Traditionally, the freewheel have been considered a disposable component and one that should be replaced on a regular basis. It is our belief that when you invest in your drivetrain you should expect your gearing to be of sufficient quality and durability to allow more time for riding and less for repairing and replacing components. We set out to create and manufacture a freewheel that would be durable, reliable, and easily maintained.
The ENO is the answer.The freewheel utilizes a sealed cartridge bearing instead of a loose ball system. There are two advantages to the cartridge bearing: It is sealed from elements like mud, grit, and water. Plus, the bearing is nicely contained in one simple unit, easily pulled and replaced when worn.
The ENO freewheel features a machined inner driver and machined outer gear case resulting in a freewheel that runs concentrically without the tight and loose spots common to other freewheels. A 36 point engagement system and a case hardened, nickel electro-plated outer gear case make this freewheel a perfect addition to your single speed.

retro-direct requires two independent freewheels because they need to rotate at different speeds.

Any tips for setup with double rings up front?

Actually, it is PERFECT for double rings up front! the outer-say 46 aligns perfectly (if you have correct BB!) with the outer (16, 18, 0r 20) and the inner 2 tooth lower-44 tooth aligns with the larger, inner cog (18, 20, or 22). This two tooth difference in each of the positions keeps the rear brake pads/disc in exactly the same position. use the low gear for fire roads/headwinds/long climbs/feeling tired days. If no rear brake, I speculate you could go five (but I prefer even numbers in singlespeed gearing for longevity-, so 4 for me as track dropouts allow 3 teeth of "play" front to rear) tooth difference up front. A quick release vintage 5 speed(or Phil Wood) freewheel hub in 120mm opens quick change option!

It is a MUST have for Rivendell Quickbeams! My stock 32, 40 front mated with the 16, 18 rear yields a great 40x16 for my very hilly city commuting and a 32x18 for fireroads.

I have a Surly 0gre with 2 rings 32 & 36 with the WI 17/19 out back and it has worked perfect for years. With a surly tuggnut I swap in 30-45 sec.

What can I say? Stop stripping and cleaning your ACS claws after every wet ride and put on an Eno. I grabbed the dos eno so when it snows I can put on a lighter gear for traction (and to slow me down!).
Heavier, but who cares? Go faster and lose a couple of pounds. You got rid of your derailler anyway...

I am running this on a fixie flip flop hub. One thing to remember is it requires a 3/32" chain. A 1/8" track chain will not fit between the 2 gears and it will climb up to the larger cog.
My chainline seems fine, don't even see a difference.
With that said,whats not to like? It gives you 2 options when riding a single speed whether its a bmx or track bike. Nice for hills.

like others have said, it's solid, but it's bombproof and handles the sludge well. the ability to change gears is nice, as it comes with the additional loving of being a simple single speed...mine is set up on a Sugino XD600 with a 48 and a 46 Sugino ring up front...chainline on a 103 bb is nearly perfect on both lines...

Super Quality Product from White Industries - I guess that's expected. But my Raleigh One-Way with ultegra crank with 2 chain rings seems to have a more precise chain alignment making the drive train eerily silent. I went with 16/18 matched with surly 42/40 chain rings to keep identical chain length while achieving a total 4 tooth difference that is enough to climb a medium steep grade and still be able to get the speed up downtown and on the flats. I am very pleased with this product.

White Industries products are just amazingly designed and manufactured. But I will focus on the freewheel-The teeth are so incredibly hard that my 40 (yes it is Alu. but still) tooth front ring is showing lots more wear than my 16 tooth White rear! I am sensitive to sound and don't find the noise annoying when coasting. The fact that it is rebuildable says a lot. If you are not certain of the size White FW you need, just get a used one or experiment with a "Shi" one. Use http://www.bikecalc.com/gear_ratios to convert the highest gear you can ride with your geared bike on your typical route to pick the White FW you need.
