Hi everyone. I'm new here and new to everything about bikes. Other than the bikes I rode as a kid, I know nothing else.

So I'm looking in buying a Kilo TT from bikesdirect to commute to and from school.
I've been reading a lot on the forums and I think that's the bike I'm gonna choose for sure.
Also, since its a center to center measuring, it's a little different.
I'm 5'7 and was wondering what size I should buy. I narrowed it down to 50cm and 53cm. Most likely 50cm.

Since I'm on a college student budget, can anyone recommend some cheap brakes and other accessories. that I would need for my bike? (tools, brake lines, brake handles.. just name anything i would need)
$350 for just the bike itself is already hitting my wallet HARD.

This bike is going to be my first real bike and I plan on just riding it with stock parts as long as possible until I get money to start swapping in some better parts.

And before anyone starts flaming me, I have been searching and reading the forums.

Thanks!
