7.3 Wheel Fastening with Quick-Releases.
The wheels are attached to the frame at the hub axles. Each axle is
clamped tight in the drop-outs (a) by means of a quick-release.
Quick-releases require no tools at all. Just release the lever (b), unscrew
it a few turns, if necessary, and take out the wheel (see chapter “How to
Use Quick-Releases and Thru Axles“).
However, a thief will nd this just as easy to do! As an anti-theft measure
you can replace the quick-releases by special locks. They can only be
opened and closed with a special, coded key or an Allen key (c).
Never ride a bicycle without having rst checked whether the
wheels are securely fastened! A wheel that comes loose whilst
riding will throw you off your bicycle!
If your bicycle is equipped with quick-releases, be sure to lock
the frame to an immovable object together with the wheels
when you leave it outside.
7.4 Wheel Fastening with Thru Axle
Systems.
There is a wide range of different thru axle systems (d) currently avail-
able. Some systems are tightened with quick-releases. Other systems
may require special tools for assembly or disassembly.
Check the fastening after one to two hours in use and then every 20
hours of use.
For more information read chapter “How to Use Quick-Re-
leases and Thru Axles”.
Always observe the enclosed instructions of the fork manufac-
turer.
