BICYCLE MAINTENANCE
We would like to remind you to do a proper maintenance to keep your bike in a good condition.
Regularly check if all screws of your bike are properly tightened.
CRANKSET AND PEDALS
After the first 20 km tighten the crankset and also tighten the pedals to the crank arms. Check if crank
bolts are properly tightened.
IMPORTANT WARNING
No check of crank arms fastening to the bottom bracket axle may result in progressive release of crank arms
and cause irreparable damage to the crank arm. Such damaged crank arms must be replaced with new crank
arms. Please contact special bike service for crank arms replacement. Pedals must be firmly fastened in
crank arms. Check tightness of pedal fastening regularly otherwise pedals may release progressively and
thread inside of crank arm will be damaged. Above mentioned damages are not covered by warranty.
PEDALS ASSEMBLY
Pedals are generally marked on the axle of each pedal by letters R - right pedal and L - left pedal.
1. First lubricate the thread on pedals with grease before assembly.
2. Screw the right pedal (R) into the thread of the right crank arm (arm with chainwheels) by turning it
to the right.
