How to Install Stem on Stunner LT
- Remove the top-cap and metal protector used for shipping purposes and set aside. You will not need these parts for the installation of the stem. You may also have a plastic protector around it - this is also to be removed.
- Slide the stem over the steerer tube of the fork. The long bolt going down from the stem
into the steerer tube is used to adjust the preload on the headset bearing. This is
important for smooth steering. Adding tension to the bolt will pull the threaded star nut
(which is found wedged inside the steerer tube) upwards, moving the fork crown race
bearing more tightly into the lower headset cup. Alternatively, reducing the tension on
the bolt will back off the bearing preload, effectively loosening the bearing. When you’re
happy that you have the bearing set to the correct level or preload, apply the front brake
only. While holding the front brake on, rock the bike gently back and fore. If you feel any
looseness - it’ll often feel like a slight knocking feeling - then add more preload tension to
the bolt until the looseness stops.
- Now to align the stem with the front wheel. From above, look at your stem, and align it
with the center of the front tire. Once you have it in place, use your 4mm Allen key to
snug up the 2 bolts that attach the stem to the steerer tube. These should be torqued to
5 to 7 Nm.
- Now to adjust the angle of the stem and the handlebar. This uses a cam lever, similar to
that found on a quick release wheel or seat collar. When closing the cam, you should
feel resistance when halfway closed, if you do not, turn the bolt clockwise with your
5mm Allen key. If you feel resistance before the 50% closed position, turn the bolt anti-clockwise with your 5mm Allen key. Once this resistance is found, you can move the
stem angle and handlebar angle to your preferred location and close the cam lever.
How to Install Pedals
- Apply a small amount of grease to the pedal threads
- Note there is a right and a left pedal, they have different thread directions and are labeled with an R and L respectively
- Insert the right pedal into the right crank arm, turn the pedal axle clockwise to tighten, use a
15mm pedal wrench to tighten
- Insert the left pedal into the left crank arm, turn the pedal axle anti-clockwise to tighten,
use a 15mm pedal wrench to tighten
How to Install Seat Post
- Apply a small amount of grease to lower portion of post-
- Open cam lever on seat collar
- Slide post in to desired height (seat post has a minimum insertion lever marked on it,
make sure this line is completely hidden within the frame)
- Close cam lever (cam lever is tight when it has resistance at 50% of closer, then close
all the way)
How to Install Fender and Headlight
- Locate the fender hardware:
- 2x M5x20 bolts (on bottom of the fork)
- M6 Bolt w/ nut on top of the fork
- Attach both fender and headlight to upper mount in the order: Washer, headlight, fork, fender, washer then locknut,
- Attach fender stay eyelets to lower mounts on each side
How to Install Front Wheel
- Locate Quick Release skewer in charger box
- Unscrew one side and remove one spring
- Insert skewer with lever one the brake side
- Slide spring onto a skewer with smaller cone towards the wheel
- Screw on end nut 1 turn
- Remove protector and slide fork onto wheel while carefully aligning brake rotor into the caliper
- With bike upright and weight on the front tighten end nut on a skewer and close cam lever (cam lever is tight when it has resistance at 50% of closer, then close all the way)
Note: If fender is rubbing on wheel,
- Loosen upper mount and adjust the slotted mount to clear the tire.
- If rubbing on the side the metal stay can be bent as needed to clear
