Chain Keeper on the Arc Model
The ElliptiGO Arc comes equipped with a chain keeper
located to the inside of the chainring. The purpose of the
chain keeper is to reduce the likelihood that your chain will
become detached from the chainring while riding. While it
is impossible to ensure that a chain will never detach from
the chainring, a properly adjusted chain keeper should
prevent most potential chain detachments from taking
place. The chain keeper is properly adjusted when there is
between 1 and 2 mm of space between the lowest face of
the chain keeper and the inside edge of the chainring.
Adjusting the Chain Keeper
To adjust the chain keeper, follow these steps:
1. If the chain keeper is contacting the chain or chainring,
cycle the drivetrain by hand to identify the point in
the stroke where the chain keeper contacts the chain
or chainring. Once you have located the
point where contact is being made, keep the cranks in
that position for the remainder of these steps.
2. Insert a 4mm Allen wrench into the chain keeper fixing
bolt and turn it counter-clockwise to loosen the bolt.
3. Move the chain keeper away from the chainring until
there is a gap of at least 1mm but no more than 2mm
between the inside edge of the lowest face of the chain
keeper and the inside edge of the chainring.
4. Using the 4mm Allen wrench, tighten the fixing bolt to
6-8 Nm.
5. Re-check the gap between the lowest face of the chain
keeper and the chainring to ensure it is between 1 and
2mm wide.
WARNING! A properly adjusted chain keeper is a
critical safety feature. It is your responsibility to ensure
that it remains set at the appropriate distance from
the chainring. Failure to do so could result in a chain
detaching from the sprocket unexpectedly during a ride.
This could cause you to lose control of the bike and suer
a fall.
