Wolf Tooth LoneWolf Aero Chainguide - Cervelo - Mid Sweep

The Wolf Tooth LoneWolf Aero chainguide for Cervelo prevents dropped chains on select Cervelo models when equipped with a 1x drivetrain. This product has been tested and developed alongside Team Jumbo-Visma, who have been racing with this in some of road cycling’s biggest races, winning the Maglia Rosa, Maillot Jaune, and Maillot Rojo in 2023.

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.

Compatible with Cervelo bikes that have a braze-on front derailleur mount. Mounts directly to the frame in place of the braze-on front derailleur mount. The LoneWolf Aero chainguide is compatible only with bikes that have a 1x drivetrain.

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. The unique GuideLock quick adjustment system provides 8mm of positioning for chainline.
