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.

And what’s so “aero” about it?

The plastic guide is clearly based on some Naca profile, certainly chosen on the basis of testing different profiles in the wind tunnel for hours and hours by Wout Van Aert.

What happens if you peddle backwards or push your bike backwards, the chain comes off the bottom of the chainring surely?

It can, though it takes some unusual circumstances to cause this – lots of bouncing and backpedaling. Generally the drivetrain is spinning forward and if the guide/guard is working properly the chain feeds back onto the chainring if it’s rotated forward.

Jumbo used this when the infamous chain drop at the ITT climb at the decisive stage of the Giro happened?

If you watch the follow cam footage closely, the chain actually came off the top cassette (he was riding in the biggest cog) and went into the wheel. You can briefly see roglic pick it up out of the wheel and spin it back on to the cassette quickly

Front derailleurs a waste of what, 50-70 watts? So yea I can see the aero savings

My sarcasm detector might need calibration. Can’t tell if you’re being serious.

Partly serious. It not much but I reallllllly want to know the aero disturbance of a front derailleur.
