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.

Each of the eight components of the GnarWolf Chainguide can be purchased individually. If something breaks in a crash, save money by replacing just the affected part instead of an entire assembly.

We designed the LoneWolf Aero Chainguide for Ridley to cleanly direct mount to the Ridley Falcn RS, Grifn RS, and X-Night 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 39g 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 optimized chainguide solution.
