This derailleur has an optimised cage shape design so that very little adjustment is required when mounting to a road bike with a wider rear hub spacing (disc brake frames), but is equally compatible with standard caliper brake frames; it provides exceptional shifting efficiency regardless of the bike it is fitted to. Thanks to the enhanced design, Shimano has designed this front derailleur so that it is compatible with most cable routing options on the market; it also comes complete with a, integrated cable tension adjustment screw to ensure excellent adjustability and convenience when fine-tuning.
