Wolf Tooth Lonewolf Scott Foil Aero Chainguide

We designed the LoneWolf Aero Chainguide for Scott Bikes to cleanly direct mount to the Foil in place of a front derailleur when running a 1x drivetrain.

The LoneWolf Aero Chainguide prevents dropped chains on road, gravel, and CX bikes with 1x drivetrains. This chainguide has been tested and developed with Team Jumbo-Visma, has been trusted in road cycling’s biggest races, and ridden to victory in the 2023 Giro d'Italia and the 2023 Tour de France. LoneWolf Aero Chainguide was also ridden to victory through truly epic conditions at Unbound Gravel 2023 and 2024.

We think of this little chainguide as 35g of insurance for races where a dropped chain could cost you a shot at the podium. The LoneWolf Aero Chainguide is similar to our existing GnarWolf, and combines a low-profile head that only covers the top and inboard side of the chain with our GuideLock quick adjustment system. This eliminates the need for shims and gives you security in a light, easy-to-use, and aerodynamically optimised chainguide solution.

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 On Cycling’s Biggest Stage
Team Visma | Lease a Bike trusts the LoneWolf Aero Chainguide for extra security on their team bikes when running a 1x setup. It has prevented dropped chains on the cobbles of Paris-Roubaix, racked up wins at the Giro d’Italia, Tour de France, and Vuelta a España, and has been ridden to victory in the mud and grit of Unbound and the Gravel Earth Series.
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. Our unique GuideLock quick adjustment system provides 8mm of positioning for chainline.
