The only thing smoother than the 3/8″ bolts that come stock on most of our hubs are these Volcano Bolts.
These are for pegless riders who don’t need the 17mm wrench flats, and can use just a 6mm allen wrench to tighten up their wheels.
Fits most inbound 3/8" axles, including Odyssey and Sunday.
Sold in pairs.
