Singlespeed Randonneur build advice

Hi.I want to build a unique machine for randonneuring/long distance light touring.Right now I use my specialized awol for that purpose, but i want to build something more road specific, single speed and randonneur style bike. I also want to build it on a budget, try to find used good parts.That's where any help is appreciated. I want it to be something like this: old skinny road bike frame (old ktm or peugeot or italian frame beacuse I live in europe and that's what's available), good new wheels, spd pedals, dynamo hub, modern road bike brakes , mudguards so in general a reliable road build but I don't know anything about singlespeed parts, or which crankset is good for that kind of riding, what ratio etc.I've seen this picture somewhere, that's where I got the idea.

Interesting Prospect. You might try posting on the single speed / fixed gear forum and referencing them here. I recall reading some articles about P-B-P single speed riders which might help you.

You can find gear calculators online and plenty of information on which gear ratios to start with. I would think something in the 65 - 70 gear inches would allow you to go long distance and also keep it reasonable for hills. If you get a flip/flop hub you could run a freewheel on each side with the second one being a lower "bailout gear". I used to run a 39/16 fixed (65 gi) with an 18t freewheel (59 gi) as my bailout. Didn't do long distances but it worked well enough.

I now run a 44/17 for 70 gi with lighter wheels and it is good. I still have an 18t freewheel if needed.

velomine.com seems to be the go to place for reasonably priced SS wheelsets. They had some touring wheelsets with generator front hubs, but I don't recall any SS wheelsets with them.

Good luck.

The only difference between a FG randonneuring bike and any other randonneuring bike is rear hub and the chain-set. Budget way to go would be to get an old road bike with horizontal dropouts that's as close as possible to what you are looking for and put an old single-ring crank on there with a fixed rear and front dynamo hub. I doubt it will be easy to source an inexpensive wheelset like that so you may consider getting the parts and building it yourself. I run right around 70" most of the time, but gearing is pretty personal. You'll have to figure out what works best for you.

My single speed experience is limited to a mountain bike with slicks, but I concider it to have 2 speeds, sit and spin or stand and mash. It seems like the light tubeing low trail bikes are set up more for the sit and spin crowd. I'm not a small person, and when I get out of the saddle on my road bike, the limitations of tire and fender clearences make them selves known. Again not knowing, I wonder how a low trail bike handles differently out of the saddle?
I've got a bunch of sport touring frames in the attic, so I've thought about building a low budget version just to see.
