Servicing the Whyte Modular Dropout Systems:

6.1:

USING THE 12mm WHYTE QR SHAFT.

Referencing Figure 19 and 20. The rear wheel is attached to the frame by a lever

actuated mechanism that allows you to install

and remove the wheel without tools.

To undo and remove the axle from the bicycle, turn the lever anti

clockwise until the axle is disengaged from the threads in the

RH dropout, then pull the axle out of the hub and through the LH dropout to remove it from the frame. Note. If you have
placed the bike in a work

stand take care to support the rear wheel as you remove the axle, to prevent the rear wheel falling

out of the frame and potentially damaging any components in the process. If you are in the habit of turning your bicycle upside

down to remove the wheels, please take care not to damage the saddle or any of the controls on the handlebars when doing

so.

To re

assemble the axle, ensure the wheel is placed correctly into the frame and the hub is aligned with the dropouts. Insert

the Axle into the LH dropout and push it through the dropout, hub and into the RH dropout. Turn the lever clockwise.
After inserting the axle through the dropout of the frame and wheel hub, it will be necessary to turn the lever several
times to fully engage the axle into the threads in the RH dropout before the axle tightens. The required minimum hand

force is 15 Nm.

WARNING: If you are unsure about how tight the axle needs to be done up to, DO NOT ride your bike and instead
consult your Whyte Dealer who will be able to advise and demonstrate the correct closing force.

Ensure that the lever is back to its normal position after every adjustment is made. To do this, pull the spring

loaded ever arm

away from the bike (Fig. 19 Arrow No.1) until the lever arm dis

engages from the axle (Figure 20) Whilst the lever is dis

engaged from the axle, rotate the lever (Fig.19 Arrow No.2) around to a

‘9’0’

clock

’

position as shown in Fig. 20. Next release

the spring

loaded Lever arm to re

engage the Lever Arm with the axle (Fig.19 Arrow No.3).

Under no circumstances should the 4mm Allen Screw in the centre of the Axle Lever arm be loosened. Do not loosen the screw
for opening or closing of the Axle System.

Always check for safety before riding

Before every ride check your thru axle System is in the Locked (CLOSED) position. Make sure that the wheels are cor-

rectly installed on the bicycle frame or fork, and the lever does not contact any part of the bicycle. If the lever contacts

anything, it might not be closed; replace the thru axle or consult your dealer for safety. Ensure that the tightening force

of the thru axle lever is minimum 15 Nm.

WARNING:

A thru axle that is not correctly adjusted and closed to a minimum hand force of 15Nm, may allow the wheel to

work or become loose or become detached from the bike unexpectedly. This could cause the rider to lose control and fall and

may result in serious injury or death. Always make sure the thru axle is adjusted and closed correctly before every ride as part

of your Pre

ride checks.
