Wolf Tooth LoneWolf Aero Braze-On Mount Chainguide

The new 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.

We think of this little chainguide as 30 g of insurance for races where a dropped chain could cost you a shot at the podium. The LoneWolf Aero Chainguide is similar to Wolf Tooth's existing GnarWolf, and combines a low profile head that only covers the top and inboard side of the chain with Wolf Tooth's 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.

Compatible with bikes that have a braze-on front derailleur mount. Only for use with 1x drivetrains. Works with round or oval chainrings. Three base sweep options for chainring sizes ranging from roughly 38T - 82T based on frame; Low sweep for smaller chainrings in that range will be most popular. Head has 8 mm of adjustment for chainline via Wolf Tooth's GuideLock quick adjustment system.

Metal bikes with round tubing that do not have a braze-on mount for a front derailleur can use LoneWolf Aero Chainguide by pairing it with a braze-on front derailleur clamp found on the Replacement Parts page.

Note: Braze-on mount is not at the same height on all bikes so max chainring size will vary somewhat depending on frame brand and model.
