With crankset and chain installed, use spacer shim block to measure clearance between back plate 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 bolt to 3Nm
