first set the twist grip to second gear. Briefly
move the pedals up and down so as to be sure that the hub has
definitely engaged the second gear. Then check if the yellow
marker on the gear-shift unit is between the two yellow lines. If
this is not the case, turn the adjusting screw (A) on the gear-shift
unit or the shifter (fig. 61).
For Shimano’s 4, 7 and 8-speed Nexus gear hubs adjustment
must take place in fourth gear (fig. 62). In this case, two red
markers should be aligned with one another by turning nut (A)
(figs. 63 and 64).
