Chain guides & Tensioners

The Chain Keeper is a guide to keep your chain right where it belongs. Mounted in place of a front derailleur, the Chain Keeper works with single chain ring drivetrains using a narrow chain. The chain block surrounds the chain as it meets the chain ring and prevents it from skipping off.

Note: This is not designed for downhill, freeride, or big hit use.

Want to build a single speed without having to buy a dedicated frame? Try the Melvin. The Melvin bolts to the frame where the rear derailleur would normally go and allows the use of a single speed rear wheel on bikes with vertical dropouts.

The Melvin uses two pulleys, just like a rear derailleur, which gives it 20 teeth of chain wrap. This means that the Melvin will work with multiple front chain rings while maintaining proper chain tension. Of course this is no longer a true single speed, but can come in handy when two or three gears are all you need. Twenty teeth of chain wrap means that chain rings with a maximum difference of twenty teeth can be used up front.

Chain tension is optimized when the chain length is cut so that the pulleys are aligned vertically. For 1/8" cogs Paul recommend the silver SRAM PC-1 chain and any 8 speed chain for 3/32" cogs.

LOW SWEEP for 34-52T chainrings.

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. LoneWolf Aero Chainguide was also ridden to victory through truly epic conditions at Unbound Gravel 2023.
We think of this little chainguide as 30g 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.

• 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-62T based on frame; Low sweep for smaller chainrings in that range will be most popular
• Head has 8mm of adjustment for chainline via our GuideLock quick adjustment system

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 in the 2023 Giro d'Italia.

Compatibility

• Chainring Compatibility - Mid Sweep 48-52T round chainrings
• Compatible with Cervelo S5 and P5 bikes that have a braze-on front derailleur mount
• Mounts directly to the frame in place of the braze-on
• Only for use with 1x drivetrains
• Head has 8mm of adjustment for chainline via our GuideLock quick adjustment system

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
