TRS D-type guides will accommodate chainlines from 48.5 to 51.5mm

For more information on determining your chainline, please see Chainline explained

For this retention device we adjust chainline using spacers between the chainguide backplate and the frame

Start by opening upper slider

Open the metal clip on the upper slider

Flip the clip open

Release the latch and rotate the upper slider open

Install the guide on the frame with the black T-spacer and the shorter of the two bolts using a T25 Torx wrench

This will put the chainguide at a 48.5mm chainline

Close the upper slider and sight down the front of the guide and chainring

Add the silver spacers behind the T-spacer to center the slider over the chainring as needed

Tighten the fixing bolt to 6N*m

Adjust the upper slider height for your chainring size by loosening the T25 Torx bolt and sliding up or down on the backplate

Center the upper slider fixing bolt in the valley of a chainring tooth and tighten to 0.9N*m
