Thnaks for the replies! I´m looking at the assembly but it seemes like there will be hard to remove enough and keep the vital parts...

OT: Passed by the central station in Stockholm today and glanced at the bike parking lot, one bike caught my eye and it was a Miyata 1000, from a bit of googling probably from the 90´s, in great shape but clearly abonded. No air in the tires and just deep rust where there used to be a chain. But the frame and the rest was in good shape and it´s parked underneath a bridge so I dont think it has been covered i snow...

Had a talk to my LBS and former neighbour and got the advice to space the frame to 132,5 to accept both road and mtb hubs. Sounds fair, spaced my old frame frome 126 to 135 using a threaded rod but with this frame I´ll let him do the work to make sure the droppouts alligne right.

Bump! New pictures in the first post!

New pictures first post!

Very nice, definitely not a US model, and is a bit more pragmatic, in some ways.
Less chrome to worry about pitting.
More horizontal dropouts for more flexibility in components
Infinity tubing, perhaps due to it's size.

I'm wondering if some of the choices were to keep the costs down. The modern decals seem to support some of the last productions; perhaps the differences from the US models reflected their market experience.

Very interesting decal treatment of Cen Turion on the seat tube.

I think that will build into an extremely capable tourer, worthy of some good components. You really got a good deal, as current frames with those features (Soma Saga, Surly LHT, etc) cost a lot more and aren't that much better, if at all.

I'd put a solid road group, probably with bar ends on it, for commuting. For touring, though, I'd find a 3x7 RSX STI group and bolt it right on, then find a decent pair of polished cantilever brakes. For a single speed, just build it tough, I guess.

Rock and roll it.

Thanks for all replies! this winter I have been riding the bike singlespeed with 32mm studded tires and mavic a319 rims, not the quickest setup but i love the bike!

I traded a set of tyres for a shimano rx100 group and will be converting to 1x7 (or 1x8, can't remember). This is the bike in it´s current state:

The OP is in Europe. I wouldn't be surprised if this is a post WSI, Merida built Centurion.
