Replacing Your Drive Rollers; Direction - MINOURA RDA INTERRIM ERGO Manual

REPLACING YOUR DRIVE ROLLERS

When you first start riding, the Inter-Rim's rim rollers may be stiff and cause the rim to slip. But the
rollers will soften after a few rotations and will impart the proper rim grip. The rubber rollers may melt
or wear by heating from longtime use.
The rim-drive rollers will eventually wear and need to be replaced. When you find that your load force
has diminished altogether or that you feel some vibrations that cannot be avoided through minor
adjustments, then it is time to invest in a "roller replacement set", available from your Minoura dealer.
To remove: Apply a 10mm wrench to the nut behind the pulley while
1
turning the bolt with a M4 hex wrenc h. (see Fig. L)
If you are changing the roller on the Mag unit (left) side, go to step
2
3.
To change the roller on the assistant-roller-unit (right) side, pull back
the pulley and remove the rubber roller.
To remove the pulley on the Magturbo unit (left) side, you must
3
loosen the two bolts that are located on the surface of the Mag unit
with a M4 hex wrench.
Push the Mag unit in the direction of the drive roller to loosen the
V-Belt and then pull out the pulley. (see Fig. M)
Do not remove the bolts that control the
!
tension on the V-Belt.
As you did with the right-side roller in step 2, pull out
4
rubber roller from the pulley. (see Fig. N)
Be sure to replace both rollers at the same time to
!
prevent uneven wear to the rim and to ensure a
more balanced ride.
