To clear up the 157x12 hub mentioned above, 157 is to 150 what 142 is to 135, it's just a cowled version of a normal 150mm hub. That frame was made just as boost was announced and I would now use a 148 hub and 73mm shell instead to achieve the same clearance but with greater hub/crank availability
Thanks Matt that makes sense now especially the comparison with 135/142.
My only concern with your bike is the proximity of the rear tyre to the seat tube, do you find it an issue at all? Also looks like there's more adjustment in the sliding dropouts than there is air between the tyre and seat tube... Why's that? Do you only intend to shorten the stays with a much narrower tyre (or perhaps a 650b+) in place?
Ha ha - I [i]could[/i] get mine as close as Shaggy's!
Never been an issue on mine and now running a NN in the same position. Photo was with a RR. I think it looks a little closer than it actually is. You have hit the nail on the head though - should be room for a 2.8 650+ and also aesthetically I think it would look odd with loads of dropout sticking out the back. There's still plenty of adjustment to go SS
That's 18 bikes frame looks awesome!

Remember seeing that one in the shop and liking the curved seat tube brace
Why if going custom would the customer spec such a small frame though? There is soooooooo much seatpost showing that Thomson must be right on the min insertion line
^ Yeah I thought that. Great looking frame and interesting features, but you can't drop the post down very far anyway, and there is so much leverage on the seat tube and top / seat tube brace. Conventional wisdom says that the seatpost should go down at least to the bottom of the top tube (the real tube, not the brace), and I've seen a variety of frames ultimately fail when this isn't adhered to. Granted, this is 853 so pretty strong. /armchairengineer.
If I remember rightly, the seat tube length on that frame was an aesthetic decision, the point of custom is that you can have what you want, in this case it was a small seat tube in other cases it might be a long one, as long as the customer gets what they want, I'm happy
As an example, my frame was designed around a 170mm drop reverb and getting overlap with the top tube as mentioned above, it's ended up with a seattube that's about 16" and I'm 6'1", make of that what you will

Would you ask your tailor to make you trousers 2" too long, or would you have them cut to your exact leg length?

This.
I bet if it was a 27.2 seatpost he was also going for max flex off the seatpost for a more forgiving ride.
On a side note I've had a few Ti custom frames built for me an TBH unless you're a real odd shape and size or looking for something that no production frame even comes near to you'll just be waisting money and time...
