There are three bash plate options: 28T-30T, 32-42T, 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 9: INSTALL BACKPLATE
