The Gears; Gates Belt Drive - Canyon Urban Manual

48 GEARS

THE GEARS

The gears of your bike serve to adjust the gear ratio
to the terrain you are riding on and the desired speed.
In the case of derailleur gears a low gear (chain runs
over the small chainring and the large sprocket) al-
lows you to climb steep hills with moderate pedalling
force. You must, however, pedal at a faster pace or
higher frequency. Downhill you switch to a high gear
(large chainring in the front, small sprocket in the
rear). Every turn of the pedals takes you many metres
forward at correspondingly high speed.
Continue pedalling during gear shifting, however, at
clearly reduced pedalling force. In particular when
shifting through the chainrings, continue pedalling
slowly and without force.
Modern bikes can have up to 33 gears. As there are,
however, overlapping ranges, actually 15 to 18 gears
are usable. It is not advisable to use gears which in-
volve an extremely oblique run of the chain, as this
reduces power transmission efficiency and hastens
wear of the chain. An unfavourable run of the chain is
when the smallest chainring (front derailleur) is used
with one of the two or three (small) sprockets (rear
derailleur) or when the largest chainring is used with
one of the inner (large) sprockets.
In the case of multi-speed hubs and gearbox shift sys-
tems "1" stands for the first, lowest gear. The gears
are shifted through one after the other, if possible
without turning the pedals, at least, however, at re-
duced pedal pressure. The highest number stands for
the highest gear.

Rear derailleur
The Gates belt drive transmits the force to the gear hub
Before you set off for the first time prac-
!
tise changing gears in a place free of traf-
fic until you are familiar with the functioning of
the different levers or twist grips of your Urban
bike.
Always make sure changing gears makes
!
as little noise as possible and is absolutely
jerk-free.
Always wear straight-cut trousers or use
!
trouser clips or the like. This is to make
sure your trousers do not get caught in the chain
or the chainrings, which would result in a fall.
Adjusting the gear hub or the rear derail-
!
leur is a job for a skilled technician.

GATES BELT DRIVE

With the Gates belt drive a carbon drive belt replaces
the usual chain. This works only in connection with
a gear hub. The carbon drive belt is made of carbon
fibres which reduces the weight significantly and
requires less maintenance by offering more smooth
running and comfort than a chain. In addition, the
belt is more resistant to corrosion and the influence
of direct sunlight.
Maintenance and care
Thanks to the carbon fibre surface, the belt remains
free of dirt. Therefore, it will do to clean the belt with
water, if necessary. The carbon drive belt needs nei-
ther lubrication nor oiling.
Check the belt tension
The optimum operation of the Gates belt drive re-
quires the proper tension of the belt. An unusual low
tension can make the belt skip and thus affect the
performance. Too high a tension of the belt will ren-
der the drive sluggish and unnecessarily increase the
wear of the belt and the bearings.
For easy setting of the tension download
i
the Gates Carbon Drive iPhone®-App
(available free of charge in the iTunes® App
Store), use the Carbon Drive Krikit Gauge or the
Eco Tension Tester (available in Europe at pres-
ent).
