ACS (Anti-Chain Suck) Installation Instructions
(K13-240)
Description:
The three most common types of chain suck for a mountain bike are (assuming no damage to the drivetrain):
1) Excessive chain 'slap' - When a chain has too much 'slack' underneath the chainstay of the frame and is ridden over rough
terrain, large amounts of movement of the chain will occur, this referred to as chain slap. During moments of pedaling this chain slap
can allow the chain to be caught between the frame's chainstay and the chainrings of the crankset resulting in the chain being
'sucked' up.
2) Shift Ramp Snags - When a shift is initiated by the front derailleur and the chain is in transition from a small ring to a larger ring,
the shift ramps that are designed into certain chainrings, can catch the chain when being returned to the rear derailleur. During
moments of pedaling this chain slap can allow the chain to be caught between the frame's chainstay and the chainrings of the
crankset resulting in the chain being 'sucked' up.
3) Excessive Mud Build-up - In some circumstances riding conditions can be considered severe such as mud. During muddy
conditions a build up mud and debris between individual chainrings and chainrings and a frame's chainstay can cause a chain to be
'sucked' up.
The K-Edge ACS series is designed to prevent only two of the three most common types of chain suck - chain slap and snags. The
ACS is not designed to stop a chain but rather deflect and prevent a chain from being caught in a situation that would cause an
inevitable chain suck.
Note:
Please be aware of the capabilities of our ACS device and that it is not a chain guide but rather a deflector preventing the chain from
entering a situation of a chain suck.
This device is not designed to come into direct-constant contact with the chain during normal riding conditions, doing so will damage
the ACS.
