Summary:<\/strong> Certain Specialized bicycles may use a front derailleur mount that does not use the mounting offset speci\ufb01ed by the Shimano E-type or Sram S3 mounting standard. As a result the XCX E-type chainguide<\/strong> will require a spacer and longer screw in order to \ufb01t those bikes properly.<\/p>\n

Identifying the issue:<\/strong> Both Shimano and Sram specify a 5mm offset between derailleur mounting screws. Certain Specialized frames do not use this offset. This results in the frames being incompatible with the XCX E-type guide as it does have a 5mm offset as speci\ufb01ed by the standard. Many of these frames use a mounting bracket for the front derailleur as shown at right.<\/p>\n

Recommended action:<\/strong> The guide may be mounted to the frame by using a 5mm spacer (not included) under the front mounting position. You may use the spacers that come with the guide for \ufb01ne-tuning the chainline as usual.<\/p>\n

If using an added 5mm spacer and any of the included shims for \ufb01ne tuning, a 20mm front M5 mounting screw should be sourced and used to ensure proper thread penetration of the front screw.<\/p>\n
