Gearhubs - Biomega BOS Manual

PAD WEAR
Over time you will have to compensate for brake pad wear. See in the manual of your brake how to adjust for pad wear.
A pad should be replaced when its total thickness is less than 3 mm.
Only replace the pad with an original pad. Always use original parts when replacing any part on your bicycle. Failing to do so may cause the different
parts on your bicycle to not work correctly together, which can cause the bicycle to malfunction.
BRAKE LEVERS
Your brakes must be fully applied when the lever is half way to the handlebar. The force it takes to lock a wheel might be less than you think, so do not
use unnecessary force to pull your brakes when you are riding or standing still.
The lever is adjusted in relation to the handlebar by loosening the lever clamp bolt close to the handlebar. Biomega recommends you set the break
levers at a 45°angle downwards. Retighten all loose bolts to 5Nm.

GEAR HUBS
Before every ride you should make sure that your gears are adjusted properly. If the gears are not adjusted properly it can cause a sudden change of
gear.
NYC 700c is equipped with a 2-speed mechanical automatic gear hub. At a certain speed, the hub shifts into second gear automatically. When drop-
ping below that speed, the hub shifts back into first gear. Please reduce the pedal load or stop pedaling to support the gear change.
After a stop, i.e. at a traffic light, you will always be in first gear to start.
WARNING: Excessive heating of the internal gear hub caused by back pedal braking may result in loss of lubricant and can cause harder braking or
lock-up the wheel. A wheel lockup might cause you to lose control and possibly cause injury. Relubrication of the brake sleeve with special grease is
then necessary. Please refer to a qualified bicycle mechanic.
