LoneWolf Aero Chainguide for Cervelo
Eliminate Dropped Chains
The LoneWolf Aero Chainguide is a lightweight, sleek, reliable option to prevent dropped chains in road, gravel, and CX races. Think of it as 30g of insurance, where a dropped chain could cost you a shot at the podium.
Trusted In Cycling’s Biggest Races
Team Jumbo-Visma trusts the LoneWolf Aero Chainguide on their team bikes. It prevented dropped chains on the storied cobbles of Paris-Roubaix, won the Giro d’Italia, and is on board for The Tour de France. It was also on the winning bike at Unbound Gravel 2023 in some truly epic, muddy conditions.
Designed For 1x
The LoneWolf Aero Chainguide is compatible only with bikes that have a 1x drivetrain. This is because it uses the mount in place of a front derailleur. It can be paired with round and oval chainrings on road, CX, and gravel bikes.
Adjustable Coverage
The head of the LoneWolf Aero Chainguide must be within 2mm of the chain to be effective at preventing dropped chains. Three base sweep options cover the vast differences in chainring diameter from 38-62T. Low sweep is for roughly 38-52T chainrings, mid sweep is for 52-58T, and high sweep is for 54-62T. Our unique GuideLock quick adjustment system provides 8mm of positioning for chainline.
