Two speeds. One freewheel. Zero derailleurs.

The Dos ENO Freewheel adds a little flexibility to any single speed rig without over complication. This smart design makes it possible to manually move the chain between two gears, so after a quick adjustment you're well equipped to tackle the ascents or hammer the flats.

Like the standard ENO, the Dos uses a top quality sealed cartridge bearing that keeps out mud, dust and grime better traditional loose ball freewheels. This also means that the bearing is easily replaced when worn, so the Dos ENO outlives disposable freewheels by years and thousands of miles. A precision machined inner driver and outer gear case eliminate tight and loose spots associated with lower quality freewheels. Finally, a 36 tooth engagement system and a case hardened, electroless nickel plated outer gear case provide instant power transfer to the pedals, outstanding protection from the elements, and jaw dropping looks.

The White Industries Dos ENO Freewheel is available in 16/18T (Blue), 17/19T (Red) and 20/22T (Red) sizes. Silver. Made in the USA.

I got this to upgrade my winter bike setup. I put the Surly 1719 dingle cog on one side and the Dos 1618 freewheel on the other (with 44/42t chainrings). This freewheel is replacing a 16t generic Shimano one and the difference in quality is incredible.

It might seem expensive, but for me it should be well worth it - the Shimano freewheel needs to be replaced after one winter, I'd need two of them to get the high/low gearing I want, and I don't have to deal with a removal tool in a vice whenever I want to change gears, so I'll be ahead if this lasts for more than two years.

On a side note, I'm very excited to hear how this sounds with some studded tires this winter.
