Setting the Toe (front wheel alignment)
First, this setting is very important as it directly impacts performance and handling. Any
vehicle with left and right wheels has a setting called “toe.” This refers to the extent to
which the front wheels point towards one another. Toe in means that the front edges of
the wheels point inward slightly. Toe out means they point outward slightly.
The purpose of toe is to keep the steering nice and tight. All bearings have a little slop
in them. By applying a bit of force to the entire system, it's possible to remove that slop.
Too much toe and you cause the tires to scrub. This causes premature tire wear and
increased rolling resistance. What you're looking for is just a little bit of toe.
Toe is checked by measuring the distance between the front wheels. Check the distance
between the front of wheels at axle height and then at the rear of the wheels at axle
height. The measured distances should be the same or 1/16th of an inch closer in the
front; a very slight toe-in.
This can be done with a tape measure or a Catrike Calibro tool. Make sure to have the
wheels point straight ahead using either method. When using a tape measure, it is best
to measure from the centerline of the tire to the centerline of the other tire at axle
height (approximately 9 ½” off the ground). First measure the front, running tape
measure just under the boom at axle height, then, measure the rear, running the tape
measure just under the bottom of seat frame at axle height. (See images below)
For measurement using the Catrike Calibro tool, use the same method but you can get
more accurate by measuring from the inside of the rim to the inside of the other rim at
axle height using the telescoping feature of the Calibro. (See images below)
