WHEELS AND TYRES

The wheel consists of the hub, the spokes and the rim. The tyre is mounted onto

the rim so that it encases the tube in the case of the most common system, i.e.

the clincher or folding tyres. There is a rim tape running around the rim well

(e) to protect the sensitive tube against the edges of the rim trough, which are

often sharp.

Another common system comprises tubeless tyres which require specific rims

without boreholes and firmly screwed valves. Another system comprises in rare

cases tubular tyres which are glued on specific rims.

The wheels are subjected to considerable stress through the weight of the rider

and any carried luggage as well as through bumpy road surfaces and terrain.

Although wheels are manufactured with great care and delivered accurately

trued, spokes and nipples can lose a little tension on the ﬁrst kilometres. Ask

your BERGAMONT dealer to check and true up the wheels after you have bed-

ded them in over about 100 to 300 kilometres or 5 to 15 hours of use.

After the bedding-in period, check the wheels regularly. It will, however, rarely

be necessary to retighten the spokes (f).

DANGER!

Poorly glued tubular tyres may come off the rim. Risk of accident!

CAUTION!

Truing (retruing) wheels is a difﬁcult job which you should definitely leave

to your BERGAMONT dealer.

NOTE!

Tubular tyres will not be considered any further in the following. Read the

manuals of the rim manufacturer, the tyre producer on this BERGAMONT

info CD and ask your BERGAMONT dealer for advice.

CHAIN MAINTENANCE

Although the chain is one of the wearing components of your BERGAMONT

bike, there are still ways for you to prolong its life. Make sure the chain is lubri-

cated regularly, especially after riding in the rain. Try to only use gears which run

the chain in the straightest line (a+b) between the sprockets and chainrings and

get into the habit of high cadence pedalling.

Chains on mountain bikes with derailleur gears are worn out after approx. 800

to 2,000 km or 50 to 125 hours of use. Heavily stretched chains impair the

operation of derailleur gears. Cycling with a worn-out chain also accelerates the

wear of the sprockets and chainrings. Replacing these components is relatively

expensive compared with the costs of a new chain. It is therefore advisable to

check the condition of the chain at regular intervals.

Your BERGAMONT dealer has accurate measuring instruments to check the

chain wear (c). Replacing the chain should ideally be left to an expert, as this

requires special tools. In addition, you need to select a chain matching your gear

system.

DANGER!

An improperly joined or heavily worn chain can break and cause an acci-

dent.

NOTE!

When replacing your chain, only use appropriate and suitable original spare

parts (d). Your BERGAMONT dealer will be pleased to help you.
