I like the idea of aluminum because I owned an aluminum Specialized Sirris which was light and fast.

Wondering if the Black Label is practical as a city/pub/every day bike. Is the geometry too aggressive maybe? My last single speed was a Fuji Feather with flat bars. Very comfy.

Maybe I should get a 4130 instead?

And what’s the diff between V1, V2 and V3 of the Black Labels?

Imo....... the State 4130 would make a better "city/pub/every day bike".
For $471CDN the Porter by Moose Bicycles might be an option.....and Free shipping (in Canada) too!

Most of the State frames I have come across have not had great alignment. The 4130 being made of steel lets you safely bend the frame into proper alignment, unless the alignment issue is one dropout sitting higher than the other. The 4130 also gets you more tire clearance, plus rack and fender mounts.

The main upgrade on the Black Label is a full carbon fork. Carbon shaves weight, dampens vibrations resulting in a bit smoother ride, but is less impact resistant, and is less recyclable than a steel fork. It is essential to use a torque wrench on the stem bolts when dealing with a carbon steerer tube. If you crack the steerer tube, you need a new fork.

Plenty of people use track bikes with aggressive geometry as their everyday bike. I'd rather prioritize tire clearance and fenders.

Black Label Single Speed has been a great bike for me, and absolutely works as an everyday bike. I have the V2, and the new one is the V3, and just some small differences between each generation.

Very lightweight, reliable and smooth. After changing to your preferred tires and pressure, and preferred gearing for your use case, you’ll be good. Seems to be lighter than many of the other options and brands, and that was a high priority for me, to increase the fun factor!

I mean I wouldn't want that sort of bike for everyday usage. I want a practical fixed gear or single speed road bike or hybrid. I think looking cool is fun but practicality is more important as a daily driver.

Something with a slightly more neutral or upright geometry would make sense and having fender and rack mounts will be even more helpful and barring that at least some wider tire clearance so less chance of flats and more comfort.

The Cinelli Tutto (which is based off of the Mash Work they made with MashSF for a bunch of years) would be a great bike. I love mine and it is quite a handy bike. I put a nice front canti mounted rack on it but the new version has rear rack mounts and fender mounts and has a derailleur hanger so if you did want to convert it to a multi speed bike it would be pretty easy. I think that sort of practicality is the way to go. Then over time you can decide what fixed gear you want to build and build a dream bike for other riding that isn't commuting and grocery getting and such. That is sort of what I did-ish though I don't really commute much on single speed anymore but I have a lot of bikes and some I built up more specifically for excellent commuting.

Just looked up the Black Label V3. I'd get that one in a heartbeat. In purple.

I've ridden fixed-gear bikes (and high-end road bikes) since the 1960's, and my all-time favorite bike is a Specialzed Langster.

The Langster has a double-butted aluminum frame and fork, with road bike geometry. The Black Label has a carbon fork, so it's even lighter, but otherwise it likely rides the same as mine. Specialized dropped the aluminum version of the Langster years ago, so if I had to replace it, I wouldn't hesitate to get the 6061 Black Label.

I paid about the same for the Langster when it came out in 2006 as the 6061 Black label costs now. With the upgrade to the carbon fork, that's an insanely good deal.

Editing to add:

When I got the Langster, I immediately installed bullhorn bars (much better than drop bars for climbing and accelerating), time-trial brake levers (for the bullhorns), and bolt-on aero bars. I strongly recommend all three changes, although the aero bars aren't absolutely necessary. I do a lot of rides of 3 to 4 hours on the Langster, and the aero bars help a lot.

Love my Langster too!
Mine's a 2009 with a raw aluminium finish and carbon fibre fork. I also swapped the drops for bull-horns with TT levers.

The 6061 Black Label V3 has road bike geometry and clearance for 38-mm tires, as well as the lighter frame and fork.

I did a search and found some reports of frame alignment issues, but all the reports concerned their steel bikes. I wouldn't worry about the alignment of the aluminum Black Label bikes.

Good tip on the torque wrench. I hope the OP takes it to heart when the bike arrives.

No issues with frame alignment for my Black Label V2. Everything was dialed in, and has worked well as a road bike. Regular 40-60 mile club rides with roadies, and I choose the gear ratio of my single speed freewheel based on the route and hill climbs for the particular club ride. The other riders think I’m crazy to ride a single speed, but to get a comparable weight geared bike I’d need to spend $4-5k+. With the low weight, I can keep up except when the speed of the pace lines or the climbs are too extreme.

I have a purple V3 Black Label and absolutely love it. It does feel very responsive, but that makes it feel fast. It is about 18 lbs, and you can feel how light that is. I ordered the GTR carbon wheels for it, and they definitely add to the track feel of the bike. The wheels are holding up well to all sorts of urban and light trail use. I can see the appeal of a steel "pub" fixed gear, but if I could only have one, it would be the Black Label. The value is incredible, and the bike is clean, straight, and with very nice welds. Best of luck!
