MASH x Phil Wood Hubset

The double-fixed design features threading on both sides of the rear hub, allowing you to mount a fixed cog on either side. This is particularly useful if you want to run two different gear ratios—for example, a lighter gear for climbing or city riding and a heavier gear for track use—and simply flip the wheel around to switch between them.

These hubs are designed specifically for track and fixed-gear frames with 100mm front and 120mm rear spacing. They will not fit standard modern road frames, which typically use 130mm or 135mm rear spacing.

Phil Wood hubs are renowned for their weather resistance. They utilize high-quality sealed cartridge bearings and precision-machined aluminum shells that are built to keep contaminants out, making them an excellent choice for year-round commuters and riders who don't shy away from the elements.

Because these are bolt-on hubs, you will need a standard wrench to secure the wheels to your dropouts. While the sealed bearings are incredibly durable and rarely need attention, Phil Wood hubs are designed to be serviceable if you ever need to replace bearings or clean the internals down the road.

While the rear hub is designed as a double-fixed track hub, you can technically mount a freewheel on one side if the threading matches. However, these are optimized for fixed-gear riding, and you should ensure your setup is compatible with the specific threading standards of the hub.
