riese und müller GmbH Frog Manual
inflated to the correct pressure. Puncture resistance is also improved when running at the correct pressure. In particular, rupturing
of the inner tube when going over a sharp edge (so-called ‘snake-bike’ punctures) are caused by too little pressure.
The pressure recommended by the manufacturer is marked on the side of the tyre. The following table shows pressure in Bar:
PSIBAR
40 2.8
503.5
60 4.1
70 4.8
Danger: Never pump your tyres up above the maximum recommended pressure! The tyre could blow away from the rim as you
ride, or explode. Accident danger!
The tyres and rim alone are not airtight. To retain the internal pressure the inner tube is placed inside the tyre. It is filled through
a “Schrader” valve (like automobile tyres) and can be refilled at every gas station.
If the valve body of the Presta valve isn’t properly screwed down, this can lead to air loss. Check the location of the valve body in
the valve shaft.
Hand-pumps are often not suitable for achieving high pressure. Track pumps with a gauge are better, as you can check the
pressure as you pump.
Danger: Always ride with the recommended tyre pressure, and check it at regular intervals.

Check that the valve is an appropriate diameter for the hole in the rim, and that it always stands up straight!
Tyres with the tread worn away, or with damaged side-walls, should be replaced. The interior of the tyre can be damaged should
moisture or dirt get in. Defective rim tape should be replaced immediately.
Damage to tyres can in extreme cases lead to sudden blow-outs, which could cause serious accidents!
Rim truing, spoke tension.
The spokes keep the hub in the centre of the rim. Even spoke tension is necessary for the true running of the wheel. If the tension
of one spoke changes, for example after hitting a step at speed, or because of spoke breakage, the tension forces go out of
balance and the rim will no longer run true.
Even before you notice this imbalance through wobbling, the functioning of your bike will already be impaired.
The side-walls of the rims are usually contacted by the brake blocks simultaneously. If the wheel is no longer running true, braking
performance can be affected.
Check the roundness of your wheels from time to time. Lift the wheel off the ground and give it a spin by hand. Watch the gap
between brake blocks and rim. If this gap varies by more than a millimetre, the wheel should be re-trued by an expert.
Hint: Truing wheels is a difficult business, which should definitely be left to your dealer!
PAGE 28, Securing wheels with axle nuts, Fixing a puncture
Wheels are fixed to the frame via the hub axles. The axle will be fitted with six-sided axle nuts to secure it in the ‘drop-outs’.
Danger: Never ride a bike if you haven’t first checked that the wheels are secure. If a wheel comes loose as you are riding, you’ll
have a nasty crash!
The axle nuts on the Frog should be tightened or loosed with a 15mm spanner. This tool should be carried with you on rides,
because without it punctures can only be repaired with considerable difficulty.
Fixing a puncture
A puncture is a pain for any rider. But the dreaded hiss need not mean the end of a day’s cycling, so long as you carry with you
the tools needed to replace tyre and inner tube, and a spare tube or puncture-kit.
Wheel removal
· With V-brakes, you must first unhook the cable. To do this, put one hand around the tyre and pull the brake pads or brake
arms together. When this is done the cable can be unhooked easily.
· Now the air has to be released from the tyre. Just turn off the cap of the valve and press with the cap onto the valve.
· On the Frog with coaster brake, you must also undo the reaction arm, which transmits drive and braking loads to the frame.
