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.
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.
Find the right braze-on mount fitment for your bike:
The low sweep mount is designed to have significant adjustment and will work for the most commonly used chainring sizes on most frames. We also offer mid and high sweep mounts for applications where the chainring size is larger than what the low sweep mount can accommodate. The chainring sizes that each mount fitment can accommodate varies somewhat on different frames because the position of the braze-on mount relative to the bottom bracket is not a universal standard. This calculator was developed to determine the chainring adjustability ranges for each braze-on guide based on the specific geometry of your bike.
There are three dimensions that will determine the chainring size range covered by each guide option for your bike. The width of the braze-on slot (A), the distance from the center of the bottom bracket to the lower end of the braze-on slot (B), and the seat tube angle (C). Enter these three dimensions along with the chainring size you plan to use in the blue input boxes to calculate the results for your bike. Guides and fitments that will work on your bike will be highlighted in green; options that will not work will be highlighted in red.
