This chain guide is 2-way adjustable vertically and horizontally.
Vertical adjustments are made by loosening and tightening the bolt beside the "Strummer" logo. The approximate maximum vertical adjustment is 25 mm.
Horizontal (closer or further from the bike) adjustments can be made by adding/removing spacers behind the plastic part. We provide 4 spacers (each approximately 1 mm thick). A maximum of 4 mm adjustment can be made.
