Hello,

I've done a bit of reading but have probably over thought a few things and am now interested in getting some feedback on my thoughts.

Over the past few weeks i've put over 60 miles on a pos Mongoose XR-75 mtb in 12-15 mile increments at 12-15 mph. My goals are to work up to riding ~40 mile increments at decent speeds.

I am new to road cycling and am basically looking for a means of getting back in shape as i've let myself go as of late. Right now this is more of an interest than anything else and I would like to stick to this for a few months before diving in head first as it's real easy to get excited about something and not maintain consistent effort.

First question:
I following the Fit Calculator's instructions and got the results below. I am assuming I need a 56mm bike and a 58mm will also work? is this correct.
Second question:
From what i understand on a budget bike i should make sure to get a decent frame, wheels and crank? I would hate to go crazy and buy an expensive bike and not continue to ride, basically wasting money. Instead, i would like to buy a budget bike and see how it goes over the next few months.

I've read a bit and understand the Kilo is the entry bike of choice but id "prefer" to spend a lot less on a bike for now. As if this is something that becomes more of a lifestyle for me i would like to get a really nice quality bike and i understand you get what you pay.

I've noticed bikesdirect has a few bikes on Black Friday special and even has the Gravity Swift for $229 shipped and a few other modes in the ~$300 shipped price range.

Would this (gravity swift) be a decent entry level bike for ~20-40 mile trips for a few months?
Also does anyone know if these bikes can be seen at local bike shops or are they bikesdirect exclusive?

Only reason i havent visited a local shop so far is because i would like to be a little more educated before going as to know what i want.

Any advice and recommendations will be welcomed. Thanks in advance.
