Ditch the front derailleur and go faster with the ALM Engineering Ultra Aero Chain Guide — designed for time trial, hill climb, and single chainring (1x) setups where every gram and every millimetre of frontal area counts.

Replacing your front derailleur with this chain guide gives you a significantly smaller frontal area and a cleaner, more streamlined cockpit. At just 17g, it's one of the lightest chain retention solutions available.
