ISCG-05: steps 7-15.

BASH SELECTION & INSTALL INSTRUCTIONS

 

STEP 1: BASH SELECTION

There are three bash plate options: 28T-30T, 32-34T, 36T. Choose the bashplate (1) that matches your current ring size. The Bash guide & the Under Bash come with the 32T-34T bashplate installed.

NOTE: If the 32T-34T bashplate is the right one for your set up, you can skip forward to step 7.

 

STEP 2: REMOVING BOLT KEEPER

Remove bolt keeper (10) from rear bash plate bolt by pushing a 4mm hex through the bolt from the backside of the guide.

 

STEP 3: REMOVING BASH MOUNTING BOLTS

Remove bash mounting bolts (2) using a 5mm hex.

 

STEP 4: BASH PLATE SELECTION

Select desired bash plate (1) and place bash mounting bolts (2) into holes of bash plate.

 

STEP 5: INSTALL BASH MOUNTING BOLTS

Tighten bash mounting bolts (2) to 6Nm using your 5mm Hex key.

 

STEP 6: INSTALL BOLT KEEPER

Reinstall bolt keeper (10) on the rear bash mounting bolt (2).

GUIDE SETUP INSTRUCTIONS

 

STEP 7: REMOVE TOP GUIDE

Remove top guide (5,6) by removing the front guide locknut (11) with a 4mm hex (never adjust the rear T25 bolt).

 

STEP 8: ADJUST SLIDER

Loosen slider bolt (3) counter-clockwise on the bottom left of the sliding backplate (9) with a 4mm Hex key. Set sliding backplate in the highest position & lightly tighten bolt; It will be readjusted later.

 

STEP 9: INSTALL BACKPLATE

Hold backplate (8) directly against ISCG05 tabs. Check for clearance between the back side of the bashplate/guide and the bike frame. Use included 2.5mm washers (4) if necessary to space the backplate away from the frame.

 

STEP 10: ADJUST BACKPLATE

Rotate backplate (8) until slider adjustment bolt is directly above the crank axle and torque bolts to 5Nm using a 4mm Hex key.

 

STEP 11: MEASURING SPACING

Use spacer shim block to measure clearance between backplate (8) and chain.

 

STEP 12: TOP GUIDE SHIMS

Determine the corresponding number of chainline shims required. Place shims onto top guide mounting bolt (7).

Note: If more than 5 shims are required, install the supplied 2.5mm washers behind the backplate and return to step 9.

 

STEP 13: INSTALL TOP GUIDE

Assemble top guide (5,6) with spacers behind it. Tighten the top guide with outer guide (6) in the flipped up position. Tighten guide locknut (11) to 3Nm using your 4mm Hex key.

 

STEP 14: ADJUST TOP GUIDE HEIGHT

Insert a 4mm hex through the hole in the inner top guide (5), loosen height adjustment bolt and lower the tool onto the chain, between the links. Torque to 3Nm to set height.

Note: The chain link cut out on the inner top guide should sit directly behind the last link to make full contact of your chainring. You may need to adjust both rotation of the backplate (Step 10) and the height of the slider to achieve this position.

 

STEP 15: FLIP GUIDE

Flip outer guide (6) down into position using your hand.
