D.A.M.P. Butterbean frame originally built for bicycle polo from 4130 chromoly, though with geometry based on the On-One Pompino and has later had cable routing and a derailleur tab added at Oak Cycles. Clearance for big tyres, 47mm should be fine.
Top tube c-c: 58cm (effective around 60cm I'd guess).
Seat tube c-c: 52cm.
Seat tube c-t: 59cm.
Head tube: 18cm.
Since acquiring the frame it has been resprayed at Armourtex in chestnut brown at a cost of £60, then had the bottom bracket faced for £15. The frame has not been ridden since the respray.
The bad:
a few small dents on the seat tube from polo mallets, nothing structural.
I was having issues getting a mountain bike hollowtech bottom bracket to tighten up to torque. I think this is due to a combination of shallow threading, the fact the threads don't start at the edge of the shell and the 5mm spacers required on the drive side of a hollowtech mountain bike bottom bracket mean there are not many threads to catch. Without the spacer it tightens up fine, I've also had a square taper bottom bracket tighten up fine. I don't think you'll have any problems with a road hollowtech or square taper bottom bracket (the previous owner didn't anyway). Getting the threads chased would probably be a good idea too. As you can see in the photo there is no cross-threading or stripping of the threading in the bottom bracket cup.
I measured the seatpost required as 29.4mm with vernier calipers, and have since bought a shim for a 27.2mm seatpost for this size however I believe it could do with a size up.
Note that the brake studs on the seat stays are reversed. This means that cantilever brakes cannot be used.
Includes a 31.8mm seatclamp and Hope headset (though no starnut or top cap).

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
Tips:
Create headers by underlining text with ==== or ----
To *italicise* text put one asterisk each side of the word
To **bold** text put two asterisks each side of the word
Embed images by entering: ![](https://www.google.co.uk/images/srpr/logo4w.png) That's the hard one: exclamation, square brackets and then the URL to the image in brackets.
* Create lists by starting lines with asterisks
1. Create numbered lists by starting lines with a number and a dot
