The new Wolf Tooth Components LoneWolf Aero Chainguide has been tested by pro road team Jumbo-Visma (at Roubaix, Giro, and will be raced at Le Tour, too) and at this year’s Unbound, which had a rough muddy start.
It uses a machined alloy body with replaceable plastic guide that sits close enough to the chain to prevent it from bouncing off, negating the need for a full shroud.
Designed specifically for 1x road, gravel, and cyclocross setups, it attaches to your frame’s front derailleur braze-on mount and is compatible with round and oval chainrings from 38-62T. Wolf Tooth also offers clamps for metal bikes with round seat tubes in 28.6, 31.8,
and 34.9mm diameters that lack a braze-on mount.
Three sizes are offered to fit that spread of chainrings, with up to three bolt positions to combine with the vertical adjustment of the braze-on’s bolt slot allowing you to position the guide 2mm above the chain. Options are:
- Low Sweep – 38-52T
- Mid Sweep – 54-58T
- High Sweep – 60-62T
A shim-free adjustment bolt allows inboard/outboard adjustment to position it 2mm off the inside of the chain, with 8mm of total chainline adjustment. A separate bolt controls the angle, letting you rotate the guide to provide maximum “coverage” of the chain.
For Team Jumbo-Visma (and you, if you own a Cervelo P5 or S5), they offer a special version to fit that frame’s unique braze-on mounting position.
Available now direct and at your local bike shop for $39.95, in black only. Claimed weight is 29g to 33g.
