Shimano Di2

Adjustment and maintenance

If you wish, your MERIDA dealer can also change the

functioning of the Di2 control buttons

(e+f)

. The change

has to be done with a special test device from Shimano

which is also used for troubleshooting.

If you have smaller hands and want to position the le-

vers closer to the handlebars, there are special adjusting

screws on the handlebars. The handling of these screws

is described in the chapter “Adjusting the brake lever

reach on MERIDA road bikes”.

To adjust the rear derailleur shift into one of the middle

gears press the button at the front switch under the han-

dlebars until the control lamp illuminates red

(g)

. The

ﬁne adjustment of the rear derailleur can now be carried

out. Turn the crank and listen to the noise of the chain

while running.

If there is a noise when the chain rolls off, press the front

lever. With every push the rear derailleur moves inward

by one decimillimeter. If the noise gets louder, press the

rear lever.

The rear derailleur moves outwards in steps of one deci-

millimeter. Once the chain runs quietly, press the button

at the switch once again, the red light goes out. Finish by

shifting through all the gears to check the proper func-

tioning.

Carefully shift through the gears until the chain runs on

the biggest sprocket. If the shifting is not smooth, read-

just once again.

Continue turning the crank carefully and make sure the

rear derailleur cage does not collide with the spokes and

the chain does not move beyond the biggest sprocket.

While doing so, press your thumb against the rear de-

railleur.

In principle, the limit stops are adjusted like the lim-

it stops of the mechanical gears

(h)

. Be careful when

shifting to the lowest and biggest gears in order to check

the position of the limit stops.

Make a test ride in a place free of trafﬁc be-

fore you use your new Di2 gears.

Read the operating instructions of the gear

manufacturer on this MERIDA CD-ROM.
