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 a wide range of possible chainring diameters, see the compatibility section to find which model is right for your setup. Our unique GuideLock quick adjustment system provides 8mm of positioning for chainline.
We believe in your right to be able to fix your components. Crashes happen, parts get misplaced, things go bump in the night. All individual pieces of LoneWolf Aero Chainguide are available individually as replacement parts, just like other Wolf Tooth components that have multiple pieces.
