Chain - Care and wear

Regular and correct lubrication of your bike’s chain

makes for enjoyable riding and prolongs its service life. It

is not the quantity, but the distribution and regular appli-

cation of lubricant that counts. Clean the dirt and oil off

your chain with a slightly oily rag from time to time

(a)

Special degreasers are not necessary; they even have a

damaging effect.

Having cleaned the chain as thoroughly as possible,

apply chain oil, wax or grease

(b)

to the chain links. To

lubricate the chain, drip the lubricant onto the rollers of

the lower run of the chain while you turn the crank. Once

this is done, turn the cranks a few more times; then let

your MERIDA bike rest for a few minutes so that the lu-

bricant can disperse. Finally wipe off excess lubricant

with a rag so that it does not spatter around during riding

or can collect road dirt.

Make sure the braking surfaces of the rims,

the rotors and the brake pads remain clear of

lubricants, as the brakes will fail otherwise!

For the sake of the environment, only use

biodegradable lubricants. Bear in mind that

some of the lubricant can end up on the

ground, especially in wet conditions.

Chain maintenance

Although the chain is one of the wearing components

of your MERIDA bike, there are still ways for you to pro-

long its life. Make sure the chain is lubricated regularly,

especially after riding in the rain. Try to only use gears

which run the chain in the straightest line between the

sprockets and chainwheels and get in the habit of high

cadence pedaling.

The chains of bikes with derailleur gears are worn out af-

ter approx. 1,000 to 3,500 km or 50 to 125 hours of use.

Heavily stretched chains impair the operation of derail-

leur gears. Cycling with a worn-out chain also acceler-

ates the wear of the sprockets and chainwheels. Replac-

ing 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 MERIDA dealer has accurate measuring instru-

ments to che ck the chain wear

(c)

. Replacing the chain

should ideally be left to an expert, as this requires spe-

cial tools. In addition, you need to select a chain match-

ing your gear system.

An improperly riveted or heavily worn chain

can break and throw you off your bike.

When replacing your chain, only use appropri-

ate and suitable original spare parts
