Before every ride
5.1.
Checking the tyres
The following applies to the tire pressure:
•
You can find the air pressure recommended by the manufacturer on the tire.
•
The greater your weight, the higher the air pressure you should choose.
•
The rear tyre should be driven with slightly more pressure than the front tyre
(0.2-0.5 bar), as about 60% of the weight is applied to the rear wheel.
In order to take full advantage of the main feature of the balloon tyre, i.e. its
excellent suspension properties, it should be ridden with low air pressure.
Keep trying until you reach the right tyre pressure for you.
Recommendation: 1.5-2.0 bar for 75 kg body weight.
We recommend that you check the pressure every 2 to 4 weeks, as bike
tubes continuously and inevitably lose air.
If the tyre pressure is too low, the risk of snakebite punctures increases.
The result of a snakebite puncture is a flat tyre.
A tyre damaged by cracks or foreign objects may lose its pressure. There is
a risk of accident!
-> Check for cracks or foreign objects in the tyre.
5.2.
Checking the brake system
•
Perform a brake test when at a standstill before every ride. To do so, pull each
brake lever towards the handlebar with normal braking force. The brake lever
must not touch the handlebar grip.
•
Move the vehicle back and forth with the brake applied. There must be no
significant play. If there is, get to the rootcause: The calliper or brake disc may
not be tightened. Tighten them to the torque values in the torque table in
section 9.3.
•
For hydraulic disc brakes, the pressure point on the brake lever must be stable.
If the pressure point is not reached after two-thirds of the lever stroke, pull
the lever several times in succession ("pumping"). Check if the pressure point
stiffens. In this case and if the location of the pressure point moves while
riding, the brake system must be bled by HNF-NICOLAI Service or by a qualified
specialist workshop.
