Gibbon, how did you wangle the factory visit, have you got somebody on the inside?
As for the debate it all got a bit handbags and brollys over the prophet and 5!
They are expensive, granted. But you are paying for a frame that starts off as sheet aluminium, cut, bent, folded, welded, heat treated etc etc. Its not a piece of junk mass produced in a factory in Taiwan like some of the others which have a tiny ‘Made in Taiwan’ sticker hidden away underneath. Some of the components supplied on the 5 can be a bit iffy. Mine is a 5 Pro 2005, and the headset was u/s within a few months. The Hope hubs were crap (not Oranges fault really though). It wasn’t all XT but all the manufacturers cut corners on items that aren’t noticed. If you have components already then consider building it up. The only reason I bought the complete bike was I had the money to do so at the time. I wouldn’t dismiss building one as I enjoy building bikes up.
At the end of the day, if you end up with a 5, however you get it bought or home built, I don’t think you will regret it.
