You may have seen this frame before on the site. It's been owned by bratfass, sithlord, ringo and bought by me in April 2012, since when I've been collecting parts for it.

All I know about Biria is that it was a German company started by a man of Iranian descent. It was bought by an American group in 2005 and I believe it's now based in the USA. Biria now makes folding and city bikes mainly.

I think the frame is probably a Taiwanese job. It would be great if someone could throw some more light on Biria and their bike range from this era. I would be particularly interested in knowing what the frame tubing is. Even this frame has been made of everything from Tange Infinity triple butted to Ultimate Superlight according to some posts. I have taken the liberty of putting an Ultimate Ultralight decal on it, until somebody tells me otherwise. I’m reasonably sure that its successor, the MX 700 was made of Tange Ultimate Ultralight. Everyone seems to agree it's some flavour of Tange though. You might wonder why I don’t just weigh it to see if I can get some clues, but at some point the frame has been filled to the brim with waxoyl, so I don’t think that’s going to tell me much.

You could describe the paint as a bit of a Marmite thing in more ways than one. Personally I like it, reminds me of an old Wolseley car interior, just the thing for riding down to the pub smoking a pipe and wearing a cheesecutter cap (and very little else!).

Bratfass has an excerpt from a magazine showing one BITD with Marzocchi XC500 forks, Shimano XT groupset and gold anodized Mavic rims. I thought it would look good with Suntour xc pro in champagne finish where possible, and Mavic 217 sunsets, and I think it does.
And discuss.........

John

That is gorgeous! What a great bike... Only slight point would be the stem - but i guess you need the rise.

Made my day seeing that though... If you ever want to sell, that would be a great bike for 'er indoors!

At my age I'm a martyr to lower back pain, I need all the rise I can get!

John the XC Pro is stunning with that, and the Sunsets match perfectly.

Loving your build, I always did like that frame.

Doing a XC Pro build myself at the moment, great fun!.

:lol:

That is very nice, and in that tubeset it should ride well too.
