Which Commuting frame for 350?

really? have you actually used the search on this site? I have. You get pages and pages of classified adds and not much else.

The most time I spend on a bike is the hour and a half a day spent commuting, seems reasonable to me to want to have a nice bike for that time spent. bikes are to be ridden after all.

Yes. Really.

I have used the search and it works pretty well, if you've got the first idea how to use any search such as google.

I think you'll find the tone of my post was pretty mild, and it's content was designed to help you.
If we all started a thread called 'what's the best fixie frame/racing frame/commuting frame' then the place would implode in about one hour.

You started just such a thread, but instead of flaming you like many others would have done I tried to help.

So here's your advice.

Get a fucking unipack.
