4. Clipless pedals (sometimes called “step-in pedals”) are another means to keep feet
securely in the correct position for maximum pedalling eciency. They have a plate,
called a “cleat,” on the sole of the shoe, which clicks into a mating spring-loaded
xture on the pedal. They only engage or disengage with a very specic motion
which must be practiced until it becomes instinctive. Clipless pedals require shoes
and cleats which are compatible with the make and model pedal being used. Many
clipless pedals are designed to allow the rider to adjust the amount of force needed
to engage or disengage the foot. Follow the pedal manufacturer’s instructions, or
ask your stockist to show you how to make this adjustment. Use the easiest setting
until engaging and disengaging becomes a reex action, but always make sure that
there is sucient tension to prevent unintended release of your foot from the pedal.
WARNING: Clipless pedals are intended for use with shoes specically made to
t them and are designed to rmly keep the foot engaged with the pedal. Do not
use shoes which do not engage the pedals correctly.
Practice is required to learn to engage and disengage the foot safely. Until
engaging and disengaging the foot becomes a reex action, the technique
requires concentration which can distract your attention and cause you to
lose control and fall. Practice engaging and disengaging clipless pedals in a
place where there are no obstacles, hazards or trac; and be sure to follow
the pedal manufacturer’s setup and service instructions. If you do not have the
manufacturer’s instructions, see your stockist or contact the manufacturer.
F. Bicycle Suspension
Many bikes are equipped with suspension systems. There are many dierent
types of suspension systems — too many to deal with individually here. If your bike
has a suspension system of any kind, be sure to read and follow the suspension
manufacturer’s setup and service instructions.
If you do not have the manufacturer’s instructions, see your stockist or contact the
manufacturer.
WARNING: Failure to maintain, check and properly adjust the suspension system
may result in suspension malfunction, which may cause you to lose control and
fall. If your bike has suspension the increased speed you may develop also
increases your risk of injury. For example, when braking, the front of a suspended
bike dips. You could lose control and fall if you do not have experience with this
system. Learn to handle your suspension system safely. See also Section 4.C.
WARNING: Changing suspension adjustment can change the handling and
braking characteristics of your bike. Never change suspension adjustment
unless you are thoroughly familiar with the manufacturer’s instructions and
recommendations, and always check for changes in the handling and braking
characteristics of the bike after a suspension adjustment by taking a careful test
ride in a hazard-free area.
Suspension can increase control and comfort by allowing the wheels to better follow
the terrain. This enhanced capability may allow you to ride faster; but you must not
confuse the enhanced capabilities of the bike with your own capabilities as a rider.
Increasing your skill will take time and practice. Proceed carefully until you have
learned to handle the full capabilities of your bike.
WARNING: Not all bicycles can be safely retrotted with some types of
suspension systems. Before retrotting a bicycle with any suspension, check
with the manufacturer to make sure what you want to do is compatible with the
design. Failing to do so can result in catastrophic frame failure.
G. Tyres and Tubes
G1. Tyres
Bicycle tyres are available in many designs and specications, ranging from general-
purpose designs to tyres designed to perform best under specic weather or
terrain conditions. Once you’ve gained experience with your new bike, if you feel a
dierent tyre might better suit your needs, your stockist can help you select the most
appropriate design.
The size, pressure rating and, on some high-performance tyres, the specic
recommended use are marked on the sidewall of the tyre. The part of this information
which is most important to you is tyre pressure. Most Frog Bikes bicycle tyres are
covered by pressure rating ranges based on tyre size; however, certain tyres have
dierent pressure ranges based on the intended use of the tyre. To determine the
correct tyre pressure range for a specic tyre, please refer to the tyre pressure range
specied on the sidewall of the tyre, or refer to www.Frog Bikes.com for a list of tyre
pressures by tyre model.
