Help me to understand some part choices.
 

Hi, I'm working through a LBS and I'm about to have a bicycle custom built.

I want to use an internal hub. I'm thinking a SA 5 speed hub. I want simple bolt on wheels and a simple steel frame. I need strong wheels - I'm 250ish. I want 28 tires. The purpose of this bike will be frequent 40 mile rides - and when summer approaches a 400-500 mile tour. I would like treking bars.

I want a freewheel, I've tried fixed and enjoy it, this bike will be for distance. Basically, I want a simple bullet proof bike. I'm wanting to run a 44 single in the front, btw - just the 5 speed in the back. On my single speed I'm most comfortable with a 46 front and a 20 back (lots of hills here). So I would like a range about 2 below this and 2 above this if I'm making sense.

Thanks for thoughts!

Kilo WT5?

ETA: Sorry, you already have a frame picked out? Or... What is your question about?

I'm a big guy, too. I'm not sure if you are in it for the cool project or you just need a good bike for the job.

If you are in it for a good bike for the job, have you considered an off-the-shelf road bike? They will hold your weight just fine. This way you can try before you buy. With custom builds from the ground up, you never get to ride it till you've bought and built it. Then you are committed. My last road bike was a Teshner built from the frame up. It was OK...then I rode a Specialized Tarmac and was like, "Holy sh*t this is nice..."

If you buy off the shelf, just avoid the ultra-light wheels. But, if you got a bike with such wheels, you can easily find someone to trade a beefier set for them. A road bike will definitely be easier to ride longer miles on than some other types of bikes.
