Dirt 3 Chain Catcher Installation Instructions

(K13-201)

Description:

The K-Edge Dirt Chain Catcher series is designed to eliminate chain drop on the lowest chainring due to hard shifts, cross-chain

shifting and or rough terrain while riding.

Compatibility:

The K-Edge Dirt 3 series can be used with triple MTB cranksets compatible with an 'E-Type' or 'Bottom Bracket Mount' front

derailleur utilizing external bottom bracket cups or NON-GXP bottom brackets. This device cannot be used in conjunction with an 'E-

Type' front derailleur as it is mounted in the same location.

Troubleshooting: • • • • • Pad does not get close enough to chain. o Check that the secondary 2.5mm spacers (for 68mm BB Shells only) is placed between the Dirt 3 and BB shell. o Check to ensure that the 2.5mm spacer (normally reserved for an 'E-Type' front derailleur) is not installed with the Dirt 3. Pad rubs excessively with chain and there are no spacers installed. o Check to see if your crankset is compatible with the Dirt 3.
