Handlebar; Stem And Headset - Biomega BOS Manual

HANDLEBAR

Depending on your model of bike, there are several ways to adjust your handlebar.
BOS
Adjust the handlebar height by loosening the stem. Carefully loosen the two bolts on the side of the stem with a 6mm Allen key. Then use a 14mm
spanner and loosen the top bolt. You can now align the stem with the front wheel. When finished, retighten all bolts. The handlebar can be tilted
forwards or backwards. Loosen the four bolts on the front of the stem, and tilt the bar forward or backwards. When you have found a suitable position,
retighten the bolts.
NYC
To align the handlebar with the front wheel, loosen the stem clamp bolt situated on top of the handlebar with a 5mm Allen key. Align the handlebar with
the front tire; retighten the stem clamp bolt hard enough so you cannot turn the handlebars when you are holding the wheel between your legs.
It is possible to raise the handlebar on a New York. You can order a steering tube adapter e.g. made by BBB (www.bbbparts.com). The size you need
is the following: BHP-20, size: 25.4/22.2. However be aware that any accidents or problems from raising the handlebar are NOT COVERED BY THE
WARRANTY.

STEM AND HEADSET

Depending on your bike, there are several ways to adjust your stem and your A-headset
BOS/BOSTON
Carefully loosen the two bolts on the side of the stem with a 6mm Allen key. Then use a 14mm spanner and loosen the top bolt. You can now align
the stem with the front wheel. When finished, retighten all bolts.
NYC/NEW YORK
To align the Biomega stem with the front wheel, loosen the stem clamp bolt situated on the side of the stem with a 5mm Allen key, align the stem with
the front tire, retighten the stem clamp bolt hard enough so you cannot turn the handlebars when you are holding the wheel between your legs.
LOOSE A-HEADSET
If you experience a loose A-headset or your stem is out of alignment with the front wheel, the procedure is as follows: loosen the bolt that is placed on
the side of the stem (stem clamp bolt), where it clamps the stem to the steering tube. Then turn the A-headset tension bolt placed on top of the stem,
half a turn clock-wise at the time, until there's no play, when rocking the bike back and fort while blocking the front brake.. Now you align the
stem with the front wheel and retighten the stem clamp hard enough so you cannot turn the handlebars when you are holding the wheel between your
legs. Retighten all loose bolts.
