GUIDE SETUP INSTRUCTIONS
3. Hold backplate directly against ISCG05 tabs. Check for clearance between the backside of the guide and the bike frame (use included 2.5mm spacers if necessary to space the backplate away from the frame).
5. With crankset and chain installed, use spacer shim block to measure the clearance between backplate and chain
6. Determine the corresponding number of chainline shims required
7. If more than 5 shims are required, install the supplied 2.5mm washers behind the backplate and return to step 2
8. Assemble top guide with spacers and tighten the bolt to 3Nm
