On One Pompino owners...

On-one are making a frame a bit like this called the Machinato, here is a picture of some prototypes from their blog (the red and blue-purple frames):

You can see it more side-on on this photo from Dalby Forest, look at the large size and compare Machinato with Pompetamine and Pompino below.

A cheap steel On-one frame with track sensibilities that takes normal caliper brakes is very tempting; decals and colours not to my taste though.

I think the red one looks pretty decent. Not sure how much they have slope on the top tube (or do they have at all, hard to tell from the pictures), as that might be an issue with some ppl.
