5/Bearing Adjustment - Decathlon BTWIN User Manual And Guarantee

CAUTION
When you intend to change speed, continue pedaling normally without forcing,
push the gear changer switch until the chain is in place on the chosen crown or
spindle, if your gear changers are not indexed.
Each clog on the switch corresponds to a position on the spindles. If the chain
tends not to go up or down quickly on the spindle, stretch the cable turning the
adjustment cylinder located on the switch all the gear changer, anticlockwise.
If the chain tends not to go up or down too quickly, turn at the cylinder clockwise.
The spindle must be changed fluidly

5/Bearing adjustment

The fork is responsible for holding the front wheel of your bicycle. The headset is
the bearing system, which allows the steering of your bike by the rotation of the
fork, the stem and the handlebar.
There are several areas on your bicycle containing bearings that must be
adjusted and/or lubricated. Proper maintenance in these areas will insure longer
bearing life, and easier and safer riding of your bicycle.
Proper adjustment of these bearings requires special tools and knowledge. We
suggest these adjustments be made by a qualified repairman. Please see instruc-
tions below for checking if bearings need to be adjusted. If so, follow these
instructions:
1. Put the key washer onto the fork stem so it is down as far as possible. The
small tab inside the key washer must fit into the slot on the fork stem.
2. Thread the lock nut onto the fork stem by hand.
3. If there is front to rear play in the headset tighten the adjusting cone, then
secu- rely tighten the lock nut.
4. To check the headset for proper tightness, bounce the front wheel on the
ground and turn the wheel from side to side. If the fork binds, it means that it's
(too tight). If the fork shifts, it's (too loose). Loosen the lock nut, readjust the
adjusting cone, and then re-tighten the lock nut.
Danger:
An over tightening of the stem-to-fork assembly bolts can make irreversible dama-
ges in the steering tube and may provoke an accident that can cause serious inju-
ries or death (can pull a blocking or a breakage of the movements, damage the
tube of direction...)
To avoid an over tightening, please respect the torques given in the "Assembly
and adjustments" chapter.
