Viking Allrounder Serial No. 120263

I don't want to buy a OTP cheap fixie, I wanted to build a single speed from something old because I'll enjoy it and end up with something I created...

If you're saying this is just totally the wrong frame then I'll give it away and just look to buy another old bike for such a restoration...but ideally with more race geometry.

My point really is there is a lot of work and you can do it sympathetically, using the majority of the existing parts.

Even by removing all of that extra weight from the wheels, seatpost, and probably cranks, it's likely to be a heavyish frame designed for comfort.

If you want a fast feeling single speed, then I'd look for a complete proper racing bike from the late 80s or 90s.

This would be awesome: http://www.ebay.co.uk/itm/CANNONDALE-CAAD3-600-SILK-ROAD-TRIPLE-105-HEAD-SHOK-EXCELLENT-/290773577381?pt=UK_Bikes_GL&hash=item43b374aea5&_uhb=1#ht_693wt_1397

grab some full carbon forks, a 25.4 mtb stem and some easton carbon risers, then use a magic gear or chain tensioner.
