Can I ask where you get your tubing from? What thickness('s) do you go for?

Yeah, sure. I used Aerocom metals - http://aerocommetals.co.uk/pacesetting-alloys/

 

They were easily the lowest cost compared to other suppliers of T45.

 

In terms of thickness, I over-did the downtube (38.1 x 1.6) to ensure my tube bender could handle it, but looking back, I think I could of gone down to 1.2 with no issue.

 

The top tube/chainstays were 1.2 (22.2 dia) and bent with no hassle.

Looking real good. Love the top tubes following the whole frame down to the dropouts. What design did you go for around the bb yoke? 

I went for a pretty simple 3 piece. Worked out quite nicely and seems quite stiff at the moment.

So clean looking. What's the weight, geometry, and cost?

Heavy, just over 3kg.

 

1065, 73 deg, +67, 377 stays (at the moment, will open up once the chains sorted itself).

 

A lot. Mostly spent on tooling up for the job, but the T45 came to just under £300 to start with.

 

The old mark up was between £120-180 if I remember rightly. Not great for 2-3 days work plus the design stages when your a self employed fabricator unfortunately.
