I guess my standards are a little high. I am used to docs that conform to established ISO standards for technical documentation. Yes, at the top of the doc, there is a small 8 point font that says "Dec-11 cab dr ds". If that's a reasonable data field for a tech document, then I retract my criticism. However, I think Brompton could do better by following Shimano's example like the attached.
I realized today that Bromptons technical documentation page hasn't been updated since November 12, 2012. I guess that should have been my first clue that the document wasn't relevant to my bike.
