I use a 17/19 Dos ENO with double chainrings (44/42) on my commuter bike with fenders. No chainline issues, the rear brake pads always line up (because the number of teeth total is the same for both combinations), and I have a "headwind gear" on those afternoons when I need it. It works well and I'm very satisfied. The ONLY reason I bought the Dos ENO was because flipping the wheel on a fendered bike is a PITA.

Only really a problem with track ends, though.

Hey guys, tons of most valuable info here, I really have to chew myself through your answers word by word (especially because this is a new horizon for me). Thanks a lot!!!
Initially I thought I would go for the DOS ENO so that I won't have to flip the back wheel in order to change the ratio. But you tell me the smart thing is to run free on one side and fixed on the other. I will not die, I will even enjoy it. O.K. Still, the ENO outlasts and outperforms all the other freewheels, is that right? And what BB and crank would you recommend in the medium price range?

I have read conflicting reports regarding the ENO freewheel in the Bike Mechanics subforum. I got the impression that they are overpriced. I can get 8 or 9 non-ENO freewheels for the same price, and those will for sure last longer than one ENO.

Anyway...

A cheap solution for your cranks would be a road crankset. You can get those really cheap. If you really want to go with a track crankset, the Sugino RD is relatively economical, as it comes with a chainring, too - can be had relatively cheaply from Ben's Cycle.

RD is a road crankset. And I've said this a million times, but don't get it, the chainline is bad.

Haha

That's what happens when hipsters actually want a bike that is practical.

Go buy one and flip it over, you will find inner chainring tabs. Of course, there's not really any such thing as a "road" or "track" crank, but Sugino was selling the RD as a Road Double for years before this whole SS/FG thing got going.

The sugino RD has a chainline of 45mm in the outer position when used with the recommended sugino 103mm JIS BB. This "inherent nonsense" can be found on the Sugino web page: https://www.suginoltd.co.jp/singlespeeder_e.html

This crank will have bad chainline unless you use it with the ring in the inner position with a longer BB.

Any source rookies can check in order to learn the parameters and compatibility/incompatibility of track cranks and BBs ?

Huh? What do you mean incompatibilities. Use the recommended BB for your crank and you can't go wrong.

So, a SS commuter bike with rack, fenders, and multiple lights makes me a hipster?

No. Obviously, operator implied that you are a hipster for some other reason. What, I don't know.

I'd like to add that a hipster with practicality in mind, is a living contradiction - it just cannot be.

Sorry for an OT comment but you can get the ENO (UNO) freewheel on eBay for less than $60 shipped. That makes it worth 2-3 non-ENO freewheels.

I admit I expected a higher price than $60 (wasn't it close to something like $89?). Anyway, I have a source of german-made freewheels, 9 EUR a piece.

And even the other freewheels are much cheaper than $20-$30. Now you're inflating the price of the non-Eno stuff - not fair.

MSRP is $89 for the ENO freewheel but you can do better than that on eBay. As for my inflating the price of non-ENO stuff, you're right about that so your ratio of 5-6 may be correct. However, $60 for a nice freewheel isn't a bad deal!
