Make sure you crank arms are installed 180° from each other.
Before installing the pedals, It's very important to apply a conservative amount of grease to the pedal threads. This will ensure the pedals are making a solid seat into the crank arms and help mitigate the pedals from being seized in the crank arm.
The left pedal must go on the left. It is reverse thread, to tighten it, you must properly align it and then rotate it counter clock wise. Counter clockwise to tighten. Do not force it, it should start threading easily by hand when done correctly.
The right pedal must go on the right. It has a standard thread. Rotate clockwise to tighten.
Make sure your fork is on correctly and not backwards (brake caliper and rotor goes on the left side of the bike).
Before installing the fork, make sure wires and cables are routed on the left side of the fork to avoid damage/tension of wires.
You may need to flip (left to right, right to left, front to back, back to front) the handlebars before installing to make sure the wires are not twisted. The display goes on the left.
Do not squeeze brake levers before brakes are installed.
Do not touch the brake rotors with your fingers. The oil can contaminate them and cause them to be noisy when used.
Headset (see 2nd video below), fork, top cap - If you are not familiar with installing this or not familiar with bicycle part names, it may be best to have it assembled by a bike shop. Please watch video carefully.
As with many bike components, proper installation is important to avoid damage to the bike and to avoid injury while riding the bike. If you are unsure, stop, take some pictures and contact us.
Carefully install fork fully, make sure it is seated well with the bottom of the head tube and the lower bearing that is inside the bottom of the head tube. Only the crown race should be on the fork steerer tube at this time. The lower bearings are already in the lower cup at the bottom of the head tube. Along with a dust cover.
Once the fork is installed through the head tube, place the compression ring on the top of the fork steerer tube. The compression ring has a "split" in it. It is not a complete circle.
Slide it down, the lip of the compression ring will insert just inside of the bearing when the fork steerer tube is properly centered. This make take some adjustment to get it to sit just right.
Next place the cone spacer or conical spacer on. Make sure the plastic/ring or dust cover is also installed with this. It should fit right on this spacer.
Add remaining spacers on steerer tube.
Put stem on on steerer tube (but do not tighten bolts yet!). Are you handle bars on correct? Are the wires and cables routed properly?
Insert top cap and bolt, carefully tighten the top cap bolt as shown in the video until you begin to feel resistance rotating the fork, at that point you may even back it off a few degrees. Does it the fork turn smoothly? Does the fork shift up and down relative to the head tube? It should not shift up and down relative to the head tube.
Now you can tighten bolts on stem where it connects to steerer tube. Please be careful and slowly tighten in a crisscross pattern. Do not over tighten or you may strip the stem.
Check to make sure, there is no "play" in the fork. If the fork is properly seated and tightened, the fork should not shift up and down relative to the head tube of the frame.
Assembly Complete? Now is a great time to:
Tune your derailleur with bike off and verify hanger is straight:Click Here
Failure to do this may cause damage to your rear wheel, power cable, derailleur, and derailleur hanger.
