Single bolt system
The single bolt seat post standard clamp is designed to interface with
most performance bicycle saddles featuring round 7 mm diameter rails,
including all saddles. Replacement outer clamps are also available to
accommodate ovalized rails of 8 mm height x 8.5 mm width, as well as
carbon saddle rails beyond the 8 x 8.5 mm dimensions. Contact your
WHEELER bicycle dealer if you are uncertain what type of rails your
saddle has or if you require more information.
a
To install the saddle, unscrew the fixing bolt as far as possible
out loosening from the lock nut on the other side of the clamp assembly.
It is generally not necessary to take the mechanism completely apart
if it is already equipped with the correct outer clamps for your saddle.
If you do find it necessary to unscrew the single fixing bolt completely,
proceed to remove it from assembly. This will free up outer clamp piec-
es. Inner clamp pieces are held in position with rubber retention plate
(leave in place). Install saddle rails into inner clamp pieces, add outer
pieces and re-insert fixing bolt.
b
If the width of the saddle rails does not fit exactly into the clamp grooves,
do not try to force them in! This can cause the clamping mechanism or
the saddle rails to break, resulting in a crash and potential injury to the
rider. Use a different model saddle or consult your WHEELER bicycle
dealer for help.
If the saddle rails fit into the seat post clamp grooves, slide the saddle
so that the clamp is positioned midway along the rails' total length.
Then position the saddle so that its upper surface is parallel to the
ground. Turn the bolt gradually and ensure that
c
1) the clamp assembly is still properly mounted on the carbon fiber
2) that the clamp is tightening evenly around each rail (b).
Once there is uniform hold on both rails, tighten the bolt gradually with
a torque wrench
which is listed on the seat post in newton-meters (Nm).
Never exceed the recommended torque, specified on the components.

GEnERAL InFoRMATIon on BRAKES
Brakes
(d+e)
are used to adjust your speed to the surrounding ter-
rain and traffic. In an emergency situation, the brakes must bring the
WHEELER bicycle to a halt as quickly as possible.
In the process of such emergency braking, the rider's weight shifts
abruptly forward, thus reducing the load on the rear wheel. The rate of
deceleration is primarily limited by the danger of the rear wheel losing
contact with the ground, resulting in an overturning of the WHEELER
(a)
with-
bicycle and, secondly, by the grip of the tyres on the road. This problem
becomes particularly acute when riding downhill. Therefore, in case of
an emergency braking situation you must try to put your weight back
and down as far as possible.
Actuate both brakes simultaneously
the weight transfer, the front brakes can generate a far better braking
effect on a surface with good grip.
The braking conditions on unpaved surfaces differ, i.e. overbraking the
front wheel can make the wheel skid. Therefore, be sure to practise
braking on different kinds of surface. Wet weather reduces the brak-
ing power. Actuate the brakes carefully when riding on wet or slip-
pery ground, as the tyres can easily skid. Therefore, reduce your speed
when riding in such conditions.

An improperly adjusted power modulator could result in a
severe accident. Ask your WHEELER bicycle dealer about
the system your WHEELER bicycle is fitted with.

If you want to adjust the power modulator by yourself, then
it is absolutely necessary to read the brake manufacturer's
operating instructions, which you can find on the enclosed
CD. After every adjustment, check the brake in a place free
of traffic to get a feeling for it.
There are various types of brake systems that may be subject to the
following problems:
rim brakes

are liable to overheating as a result of too long braking
or brake dragging. This can damage the inner tube or make the tyre slip
on the rim, causing a sudden loss of air which could lead to a serious
accident in the process.
