Description:

The K-Edge Cross Chain Catcher series is designed to eliminate chain drop on the lowest chainring due to h ard shifts, cross-chain
shifting and or rough terrain while riding. In addition, chain drop on the single chainring cycle cross due to rough terrain.
Furthermore, the Chain Catcher Pad itself is designed to allow for 'bottom' chain derailment without chain drop when back pedaling
is necessary for foot adjustment and will re-align the chain when forward pedaling is resumed.

Compatibility:

K13-020 and K13-021 Cross catchers are compatible with framesets that allow for a 'low' mounting po sition of our clamp (Minimum
of 53.2mm

K13-022 and K13-023 Cross XL chain catchers are compatible with carbon fiber frames that have a 'web' or large 'gusset' between
the down tube and the seat tube of the frame. This 'web' prevents our original cross catchers (020 and 021) from mounting low
enough to be effective.

from the bottom of the cross clamp to the center axis of the crank spindle is required for a 32T chainring).

Installation Steps:

(Installation for Double crank set’s)

1. Place K-Edge Clamp below front derailleur clamp and lightly tighten the clamp bolt.

2. Slide the chain catcher pad onto the clamp and lightly tighten. See image below:

3. Center the clamp on the seat tube and check for proper clearance of chain catcher pad from the chain and chainring. (XL
pads are long enough to make contact with the chainring bolts if not given the proper distance between the pad and the
chain.) The bottom of the pad should sit just below the chain links and should have approximately 0.5mm clearance
between chain catcher pad and chain by sliding the pad towards the chain. See images below for reference:
