Check the rear wheel alignment
and correct as necessary using a
19mm (RKR 3+ and Irok+ coaster)
or 15mm spanner (Irok+) to loosen
the rear wheel nuts. Make sure
you re-tighten your rear wheel nuts
prior to riding your RKR BMX. At
the same time ensure you have the
correct chain tension. Irok+ models
use a freewheel and thus the chain
should NOT be as tight as it would
be on a normal BMX with a ‘driver’.
This will significantly slow down
your rear wheels free spin. Please
see photo, the chain should be
slightly loose but not flapping.
Once you are happy that everything
is aligned and the chain tension is
correct, fully tighten down all axle
nuts on the rear wheel.
