Adjustment
Multi-speed hubs need not be adjusted very often. The adjusting mechanisms are
located at the hubs (a) or at the shifting lever. There are two (red) marks on the hub
which have to be brought into alignment by adjusting the cable.
Read the operating instructions of the gear manufacturer carefully. If you have any
questions, your FELT dealer will be pleased to help you.
Check regularly whether the hub or coaster brake bracket is still firmly
connected to the frame.
Checking the chain tension
In the case of multi-speed or single-speed hubs, e.g. BMX, which are not equipped
with a chain tensioner with spring preload, the drive chain tension must be checked
occasionally, i.e. every 1,000 km, depending on the intensity of use. The amount
of play midway between chainring and sprocket should not be more than two cen-
timetres (b).
Adjusting the chain tension of bikes with adjustable drop outs
For the adjustment of the chain tension you need to release the rear wheel axle
bolts or nuts (c). The bolt of the coaster brake bracket must be released by two
turns, as well.
Then pull the rear wheel to the rear, tighten the chain with the bolts or nuts intended
for this purpose (d) and screw tight again the rear wheel axle on both sides. Check
the chain tension. The amount of vertical play midway between the chainring and
sprocket should not be more than two centimetres.
After the adjustment of the chain tension, finish by tightening the rear wheel axle
bolts with a torque wrench.
Tighten the bolt of the coaster brake bracket to the stipulated torque.
