Higher Perspective Wheels
The HIGH PERSPECTIVE WHEELS have internal bushings to fit 1 1/8 inch control
bars perfectly. Use a length of PVC tubing as a spacer outside the wheel and a
short length inside the wheel as a stop so the wheels don't migrate while they
are rolling. PVC does not come in 1 1/8'' inside diameter. therefore you must
cut the PVC lengthwise to fit it on the base tube. a bit of duct tape of
fiberglass tape around the PVC and next to the stop will keep the wheels
If your base tube diameter is smaller than 1 1/8'', a short 1 1/8'' sleeve
should be used. If it is larger than 1 1/8'', file or bore the bushings to size.
The bushings may be pushed out of the wheel for this purpose.
Note that frequent hard landings may bend the base tube. You can prevent this
by inserting a full length sleeve inside the base tube. Do not use less than
full length sleeves unless you bevel their edges very carefully to prevent their
cutting into the base tube.
