DETAILED MAINTENANCE

When re-fitting the stem, make sure the handlebars are correctly aligned and tightened using the 

appropriate hex wrench or Allen key to a minimum 17Nm of torque. Do not over tighten.

test the security of the handlebars stem within the fork steerer tube, by clamping the front wheel 

between your knees and trying to move the handlebars up and down and from side to side. The 
handlebar should not move when applying turning pressure.

“a Headset” type assemblies

this type of head set differs from standard types by utilising an unthreaded, full-thickness bicycle 

fork steering tube. The mechanism is adjusted via on Allen headed compressing bolt, then fastened 

by clamping the handebar stem directly onto the fork steerer.

Fastening An AHead Stem To The Fork 

In assembling a new bike with this type of fitting, remove dust cap covering the Allen head bolt and 

unscrew bolt and unscrew bolt holding the top plug. Make sure handlebars and forks are facing the 

front. Tighten down the steering assembly via the Allen head centre bolt so there is no freeplay. 
Do not overtighten. Tighten up the binder bolts which clamp the handlebar stem to the fork 

steerer. the handlebar and stem must not be able to turn on the steerer tube.

If adjustment is later required: loosen the stem binder bolts, re-seat the compression mechanism 
via the Allen bolt, then securely re-tighten the stem binder bolts.

test the security of the handlebars stem within the fork steerer tube, by clamping the front wheel 

between your knees and trying to move the handlebars up and down and from side to side. The 
handlebar should not move when applying turning pressure.
