1. Make sure the brakes are loose enough to allow the wheel to

pass through the brake pads easily.

Rotors

Some freestyle BMX bicycles come equipped with a detangler system that will allow the handlebar to spin 360-degrees without binding the cables. It is very important that this system is adjusted

to set the bearing for maximum travel. The bearing should be as far down as it can go without resting on the lower plate or the adjusting barrels screwed into the lower plate.

3. Use the adjusting barrels that are screwed into the

2.	Place wheel into fork drop outs.
3.	Install retaining washers with raised lip pointed towards the fork,
	and insert into the small hole of the fork blade.
	NOTE: Some scooters may have step retaining washers in place
	of the retaining washer (shown in dotted box). If so, install the
	step retaining washer, raised portion sliding in to the fork dropouts.
4.	Install axle nut and tighten.
	Make sure the wheel is centered between the fork blades.
5.	Spin the wheel to make sure that it is centered and clears the
	brake shoes. Tighten the brakes if necessary.
6.	Turn the scooter upright using the kickstand to support it.

It is very important to check the front wheel connection to the scooter. Failure to properly tighten may cause the front wheel to dislodge.

correctly. Installation should only be done by a qualified scooter mechanic with the correct tools.

Upper Cable

1.First connect the barrel end of the upper cable to the rear brake lever. Make sure the long cable casing is on top of the short cable casing; otherwise, the upper cable will have a twist in it.

2.Route the upper cable through the handlebars (below the crossbar) with the short cable casing on the same side as the rear brake lever.

3.Connect the upper cable to the upper plate by passing the football ends of the upper cable through the threaded holes in the upper plate and connecting them to the bearing.

4.Screw the adjusting barrels into the upper plate. Don’t tighten the locknuts at this time.

Lower Cable

1.Slide the cable casing through the cable guide on the frame.

2.Connect the lower cable to the lower plate by passing the football ends of the lower cable through the threaded holes in the lower plate and connecting them to the bearing.

3.Screw the adjusting barrels into the lower plate. Don’t tighten the locknuts at this time.

4.Connect the lower cable to the rear brake. Don’t adjust the rear brake at this time.

NOTE: Check to make sure all 11 cable casing ends on the upper and lower cables are seated correctly, and that the spring tension of the rear brake is pulling the bearing down.

Adjustment

1.Screw the cable adjusters on the rear brake lever and the upper cable splitter all the way in.

2.Screw the adjusting barrels in the upper plate in (or out)

upper plate to make the bearing parallel to the upper

plate. Use a 10mm wrench to tighten the locknut on the

left adjusting barrel of the upper cable. Leave the right

adjusting barrel loose.

4. Screw the lower cable adjusting barrel into (or out of)

the lower plate until they are as close to the bearing as

they can get without touching it.

5. Screw the cable adjuster on the upper cable splitter out

until all slack is removed from the upper cable. Then

screw the cable adjuster out one more turn to raise the

bearing an additional 1mm away from the lower cable

adjusting barrels.

CAUTION: Don’t screw the cable adjuster on the upper

cable splitter out more than 8mm. Use the cable adjuster

on the rear brake lever if more adjustment is needed.

6. Check for bearing flop by placing the handlebars in the

normal riding position, then quickly rotate the handlebars

back and forth. Perform the following steps to eliminate

bearing flop.

NOTE: The bearing should never be allowed to rest on

the lower plate or lower cable adjusting barrels.

a) Screw the lower cable adjusting barrels out of (or

into) the lower plate until all bearing flop is eliminated.

b) Tighten the locknut of the right adjusting barrel on the

lower cable.

c) Rotate the handlebars 180 degrees and recheck

for bearing flop. If there is any bearing flop, use the

“loose” adjusting barrels on the upper and lower cable to

remove it.

d) Repeat steps (6a) and (6c) until the handlebars can be

rotated 360 degrees without any bearing flop.

7. Finish adjusting the rear brakes.
