First of all I would like to say that your road bike build is smoking! Love the blacked out look of it all!
As for finding a Jabber, well, it seems that the majority of the folks that have them, love them and don't seem to part with them.
This I can certainly see. I've trawled the classifieds on all the sites known to me and even had a look on a few international eBay sites but to no avail...
I'm sort of trying to go back the other way myself. I have been on an MTB for the past 3 years now after bad decisions on my part which ended up leaving me with no road bike. Its a long story but in short...
This sounds remarkably similar to my own situation, having ended up with a hallway full of road bikes in various states of undress, I'm without a MTB. Perhaps we could come to some sort of arrangement, maybe a swap!!
I'm on a Niner SIR 9 and too happy with it and will not leave steel to go carbon, despite me liking my bikes real light. Current weight is 8556gms. But I hear that Niner is sold at exhorbitant prices in the UK, so maybe On-One is still your best bet.
You're right about the Niner UK prices. They are on my radar but at current retail are just way out of my price range. Lovely looking frames though!
As for the On-One, it is a strong contender but I don't know what it is, it just doesn't excite me. Maybe it's the exclusivity factor, being as there are quite a few of them around here... Maybe I'm just too much of a snob!? Who knows. Same go's for the Surly too.
STEEL IS REAL!
