The VR30 suspension system has more benefits than just the comfort of suspension. Up
until now, it was often difficult to transport long wheelbase
recumbents that were longer than typical upright bikes. Tan- Swingarm dem racks often were needed. The Metro has the ability to
fold itself into two positions; fully folded, with the rear wheel tucked under the frame for a "minimized" storage size, and partially folded. When partially folded your metro should fit standard bike racks.
Wing Nut
System Pre-Load
To have the suspension operate best, you need to set the
"pre-load" on the elastomer to suit you weight. This is very Suspension Wing Nut easy to do. Simply make sure that the elastomer clamping wingnut is loose. If it is not, then loosen it completely. Then sit on the bike, reach under the seat and turn the wingnut in until it just starts to tighten up against the elastomer. That's it! Now the suspension pre-
load is correctly set for your weight.

Derailleur and cassette as seen from rear of bike
If your bike uses the Sachs 3X7 system for 21 speeds, you have a rear derailleur and cluster in addi- tion to the internal 3 speed. The
rear derailleur on your Metro is an indexed system, shifting up and down in preset intervals corre- sponding to "index" clicks of your shifter. This system requires a little patience to set up, but once it is it
will give a season of proper performance.The rear derailleur
has two limit screws (see manufacturer's instructions for lo- cations), and these must be ad- justed properly before the index system will work. Set the shifter
on the high sprocket end of its travel and adjust the high limit screw so that the derailleur cage aligns with the high sprocket. Repeat for the low sprocket. Now with the chain on the high (smallest) rear sprocket, turn the pedals and shift the shifter up three clicks. The rear derailleur cage should align with the fourth sprocket up from the smallest (see illus- tration). If the derailleur cage is to the right of the proper sprocket (as seen from the rear of the bike), turn the adjustment barrel counterclockwise on quarter turn. If the derailleur cage is to the left of the fourth sprocket, then turn the adjustment barrel clockwise one quarter turn. Turn the pedals by hand a few turns and then look at the alignment again; repeat the adjustment steps until the derailleur cage is perfectly aligned with the sprocket, and the chain shifts effortlessly between sprockets when the shifter is turned between "clicks".

Nexus 7 speed Hub - VR30N
This is an internal 7 speed system built by Shimano. It provides a simple to operate, relatively wide range of gears. We are using the thumb control for the Nexus. To shift gears simply flick the lever with your thumb. Mov-
ing the lever one way shifts to the easier to pedal gears (lower numbers). Flicking the lever in the other direction gives you the faster moving (but harder to pedal) gears. The system requires no maintenance, and shifts very well under all con- ditions.
Nexus Hub Adjustment | Adjust Barrel |
|
This has been set by the factory, but if you have shifting problems it is very simple to adjust. Switch the gear control lever to the "4" position. You will notice that the number "4" is printed in RED. Now look at the right side rear dropout . Just inside the bike frame is a control ring that rotates when you move the shift lever. On this ring is a red mark . There is also a mark on the body of the hub right by the control ring . When the
shift lever is in the "4" position, the red mark on the control ring should line up with the mark on the body. If is doesn't, simply adjust the cable ad- justing barrel until they do.
Sachs 3x7 — 21 speed System
The Sachs 3x7 system is a unique 21 speed sys- tem. It utilizes an internal three speed hub mated to a standard seven speed cassette. The three in- ternal gears give you three ranges of gearing, just
like a standard front chainring and derailleur system. The external seven speed cassette and rear derailleur give you seven speed ranges, for a total of 21 speeds.
Sachs Hub Adjustment - VR30S
Disconnect the adjuster sleeve. Set the left twist grip to the "3" position. Lift the rear wheel and rotate the cranks to be sure the hub is engaged. Slip the adjuster sleeve onto the pull rod just far enough to lightly tension the cable. Be sure you do not drag the pull rod out from the hub axle nut. Lift the back of the bike, and while pedaling, twist the left gear shifter to the "1" position. Make sure hub is engaged. If you don't have smooth engagement between the internal gears, rotate the adjuster sleeve until the system shifts smoothly.
