18.4.1
Back centering-cone mounting
The majority of steel rims can be mounted using this method.
Make sure that the clamping cup is attached to the
quick release nut.
Select the appropriate cone for the size of the tyre
centre hole and slide it with the larger diameter
towards the flange on the threaded shaft.
Slide the tyre onto the threaded shaft. Make sure
that the inside of the rim is in contact with the
flange and the cone.
Slide and lock the quick-release nut with clamping
cup on the threaded shaft. The quick-release nut
should be engaged in the thread by at least three
full turns.
NOTICE:
To protect the rim, use a nylon spacer
between the rim and the clamping cup.
18.4.2
Mounting the cone outside
A tyre should only be fixed using this method if the inside of the rim does not provide a precise
centering fit.
Make sure that the clamping cup is NOT attached to
the quick release nut.
Slide the tyre onto the threaded shaft. Make sure
that the inside of the rim is in contact with the
flange and the cone.
Select the appropriate cone for the tyre centre hole
and slide it onto the threaded shaft with the smaller
diameter towards the flange.
NOTICE:
It is necessary to lift the tyre to insert the
cone into the tyre centre hole to avoid damaging
the thread shaft.
Slide and lock the quick-release nut WITHOUT
clamping cup on the threaded shaft. The quick-
release nut should be engaged in the thread for at
least three full turns.
