MRP SXg Manuals

SXg INSTALLATION INSTRUCTIONS 1) Begin the installation of the SXg by removing your crankset. Remove the chain from the chainring to ease this process. If you have a Shadow Plus or Type 2 derailleur, disengage the clutch or lock the cage in the relaxed position. 2A) Remove the fastener bolt from the upper guide and swing the front half of the guide open. 3A) Attach the backplate to the three threaded tabs around the bottom bracket shell of your frame. ISCG spacers are included with your guide, install these washers between the backplate and frame as needed for alignment (step 5). 4) Reinstall the crankset and chain. Close the upper guide and skid. 6) Align the rear skid bolt hole with the correct position in the backplate. If you are using a chainring size in the middle of the accommodated range (32T for the small SXg, 36T for the large), choose the upper skid position first (some installations may require the lower position). Tighten the rear skid bolt to 4 Nm. 2B) Remove the rear skid bolt located at the rear of the guide. With that removed the skid should swing open and down. 5) To check guide alignment, from above, look directly down on the upper guide and find the joint of the two upper guide pieces and the chainring aligned. Use the ISCG spacers to achieve this. SM SXg LG SXg 5B) Orient the rotational position of the SXg so that the MRP logo on the upper guide is roughly parallel with the ground. Tighten the ISCG bolts to 8-9 Nm for alloy models, 5-7 Nm for carbon.
