A universal shape allows our valves to effectively seal UST and Road Tubeless, as well as standard tube-type rims. Mercury Wheel's Tubeless Valves are 44mm and have a removable valve core to make adding sealant a breeze, and you won't have to break the bead on your tires if you need to freshen up your sealant. They come in a package of two.
If you're looking to adapt your Mercury wheels to handle a different make/model of cassette cogs - this is the right spot. You're also in the right spot if you've put some miles on your wheels and you're ready to grab a fresh freehub of the same type.
To order a replacement, you'll need to know a little about the drivetrain on your bicycle and the specific hub used on your wheel.
The Hub Model # must match your hubs or the freehub body will not fit correctly.
If you'd like some help determining the right freehub, email a picture of the hub shell to email@example.com.
