If your front fork has an integral secondary 

retention device, loosen the tension adjusting 

nut enough to allow removing the wheel; then 

go to the next step. Raise the front wheel a few 

inches off the ground and tap the top of the 

wheel with the palm of your hand to release 

the wheel from the front fork.

4.B.2.B. Installing A quick release front 

wheel

4.B.2.B.1. 

Move the quick-release lever so 

that it curves away from the wheel. This is the 

OPEN position.

4.B.2.B.2.

 With the steering fork facing 

forward, insert the wheel between the fork 

blades so that the axle seats firmly at the top 

of the slots which are at the tips of the fork 

blades – the fork dropouts. The quick-release 

lever should be on the left side of the bicycle. If 

your bike has a clip-on type secondary

retention device, engage it.

4.B.2.B.3. 

Holding the quick release lever in 

the OPEN position with your right hand, tighten 

the tension adjusting nut with your left hand 

until it is finger tight against the fork dropout.

4.B.2.B.4. 

While pushing the wheel firmly to 

the top of the slots in the fork dropouts, and 

at the same time centring the wheel rim in the 

fork, move the quick release lever upwards 

and swing it into the CLOSED position. The 

lever should now be parallel to the fork blade 

and curved toward the wheel. To apply enough 

clamping force, you should have to wrap your 

fingers around the fork blade for leverage, and 

the lever should leave a clear imprint in the 

palm of your hand.

Warning: Securely clamping the 

wheel takes considerable force. If 

you can fully close the quick release 

without wrapping your fingers around 

the fork blade for leverage, and the 

lever does not leave a clear imprint 

in the palm of your hand, the tension 

is insufficient. Open the lever; turn 

the tension adjusting nut clockwise a 

quarter turn; then try again.

4.B.2.B.5. 

If the lever cannot be pushed all 

the way to a position parallel to the fork blade, 

return the lever to the OPEN position. Then 

turn the tension adjusting nut anti-clockwise 

one-quarter turn and try tightening the lever 

again.

4.B.2.B.6.

 Re-engage the brake quick release 

mechanism to restore correct brake pad-to-rim 

clearance; spin the wheel to make sure that 

it is centred in the frame and clears the brake 

pads; then squeeze the brake lever and make 

sure that the brakes are operating correctly.

4.B.2.C. Removing a quick release rear 

wheel

4.B.2.C.1.

 Shift the rear derailleur to high gear 

(the smallest, outermost rear sprocket).

4.B.2.C.2.

 If your bike has rim brakes, 

disengage the brake’s quick release 

mechanism to increase the clearance between 

the wheel rim and the brake pads.

4.B.2.C.3. 

Pull the derailleur body back with 

your right hand.

4.B.2.C.4. 

Move the quick release lever to the 

OPEN position.

4.B.2.C.5.

 Lift the rear wheel off the ground a 

few inches and, with the derailleur still pulled 

back, push the wheel forward and down until it 

comes out of the rear dropouts.

4.B.2.D. Installing a quick release rear 

wheel

4.B.2.D.1. 

Make sure that the rear derailleur is 

still in its outermost, high gear, position.

4.B.2.D.2. 

Pull the derailleur body back 

with your right hand, turn off the clutch if the 

derailleur has this feature, engage the clutch 

again once wheel is installed.

4.B.2.D.3. 

Move the quick release lever to the 

OPEN position. The lever should be on the 

side of the wheel opposite the derailleur and 

freewheel sprockets.

4.B.2.D.4. 

Put the chain on top of the smallest 

freewheel sprocket. Then, insert the wheel up 

and back into the frame dropouts and pull it all 

the way into the dropouts.

4.B.2.D.5. 

Tighten the quick release adjusting 

nut until it is finger tight against the frame 

dropout; then swing the lever toward the front 

of the bike until it is parallel to the frame’s 

chainstay or seatstay and is curved toward 

the wheel. To apply enough clamping force, 

you should have to wrap your fingers around a 

frame tube for leverage, and the lever should 

leave a clear imprint in the palm of your hand.

Warning: Securely clamping 

thewheel takes considerable force. 

If you can fully close the quick 

release without wrapping your fingers 

around the seatstay or chainstay 

for leverage, and the lever does not 

leave a clear imprint in the palm of 

your hand, the tension is insufficient. 

Open the lever; turn the tension 

adjusting nut clockwise a quarter 

turn; then try again. The rear wheel 

must be secured to the bicycle frame 

with sufficient force so that it cannot 

be pulled forward by the chain, even 

under the greatest pedalling force. 

If the wheel moves under pedalling 

force, the tyre can touch the frame, 

which can cause you to lose control 

and fall.

4.B.2.D.6. 

If the lever cannot be pushed all 

the way to a position parallel to the chainstay 

or seatstay tube, return the lever to the OPEN 

position. Then turn the adjusting nut anti-

clockwise one-quarter turn and try tightening 

again.

4.B.2.D.7. 

Push the rear derailleur back into 

position.

4.B.2.D.8. 

Re-engage the brake quick release 

mechanism to restore correct brake pad-to-rim 

clearance; spin the wheel to make sure that 

it is centred in the frame and clears the brake 

pads, then squeeze the brake lever and make 

sure that the brakes are operating correctly.

4.B.2.E. Installing wheels with through 

axles

Nukeproof bikes typically will use through 

axles, typically a 6mm Allen Key for the front 

and 5mm Allen Key for the rear axles.

1.  Insert the wheels to the fork and 

frame dropouts, ensure the rotor 

is aligned with the caliper to avoid 

damage when installing. For the rear 

wheel please ensure the gears are 

in the smallest sprocket and pull the 

derailleur rearwards to give more room 

for install. Ensure the hub endcaps are 

seated correctly in the dropouts for a 

secure fit. 

2.  Apply a little grease to the axle and 

threads and push through the dropouts 

and hubs until axle cannot be pushed 

further. 

3.  Tighten the through axle clockwise to 

the Nm found on the axle, if no Nm is 

displayed, please consult with your 

Authorised Nukeproof Dealer.

4.  If the through axle is stiff when 

installing, it may be cross-threading, 

stop immediately and check seating 

of hubs and dropouts. Any further 

concerns please consult with your 

Authorised Nukeproof Dealer. 

5.  If the forks have pinch bolt dropouts, 

reference the forks manufacturer 

guides for correct installation. 

6.  If the through axles have quick release 

levers, please reference the axles 

manufacturer’s instructions for correct 

install. 

7.  Ensure the correct tools are used 

when fitting and removing through 

axles, if you are unsure, please consult 

with your Authorised Nukeproof 

Dealer. 

8.  Ensure the through axles are checked 

before and after each ride to ensure 

they are tight. 

9.  Riding with loose through axles can 

result in loss of control, injury, and 

death.  

If you are unsure on fitting wheels with through 

axles, please consult with your Authorised 

Nukeproof Dealer.
