Maintenance Instructions

Axle Nut

Important – Please read these instructions fully

NOTE: It is recommended that your bicycle has a regular maintenance check every six months

carried out by a competent cycle mechanic to ensure that it is operating in perfect running order.

Frequent inspections should be carried out to ensure that all nuts, bolts and hardware are

secure and that no parts are worn or damaged.

Bearing Adjustment:The cones of all bearings should be periodically checked to ensure they

are smooth and free from excessive play. If excessive side play occurs at the wheel rim, loosen

the axle nuts, loosen the cone lock nut “A” and adjust cone “B” with the multi-sized spanner.

Tighten lock nut “A” and tighten the axle nut.

Brake: Ensure that the brakes operate smoothly without locking or grabbing when applied. Make

periodic checks for wear and tear. Worn brake blocks and damaged brake cables MUST be

replaced immediately. For the best results use genuine replacement parts.

If on inspecting the brake blocks there is less than 3mm (1/8”) of rubber protruding from the

metal brake block holder then the brake block must be replaced.

Calliper Brake: Brake callipers should function freely and release fully. If callipers bind we

recommend the following sequence of checks:

1. Make sure the brake lever and lever pivot operate smoothly. They should be clean and

lightly lubricated.

2. The inner brake cable must move freely within the outer brake cable. Inner brake cables

must be oiled or greased periodically.

3. Brake callipers should function freely. If the callipers are tight, adjustment of the brake

centre pivot bolt may be required. Using 2 suitable 10mm spanners, hold the inner pivot nut

inner pivot nut anticlockwise (loosen) until the callipers do not bind BUT ARE NOT LOOSE.

Hold the inner nut (C) in this position and tighten the outer nut (D) so that both nuts are

locked together.

If the brake lever travel becomes excessive, loosen nut (A) and unscrew adjuster (B). This will

bring the brake blocks closer to the wheel rim. When adjusted, lock nut (A) against the brake

arm.

Maintenance Instructions

Important – Please read these instructions fully

NOTE: Should one brake block (F) make contact with the wheel rim before the other, the brake

can be centralised. Using a hammer and a suitable punch, tap the return spring (E) on the

opposite side to the calliper/brake block that touches the rim first.

V Type Brakes

WARNING: V type brakes are powerful and sensitive. Until you are completely familiar with their

performance, use them with caution. Improper use may result in loss of control.

Maintenance Instructions

Important – Please read these instructions fully

This type of brake offers powerful all round braking performance. They are not difficult to set up

and it is relatively easy to release the brake cable tension in order to remove or install a wheel

without deflating the tyre. To carry out this task, squeeze both brake arms together until the

brake blocks are firmly in contact with the wheel rim. This can be accomplished with the thumb

and fore finger/index finger of one hand. Hold the guide pipe in the other hand and carefully pull it

until the conical end disengages from the pivoted cage. Raise the guide pipe and cable until the

brake inner cable clears the cage. Release both brake arms. To connect the brake, reverse this

procedure.

The height and angle of each brake block can be adjusted by loosening the brake block holder

nut with a 10mm spanner. To obtain good braking performance, the length of the inner brake

cable between the pivoted cage and brake arm i.e. the part of the cable covered by the rubber

boot, should be approximately 40mm. Carefully loosen one brake block and hold it against the

wheel rim. Using a 5mm hexagonal / Allen key inserted in the front of the brake block holder to

maintain this position, securely tighten the 10mm retaining nut at the rear of the brake.

Repeat this procedure with the opposite brake block making sure that each brake block is the

same distance from the holder, each block is the same height and each block is parallel to the

wheel rim.

On squeezing the brake lever, both brake arms should operate simultaneously and the brake

blocks should make good contact with the wheel rim. The clearance between each brake block

and rim should be between �mm-�mm. When viewed from the front, the left hand brake arm and

brake block assembly should be a mirror image of the right hand side.

Either one or both arms may be fitted with a small adjusting screw near their pivoted end. This

screw adjusts the return spring tension and by turning it clockwise (more tension) or

anticlockwise (less tension) it should be possible to balance each brake arm so they operate

together.

IMPORTANT: For your own safety, make sure both brakes work efficiently before each ride.

Check the security of all nuts, bolts and fixings and replace worn or damaged brake blocks and

cables.

Chain: The chain should have approximately 10mm (3/8”) of vertical movement when checked

in the centre between the front and rear sprockets. To adjust the chain tension, slightly loosen

the rear axle nuts and either pull the rear wheel backwards if the chain is too loose, or push it

forwards if the chain is too tight. Before securely re-tightening the rear axle nuts make sure that

the chain is correctly tensioned and the rear wheel runs centrally. Oil your chain sparingly once a

month by revolving the pedal cranks and apply to each link. Wipe away excess oil with a dry

cloth.

Bottom Bracket Adjustment (1 piece)

A correctly adjusted one piece crank should rotate freely and have no side play. To check for

play, hold both the left and right crank arms and try to move them in a rocking motion (pull/push).

If excessive play is felt then the crank must be adjusted.

Slot

Lock Nut

Crank Arm

Adjustable Cone

Lock Washer

Tools: The tools required to adjust a one piece crank are: an adjustable spanner with a jaw width

of up to 32mm, a small hammer/mallet and an old flat headed screwdriver.

Adjustment:

Note – the lock nut and adjustable cone BOTH have a left hand thread i.e. They undo in a

clockwise direction.

Using the adjustable spanner, loosen the lock nut and rotate this by 1 or 2 turns. Prise the slotted

lock washer away from the adjustable cone to ensure good access to the adjustment slots.

Locate the head of the screwdriver into the slot and carefully tap the end with a mallet/hammer to

rotate the cone.

Excessive play? Cone must be tightened. Turn anti-clockwise.

Cranks too tight? Cone must be loosened. Turn clockwise.

Whilst carrying out this adjustment, frequently check the bearings for play/free rotation and when

correct, move the lock washer against the cone and tighten the lock nut. Turn anti-clockwise.

Ensure the lock nut is firmly secured. If you have any doubt about the adjustment of the bottom

bracket bearings, ask a competent cycle mechanic to make the adjustment.

Cleaning: Your bicycle should be cleaned with warm soapy water (except the chain). Rinse with

clean water and dry with a soft clean cloth, afterwards oil the bicycle in the appropriate areas.

On paintwork use a good wax polish.

Handlebars: Adjust for comfort and a proper fit. Make sure that the handlebar stem is inserted to

at least its Minimum Insertion mark. Securely fasten the handlebar bolt and nut/expander bolt.

Replace any worn grips.

Lubrication: To ensure that the bicycle remains in good working order, moving parts should be

lubricated regularly.

Maintenance Instructions

Important – Please read these instructions fully

The front hub, rear hub and headset are greased prior to leaving the factory. Correct further

lubrication requires disassembly, cleaning and re-packing and should be done by a qualified

bicycle mechanic.

Using a light machine type oil periodically lubricate the chain, rear wheel sprocket, brake lever

pivots, brake inner cables and the calliper brake centre bolt or V brake pivot points (depending

on the type of brakes fitted).

To avoid over lubricating, do not oil where lubricant is still evident from the previous maintenance.

Should you accidentally over lubricate, wipe clean any excess.

WARNING: Should any oil come into contact with the wheel rim or brake blocks, this should be

wiped off and the components cleaned with a de-greasing agent.

NOTE: When storing your bicycle for prolonged periods, smear any chrome plating with light

grease.

Punctures: Inner tube punctures can be caused by riding over sharp stones, holes in the road or

by hitting curb stones.

In the event of a puncture the tyre should be completely removed. With the inner tube deflated,

push the tyre to the centre of the rim. Carefully hook a tyre lever (not supplied with the bicycle)

under the edge of the tyre and gently lever the tyre bead over the edge of the rim. Repeat this

procedure with a second tyre lever positioned a few inches away from the first one. It should now

be possible to pull the complete side of the tyre off. Push the valve back through the rim and

remove the inner tube. Finally, remove the tyre.

Carefully check the inside of the tyre for sharp objects that may have caused the puncture i.e.

nails/ pins/ thorns etc. These must be removed.

Repair the inner tube using a puncture repair kit – follow the instructions supplied.

To replace the tyre, fit one side of the tyre back onto the rim. Push the valve through the rim

valve hole and feed the inner tube into the tyre. Make sure the inner tube is slightly inflated and

then ‘work’ the tyre back on to the rim using both thumbs.

Slowly inflate the tyre making sure it is sitting squarely and is sealed correctly on the rim. When

fully inflated replace the valve cap.

Saddle: Adjust for comfort and proper fit. Never allow the ‘minimum insertion’ mark to show

above the top of the seat tube.

Steering: The steering of your bicycle should be smooth and easy.

Tyres: To obtain the maximum life and full benefit from pneumatic tyres, ensure they are inflated

according to the pressure indicated on the tyre sidewall. Your tyres should be inflated

slowly, using a manual foot or hand pump fitted with a “Schrader” valve connector and pressure

gauge.

Pressurised pumps should not be used.

Ensure the tyre is properly positioned onto the wheel rim as incorrect alignment can cause

chafing of the tyre against the frame or fork tubes. Make sure that when purchasing replacement

tyres you obtain the correct size. The tyre size is found on the tyre sidewall.
