Many single speeds started out in life as track bikes. Track bikes have track geometry and the absence of brakes which makes their use on the road more dangerous. A single speed cyclocross frame would have front and rear breaks. Road or ‘cross tires could work too.

Eccentric BB might be your friend

If you find an all-road or gravel frame with vertical dropouts, an eccentric BB would be a workaround. Phil Wool makes one but they are speedy. Here's another, think I've seen them for $100 retail.

I just weighed it and it's 22.5lbs.
Mash SF list the rack weight at 1.7lbs, so the bike is about 20.8lbs without it.


That is a cool rig, did you do the paint/coat yourself?

No, it's a powder-coating applied by Arcane Moto in Brooklyn.
The finish is called 'Desert-Aged Brass', it looks rough but feels smooth. Very similar texture to the 'crinkle/wrinkle' finishes used on older engine cam covers and ancillaries.
Scratches appear grey/black, so they don't stand out. The fork was done a year after the frame, and it matches perfectly.

After I tired of the metallic-white factory paint job, I rattled-canned it olive green with Krylon. Did the GT-inspired graphics in paint too. The finish didn't last though, paints & clearcoats from a spray can are just so soft.
I refinished it 3 times (it cost me about $10 each time) before finally getting it powder-coated.
A fun chapter of its life though.

Awesome. I love seeing bikes that have seen various incarnations with the same owner. Really says something about the bike and the owner.

Funny, I was looking at the current nature boy. That would be a super fun build for sure.

For sure. I will keep my eyes open for something along these lines. Thank you.

That looks perfect. Nice work.

A used rim-brake Nature Boy is a good shout but modern stuff like external BB is essential to keeping weight down. Carbon fork would do it too.

All-City now offer the Super Professional in flat-bar single-speed. No weight given, but it's a lovely frameset.
You are right that is lovely. I will spend some time looking at this one. Great find.

What wheels are those on the new build?

It's a lot of fun, but the front end handling really quick; not the bike I'd grab for a century even if it were geared. A 35mm juuuuust fits in the back.

My other is an '81 Schwinn Voyageur. It fits me great, but it's regular 4130 and the whole frame is chromed so no lightweight. It might fit 35s, but it'd be tight. It wears 32mm GravelKings.

A friend of mine received a custom Bob Jackson Vigorelli with mid reach brakes last month so it fits 35mm tires. Pretty quick turnaround and favorable exchange rate. Not sure what it weighs with the steel fork.

Very cool!

Thanks. It’s a fun bike to mess with. Never ‘done’!
