TYRE CARE AND WHEEL ADJUSTMENTS

To obtain maximum life and full benefit from your tyres, it is essential to maintain the recommended pressure indicated on

the tyre sidewall. Unnecessary hard braking and skidding greatly reduces tyre life. Make sure your tyres do not come into

contact with oil, petrol, paraffin or other rubber solvents. Make sure that your wheels run true and are in correct alignment

to avoid chafing the tyre sidewall against the bicycle frame or fork tubes. Tyres should regularly be inspected for wear and

cuts. Check that the tyre tread pattern is clearly showing all around the outside edge of the tyre. Check there are not any

breaks, cuts or uneven wear in the tyre. Tyres should be replaced if damaged. Tyre punctures can be caused by careless

riding over sharp stones, holes in the road, or by hitting curbstones. If you are storing your bicycle for a long period of

time, it is advisable to store the machine with the tyres off the ground to prevent them from becoming distorted. To inflate

tyres, a foot pump or normal bicycle inflator fitted with a suitable valve connector should be used along with an accurate

tyre pressure gauge. Wheels should be checked regularly for spoke tension. Perform this check more frequently if the

bicycle is used on rough roads.

Front wheels

Caution:

Your front wheel comes with a retention device to keep the wheel axle from

disengaging from the fork-ends if the wheel nuts or the quick-release are

incorrectly assembled. These devices are of two types.

1: Small protrusions machined or formed on the outer face of the fork-ends.

2: Shaped washers that contain a small tab/prong that engages in a hole

within the fork-end.

FRONT WHEEL REMOVAL AND REPLACEMENT

Disengage the brake quick release lever if your bicycle is so equipped.

Loosen both axle nuts by turning in a counter clockwise direction. Remove

axle nuts, washers, and axle retention device if fitted. Remove the front

wheel. The axle cone bearing adjustment should permit smooth rotation of

wheel with the cone locknut securely fastened against axle cone to prevent

loosening.

Replace the front wheel between the fork blades ensuring that the projecting

tab/prong of the retention device are securely fitted into the slot in the fork

ends or with standard washers securely in position butting against the

protrusions on the fork end. Securely tighten all wheel nuts ensuring that the

wheel is central within the forks. Refer to page 8 for recommended torque

settings.

Note. Reset brake quick release mechanism and check brake for proper

operation.

To Remove Rear Wheel

Move the chain onto the smallest rear sprocket. Disengage the brake quick release lever if your bicycle is so equipped.

Loosen both axle nuts by turning in a counter clockwise direction. Pull the derailleur mechanism gear rearwards for

additional clearance. Remove the rear wheel by sliding forward or down and out of the frame.

To install wheel, locate the top section of the chain on the small sprocket and replace the wheel into the frame by pushing

back and centralising between the chainstays. While holding the wheel in this position, tighten the axle nuts in a clockwise

direction securely ensuring that the wheel is central within the chainstays. Refer to page 8 for recommended torque

settings.

The wheel should turn freely and have no side play.

Reset rear brake quick release mechanism and check brake for proper operation.

ADJUSTMENTS

QUICK RELEASE FRONT WHEEL

To remove the front wheel, first release the front wheel brake. Then open the quick release lever on the axle and pull

the wheel from the forks.

To install, fit wheel into forks with quick release lever on the left side. Close quick-release, and tighten adjuster until

snug. Release quick-release lever and further tighten adjuster approximately 3/4 of a turn. Lock and check that

the quick-release has embossed the fork ends. It may be necessary to tighten or loosen the adjuster slightly.

Note. Reset brake quick release mechanism and check brake for proper operation.

Wheel must be clear frame and fork by at least 1-5mm.

The wheel should turn freely and have very little side-play.

Check quick release lever is in the correct and fully locked position before each ride.
