1) After
removing the original crank set, remove the bearing and leave the
2.5 mm spacer, If there is no spacer on either side of your cranks
you will need to get a wider BB if you have an ISIS BB you must have
a 73mm X 118 spindle length, 63mm X 113 spindle length. Many pure
cross county cranks are not wide enough to accommodate the extra
width needed. Always use grease to lube the threads before reinstalling
the bottom bracket |
 |
2) Install the ISCG
roller plate, if the ISCG tabs are inset over 2mm you may need to
add washer between the ISCG Roller Plate and the frame. A good starting
point to set the angle the Roller Inner Plate is to have the bottom
flat portion horizontal with the ground. Also make sure the Roller
Plate doesn’t interfere with any pivots on the frame. |
 |
3) You will usually
need to add the supplied spacer before reinstalling the bearing with
the normal 2.5mm spacer, but it depends on the application and clearance
of the inner plate and the chain The Dualrailleur Guide comes with
1mm and a 1.5 mm spacer. If you need a spacer try the 1mm first. |
 |
4) Install the Dualrailleur
Guide on the frame as you would install a normal derailleur. There
should be about a 5 - 10mm gap between the Roller Inner Plate and
the bottom of the Dualrailleur. |
 |
5) The inner side if
the Dualrailleur and the Roller Inner Plate should be about equal
this us a good starting point as a inboard adjustment |
 |
6) Reinstall the cranks
making sure there is enough clearance between the bash guard and
the Dualrailleur 3mm – 5mm |
 |
7) Install the chain
as normal remembering to go over the roller. Check you clearance
between the chain and the inner plate 3mm – 5mm, if the clearance
is too great you may need to added spacer/washers between the ISCG
Roller Plate and the frame. |
 |
8) Install and adjust
the shifter cable for the granny gear then shift it into the middle
ring. In the middle ring position the Dualrailleur should set pretty
even with the bash guard. This also depends in the thickness of the
bash guard. Make sure that the Dualrailleur doesn’t interfere
with cranks. |
 |
9) In the middle ring position you should
have about 3mm – 5mm clearance between the chain and the inner
polycarbon inner plate
Remember to adjust the derailleur not to go past the middle ring as
normal
|
 |
|
| 10) Shift the Dualrailleur into the granny
gear the chain should drop as normal. At this point you should be able
to adjust you derailleur as normal. Cycle through the front gears to
insure shifting is smooth
Shift all gears in the rear as you would normally set up a bikes
drive train.
|
 |
|
| 11) It is not unusual for the chain to slightly
touch the inside of the Dualrailleur inner plate In the large gear
on the back cluster
Also slightly touch the outer guide plate in the small gear In the
rear
|
 |
|
| Now the Dualrailleur should be set up also
make sure the chain ride as normal on the lower roller. It should ride
in the inner part of the wheel in the granny gear and in the middle
of the wheel in the middle ring. |
 |
|
| Once the drive train has been set up you
need to check to insure the Dualrailleur has no issues as the suspension
goes through its travel. This can be accomplished by letting the air
out of the shock or removing the spring depending in the type of rear
shock. This has most likely been tested if the bike has been certified
to work with the Dualrailleur guide. Also test the chain growth and
adjust as normal |
 |
|
| At this point the bike should be ready to
rock and roll. You may need to adjust shifter tension as normal if
the cable stretched.
