1.5.2 Thru Axles.
Thru axles are mounted when the bicycle has to withstand high stress
occurring e.g. during freeriding, downhill riding etc. or jumps. They pro-
vide suspension forks with a suitable stiffness.
Before mounting or replacing a fork/wheel combination, be
sure to read the operating instructions of the respective sus-
pension fork or wheel manufacturer rst.
Notes on How to Mount Thru Axle Wheels.
There is a wide range of thru axle systems available now. Some systems
are tightened with quick-releases. Other systems may require special
tools for assembly or disassembly (a+b).
Be sure to read the respective manual before doing any as-
sembly work.
If you are in doubt or if you have any questions, please contact a bicycle
specialist shop of your trust!
Improperly mounted wheels may throw you off your bicycle or
result in serious accidents!
Check the fastening after one to two hours in use and then every 20
hours of use.
For the removal of the front wheel you may need tools (c) depending on
fork manufacturer and thru axle system. To remove the wheel, loosen
the axle support at the fork and remove the axle completely from the
hub.
To remount the front wheel proceed in the reverse order. Make sure all
bolts/quick-release systems are tightened properly.
To mount the axle use only the tools recommended by the
manufacturer. Make it a rule to use a torque wrench (d). Tighten
carefully by approaching the prescribed maximum torque in
small steps (0.5 Nm increments) whilst constantly checking the
proper t of the component. Never exceed the maximum tight-
ening torque indicated by the manufacturer! A too tight xing of
the axle can damage the axle or the fork leg.
Check the bolts after one to two hours of use and then every 20
hours.
