First fixed bike build thread - Help build my first singlespeed or fixed bike

Which forum do I have to post this in for it not to be moved?

Yes i'm sure the question has been posted before but theres more to it than that. I'm not asking how to convert an old frame but what the best option would be for me.

Hi Guys. I've recently got into single speed bikes and have a mongoose maurice to get me through the winter.

Next year i'm hoping to build up a nicer and more expensive single speed. I'm not converting something I already have, so will be purchasing new parts. Just looking to see what the options are really and the pro's and cons. This will be my main bike for training. Hills and everything.

I think I have the following three options;

1) Track frame with single speed flip hub.
Pros: Easy to get correct chain tension
Cons: Pay premium for track frame. Lack of expensive single speed clincher wheels

2) Old steel frame with horizontal drops
Pros: Loads to choose from and pretty cheap.
Cons: Lack of new wheels with 126mm spacing. Difficult to get correct gear and chain tension.May need 1 tooth bigger/smaller to achieve tension.

3) Old steel frame with horizontal drops cold set to accept modern 130 spaced wheels
Pros: Can purchas brand new wheels. Loads of frames to choose from
Cons: Difficult to get correct gear and chain tension.May need 1 tooth bigger/smaller to achieve tension.

==========================
I'm thinking of going with option 3 because i can run nice wheels and have loads to choose from. Also, I will be able to get a nice frame and not have to pay a premium. i.e. cinellig vigoreli frame costs about £500 when I could get somthing else just as nice for about £250.

I understand I can also cold set a frame to take 120mm fixed/single speed wheels but this doesn't appeal.

This will be the fist single speed i've done. Am I on the right lines? Is option 3 a good one?

Thanks in advance.
