Setup, Compatibility & Care
Installation requires standard flat bar tools and basic cable cutters. Ensure the shifter is positioned on a standard 22.2mm flat handlebar. When installing, use the included SP41 housing; ensure the housing ends are cut square and are free of burrs to maintain shifting precision. Periodically check the cable tension at the barrel adjuster, especially after the first 50 miles as new cables naturally settle. Keep the internal mechanism free of heavy grit by occasionally applying a light bicycle-specific lubricant to the lever pivots. Always verify that your front derailleur is a genuine Shimano Tiagra 4700 model to ensure correct indexing.
