Proper Leg Extension

Chapter 2: (Continued)

Leg length / The Chain

The trickiest part of the VISION set up is setting the proper leg length. Since the front boom moves in and out to set your leg length, the chain will have to be set after we determine the proper boom setting for you.

If possible, set your VISION on a rear wheel type wind trainer. If you don't have access to such a trainer, have a friend hold the bike up behind your seat while you sit and spin the pedals backwards. When the leg length is set properly, you will be pedaling with just a slight bend in your knee at full extension. Take your time - this is a very important adjustment. Most riders start out with the boom set too short. To avoid this, start your adjustment process with the boom out too far and work back in.

Note: adjusting the seat back angle affects the boom length adjustment. Check leg length adjustment after a seat back angle change.

Your 2002 Vision features our new Instant-Adjust system. To set the boom length to accomidate your leg, simply loosen the quick release skewer on the left side of the boom

collar, shown below. Then move the boom to wherever you need it, and retighten the skewer. The boom will move easier if you loosen the QR skewer one turn after flipping it open. Retighten the skewer by turning it back in one turn, and then clamping it closed securely. Make sure the QR skewer closes firmly. See page two for details on the proper operation of quick releases. There is an alignment

mechanism built into the boom collar to keep everything straight.

Chapter 3: (Continued)

Before you start to ride, look at your gears and make sure that you are set in a good gear to start in. On a flat surface this usually is in the middle chainring (up front) and in one of the three largest cogs (on the back). If the bike is not in one of these gears, have someone hold the rear wheel off the ground so you can spin the cranks and shift the gears. Don’t forget that you should only shift when pedaling! As you gain experience you will find yourself thinking ahead and shifting into your favorite “start-up” gear before you come to a stop.

Now let’s get on the bike. I tend to always mount from the left, like on a horse, but the important thing is to establish a pattern and do it the same way every time so it becomes a habit. For underseat steering bikes, starting on the left side, hold the seat back with your right hand. Standing in front of the handlebar and facing the bike, swing your right leg over the front boom. You are now looking

forward, straddling the bike. Reach down and grab the handlebar grips, apply the brakes, and

sit down.

Mounting-Step 1

Step 2 Step 3

For upright steering bikes,

grab the seat back with your right hand, the

middle of the handlebars with your left hand, and move the handlebars forward slightly.

Now step through the space between the seat and the handlebar with your right leg, and sit down on the seat. Grab the brakes and apply lightly. Rotate the handlebars toward you until they hit the fore/aft adjustment stop. Settle yourself into the seat and get comfortable.
