Hi there! The story is simple: friend of my friend of my friend bought a fixed-gear bike, separately the frame, the wheels, some special kind of pedals, and I've heard that he can ride up to 60 kmh. Now, I need some help to re-create his story =) I plan to travel a lot this summer, many hundreds of kilometres around the Europe, so I want to choice a solid bike, with low maintenance problems and high speed.

Is that really possible to get a hand on a fixed-gear bike, capable cycling up to of 60 kmh on a good straight road? I'm lighweight person, and I'm strong, and probably 30 kmh would make me more then happy as 60 kmh sounds kinda unrealistic =)

What kind of frame should I look for? Is weight really that important for the speed? Or I should invest more into the wheels? And what chain length is optimal for my needs?

There is dozzilion of information on the internet, but somehow I feel it is better to start my research from a topic like this, as I can't tell where is marketing info, and where is not.

I don't mind investing good amount of money into the bike, I just want to make sure that I'll buy essential upgrade, but not some fancy stuff.

Maybe there are some good full-sets I should consider looking into, or building bike by parts is more practical and cheaper?

Thanks!
