About this instruction manual

This instruction manual provides you with the information you need to maintain and use your Koga bicycle safely. The manual describes only the major parts of the bicycle and the most common settings. This manual is intended for all types of bicycles from Koga. That means that certain information might not apply to your Koga bicycle. Visit www.koga.com to find the most up to date version of this document.

Manuals for specific parts may have been supplied along with your Koga bicycle. Consult these manuals if you want extra information about the part in question. If you want more information about a certain part, or you want to make adjustments that have not been described in these manuals, contact your Koga dealer.

Safety

Use the bicycle for the purpose for which it was designed.

Traffic

Every rider is legally obliged to maintain his or her bicycle in a condition that is safe for traffic and ready for riding. Make sure you are familiar with these legal obligations so you are not faced with unwelcome situations.

Koga supplies bicycles that meet the legal obligations for the purpose for which they are made. The Trekking, Comfort, Special and most of the Light Touring bicycles are suitable for public roads. The Race, MTB and a few Light Touring bicycles are not suitable for public roads if they do not have the necessary adjustments. In their standard models they do not have any lighting, and therefore may not be ridden on public roads in conditions of poor visibility. Separate light units are available for these bicycles.

Ride particularly carefully on wet road surfaces. The braking distance is longer on a slippery road surface.

Use lights that work properly in all cases of poor visibility.

(Cycle) clothing

When riding your bicycle, wear close-fitting pants, or use a bicycle clip. Loose clothing can get between moving parts.

Koga is not liable for grease and/or lubricants in clothing.

When riding your bicycle, wear clothing that attracts attention. When riding your bicycle, wear a DIN-EN 1078 approved bicycle helmet.

Before you start riding, check that:

• The wheels are properly mounted.
• The brakes work properly.
- The saddle is at the correct height.
- The seat post is at the correct height.

• The seat post is at the correct height.
• The lights work properly.
• The gears work properly.
  • The bolts, nuts and pedals are attached firmly.
• The air pressure in the tyres is correct.
• The tread of the tyres is correct.

After an accident

After an accident or a fall, have your Koga dealer check your Koga bicycle thoroughly.

• A bent or deformed aluminium frame cannot be repaired.
• A slightly bent or deformed steel frame can be repaired.
• After an accident, carbon parts must be replaced entirely. Carbon parts can receive visible and invisible damage.

Accessories and equipment

You can mount extra accessories on your Koga bicycle. All parts that are mounted additionally on the bicycle must be suitable for the Koga bicycle. Therefore, use accessories only in consultation with your Koga dealer. Parts that do not fit can lead to damage or accidents.

KOGA

Handlebar bags and baskets

When you use handlebar bags or baskets, check that:

• the lights are not obstructed.
• cables are not jammed.
- the handlebar and the frame are not damaged.
• steering is not influenced.

Never carry more than 5 kg in handlebar bags or baskets.

Aluminium handlebars are not directly suitable for handlebar bags or baskets. Special attachment brackets are available for aluminium handlebars.

Child seats and trailers

Always consult your Koga dealer about the type of child seat or trailer that is suitable for your Koga bicycle. Always take your Koga bicycle along with you to your Koga dealer

• Buy only EN 14344 approved child seats.
- Riding with children has a significant effect on the cycling behaviour of the bicycle. The braking distance is always longer.
• Make sure no limbs can come between moving parts.
• Make sure fingers cannot come between suspension parts of the saddle.
- Never transport more weight on the luggage carrier than specified. It can result in the luggage carrier breaking and serious accidents.
• Children must always wear a helmet and a seat belt.
- Never leave children behind on a parked bicycle. First take the child from the bicycle and then put the bicycle on its stand.
- Never use more than one child seat on the bicycle.
- The Light Touring men's bicycles are not suitable for child seats
- Aluminium handlebars are not suitable for child seats.

• Children up to a maximum of 20 kg may be carried in child seats.
• Only cyclists at least 16 years of age may carry children.

Bicycle carriers

A number of types of bicycle carriers (on car, caravan, camper etc.) can damage your bicycle when mounting or transporting it. An incorrect mounting position or tightening the mounting construction too far can cause damage to the frame/front fork. The damage to the frame or fork can result it in it breaking.

Environment

Dispose of excess lubricants, cleaning agents and paints. Dispose of these agents as specified on their packaging and take local legislation into consideration. If you are discarding a bicycle, return it to your Koga dealer or dispose of it in accordance with local authority's.

Proof of ownership

Have your Koga dealer fill in the proof of ownership completely, and place his signature and business stamp.

Check that frame number, lock number, key number and chip number have been filled in. Store the proof of ownership carefully. It is also the guarantee.

The proof of ownership is unique and can therefore only be issued once.

Guarantee

You are entitled to 2 years guarantee on your Koga bicycle (Details page 22). You are also entitled to a lifetime guarantee for the frame against manufacturing faults. The guarantee period starts on the day of sale by the dealer. The guarantee is solely for the first owner of the Koga bicycle. The guarantee can never be transferred. Damage due to overdue maintenance is not covered by the guarantee. The full guarantee provisions can be found at the back of this instruction manual.

Frame

The frame can end up bent after an accident or a fall. If you are uncertain, have your Koga dealer check the frame. In some cases the frame can be straightened.

Never ride bicycle with a frame that has cracks or is visibly bent. Take your bicycle to a Koga dealer.

Maintenance

Treat paint damage and rust spots immediately with original Koga paint pens (1A). Keep the frame clean. Regularly polish the frame with car wax or cleaning oil.

Always remove oil and grease residue from the paint.

After cycling on roads with salt on them, fully rinse your bicycle with cold water. Never use warm water because this encourages the corrosive working.

Perspiration

Perspiration is highly conducive to corrosion.

Clean and treat the places that are exposed to perspiration extra.

Corrosion caused by perspiration is not covered by the guarantee.

Maintenance of polished (frame) surface

Polished surfaces are provided with a durable blank lacquer layer. Stone chippings or user damage can cause damage to the blank lacquer, which can lead to corrosion in the long term. It is therefore of great importance that you regularly check your frame for (blank) lacquer damage and touch it up where necessary. It is important to apply sufficient lacquer; generously on the place of the damage so that it is fully closed off from exposure to the weather.

A blank lacquer paint pen is available from your Koga dealer.

Frame number

The frame number can be found on the frame sticker (2A).

Di2 electronic shifting system

Road racing bicycles featuring the Shimano Di2 electronic shifting system with an internal battery have been developed with a carrier at the water bottle basements at the inside of the seat tube. The battery is mounted into this carrier. This battery carrier is positioned and mounted with an M5 stud. Charging the battery is carried out through the control unit located at the stem.

Chain and toothed belt drive

Chain

Make sure your chain is sufficiently lubricated.

A poorly lubricated chain rusts extremely quickly and is subject to excessive wear.

Never use too much grease or lubricant. Dirt and dust adhere well to them.

Regularly check the play on the chain. The play on the top part of the chain may not exceed 2 cm (1A).

Replacing and tensioning chains requires special tools. Leave this job up to your Koga dealer.

Toothed belt drive

Maintenance

Clear off rough dirt regularly, particularly from the toothed side of the belt.

Do not lubricate the belt.

The working life and proper functioning of the belt can be affected by:

• twisting
• folding, kinking or rolling up
• Turning inside out
• Knotting
• Excessive dirt
• Objects coming between the teeth of the drive belt (pebbles, twigs etc.)

Replacement of the toothed belt drive

With normal use and regular cleaning, the toothed belt has a long working life. We recommend that if it is ever necessary, belt replacement is carried out only by a Selected Koga Dealer.

Maintenance, usage and guarantee conditions for Koga wheel sets

Maintenance

• Regularly disassemble the quick release, clean and grease the shaft (Also see Koga instruction booklet p. 10)
• Never clean the wheels with a pressure washer. Only use water with detergent. Do not use an abrasive sponge. Dry off the wheel after washing it or, or rain, in order to prevent oxidation.
• In order to retain optimal braking power, avoid traces of oil or grease etc. on the brake surface.
• Regularly clean the brake surface of your rims with grease-free products.
• Check the brake blocks for foreign particles (stones, bits of metal etc.) Also check the state of the brake blocks and replace them regularly.
• When the brake blocks make contact with a new rim, this may cause noise. This noise will disappear after a certain running in period.

Important Information for your safety during use

• Make no adjustments whatsoever to your wheel
- Check the correct functioning of the quick releases before every ride.
- Every wheel is only intended for the specifically indicated usage. For example: a race wheel for the road, MTB wheel for Cross Country circuit, etc.
- Check the degree of wear on the brake walls. Replace the rim if it is worn. (Also see Koga instruction booklet p. 11) Inspect the inside of the rim (underneath the rim ribbon) and the outside of the rim for traces of metal fatigue or wear: worn in brake walls, tears in the side walls or at the spoke nipple.
- Respect the prescribed spoke tension. A different spoke tension can create tension concentrations or can weaken it. Contact your recognised Koga dealer for this.
- Consult your Koga dealer for every defect of your product.

- Not respecting the recommendations is at the user's risk and will cancel the validity of Koga's guarantee.

Guarantee conditions for Koga bicycles

Article 1 Guarantee

1.1 Koga provides a guarantee only to the first owner of the bicycle in question; the second or following owner can only call in the party from whom the bicycle was purchased in the event of damage.

1.2 Guarantee lapses in accordance with the provisions of articles 3.1 and 5.1.

1.3 The guarantee cannot be transferred.

Article 2 Guarantee period

2.1 Every Koga bicycle has a limited life, the so-called useable life cycle. The duration of the useable life cycle of bicycles depends on the type of frame, the way in which and the circumstances under which the bicycle is ridden and the care/maintenance the bicycle receives. The duration of the useable life cycle is not equal to the duration of the lifetime guarantee period. The lifetime guarantee period is established on the basis of the duration of the useable life cycle of the bicycle. This cycle depends to a great extent on various factors; these factors are stated in article 2.5. Koga sets this cycle at an average of 25 years. Koga frames and non-suspension front forks have a lifetime guarantee on the absence of construction and/or material defects, this guarantee applying to all aluminium, Scandium and chrome-molybdenum frames and non-suspension front forks. The warranty period for carbon frames is 10 years. Spring frames have a warranty period of 3 years. Frames and forks that are or have been used in (professional or semi-professional) races have been excluded from the warranty. The above-mentioned warranty periods apply to the current product range. The warranty periods for our earlier products ranges are to be found on our website (www.koga.com) or through the dealer.

2.2 For front suspension forks, dampers and all other parts, except for the parts mentioned in paragraphs 1 and 4 of this article, there is a guarantee on the absence of construction and/or material defects for a period of 2 years.

2.3 For paintwork of frame and non-suspension front forks there is a guarantee period of 10 years for the absence of corrosion and oxidation from the inside, if the bicycle is well maintained. For other paintwork and chrome parts there is a guarantee period of 2 years for the absence of corrosion and oxidation from the inside, if the bicycle is well maintained.

2.4 No guarantee is given for parts subject to wear, such as tyres, chain, chain rings, back gear rings, cables and brake blocks, unless there is a question of construction and/or material defects.

2.5 Among other things, the following factors or a combination of these factors can influence the useable life cycle of a bicycle: use of the bicycle for competitions and intensive training, use of the bicycle for purposes for which it was not designed, excessive weight, riding in all weather conditions or different climates, geographical circumstances. Koga recommends all Koga bicycles be checked regularly by a recognized Koga dealer for signs of potential problems such as corrosion, break, deformation and improper use.

These preventative checks are important for preventing accidents and injuries. In principle, service checks are not free of charge.

Article 3 Guarantee exclusions

3.1 The guarantee lapses in the following cases:

a. Improper and/or careless use of the bicycle and use that does not correspond with its intended use;

b. The bicycle has not been maintained in accordance with the user manual;

c. Technical repairs have not been performed in a competent manner;

d. Parts mounted at a later date do not correspond with the technical specification of the bicycle in question or have been mounted incorrectly;

e. The bicycle is used for hire or made available to more than one unspecified person in other ways.

3.2 Furthermore, Koga B.V. expressly disclaims any responsibility for damage to (parts of) the bicycle as a result of:

a. Incorrect adjustment/tensioning of the handlebar, saddle, seat post, derailleur set, brakes, quick release of the derailleur set, brakes, quick release of the wheels and tyres; and mounting/transporting it on bicycle carrier. b. Not replacing parts in time such as brake or derailleur cables, brake blocks, tyres, chain and gear wheels;

4.2 Any expenses of mounting or disassembly are at the expense of the owner.

4.3 Contrary to the provisions of the previous paragraph, for frames and front forks the labour wages are at the expense of the manufacturer during 3 years after the date of purchase.
4.3.1 Costs of transport of the bicycle and/or parts from and to Koga B.V. are at the expense of the owner.
4.3.2 If a certain part qualifies for guarantee, this part will be replaced by a new part or equivalent part. Koga B.V. cannot, however, guarantee that frame types or colours remain available.
4.4 Parts that no longer fit technically, or are no longer available for the replacement guarantee frame are delivered free of charge in the first three years after the date of purchase. After this period, the replacement parts are charged to the customer.

Article 5 Submitting a claim

5.1 Claims under this guarantee must – with presentation of the bicycle for inspection – be submitted via the Koga dealer from whom the bicycle was purchased. At the same time, the proof of purchase and/or the proof of ownership provided with the bicycle must be handed over to the dealer.
5.2 If the owner has moved house or the dealer is no longer available, Koga B.V. will, if requested, provide information about the nearest Koga dealer.

Article 6 Liability

6.1 A guarantee claim accepted by Koga B.V. does not automatically mean that Koga B.V. also assumes responsibility for any damage suffered. The liability of Koga B.V. is confined to what is set out in these guarantee conditions. Any liability of Koga B.V. for consequential damage is expressly excluded. The provisions of this condition do not apply if and insofar as they arise from mandatory statutory provisions.
