Had this email from Robin Mather:
Hi James,
I've finally got around to sorting out my notes from your visit last week. Sorry to have taken a few days to get this done. Attached to this e-mail should be :
A drawing of the proposed design for the new frame.
The photo of your Serotta overlayed with a few dimensions that I used along with the Cyclefit data to establish your existing riding position.
A spec sheet.
Hopefully everything makes sense but feel free to point out anything I've screwed up or overlooked!
TT angle : I know we talked about the angle of the top tube but I didn't make a note of the conclusion we reached. I think you said you wanted a slightly compact frame so I've drawn it out at 7' to horizontal. This will put it parallel to a -10' Thomson stem. It's easy enough to tweak the drawing so let me know if you would prefer it somewhere else.
The Easton fork is a little shorter than your current fork. This, combined with the slightly slacker head angle result in a longer head tube. The bar position is the same as on your Serotta and I have included 15mm spacers under the stem.
Changing the seat angle from 73.5' to 73' moves the seatpost clamp backwards by about 7-8mm. The seat tube angle could go back to about 72' (depending on the exact combination of saddle and post) and still allow you to maintain saddle position.
Let me know what you think.
All the best.
Rob.

I was posting about you online just last night. [SIZE=2][SIZE=2][COLOR=#0000ff]https://www.lfgss.com/thread1790-8.html[/SIZE][/COLOR][/SIZE]
[SIZE=2]Re the top tube, am fairly ambivalent, its really about performance more than anything else, I prefer functional aesthetics to looks for the sake of it. So really a case of what will work best
Seat tube angle again boils down to performance and fit more than anything else.
I do tend to put a lot of power into my cranks so stiff bb area will be important. (having broken carbon footbeds i am aware of this)
Also I tend to stay seated, only getting up out of the saddle when pushed to do so.
Re headset spacers, what would you suggest? I am happy to go with your recommendation, so more, less ....?
How is your bike coming along, can I have a look at the designs? Am interested in how similar/different they are likely to be.
Cheers
James
i tried to upload the spec and pictures he sent but that failed
