Kästle is an Austrian firm,producing ski-equipment since 1924.In the late eighties Italian bicycle confectioner Atala became the owner of the Kästle brand,so low-and mid-priced bikes arrived to the Austrian and Italian market(distributed by Benetton Sportsystem) with a name known from ski-sport.
This bike is a "stock old" one,it has spent a dozen years in its box till last
Xmas. The frame was made in Taiwan,the bike was assembled in Italy.
DiaCompe V-brakes,Joytech hubs and Kalloy seatpost are also from the Far-East. Crankset( Biopace),chain(HG),rear sprockets and both derailleurs
(Acera-X) are Shimano. Alu-rims are Italian FIR products,the tires are Czech Rubenas,saddle(leather edition) and the handle-cuffs are from Ritchey(also made in Taiwan).
Although it's a full rigid steel bike, it handles and rides beautifully: it's a joyfull cycle...

Nice looking bike, love the colour and the matching tyres.
Not a bike you see to often, were they very popular in continental europe?

No,really not,it's a kind of exote.
They were sold only in few regions of Austria and Italy.
Selling bikes under the name of a ski brand did not prove a financial success despite every effort of Benetton SportSystem.

Sounds a bit like Kawasaki, I bought my KMB450 when they were selling them off after deciding that mountain bikes weren't really where they wanted to be
I'm guessing it was made in the mid 90's?

Yes,correct
The year of make is 1997.
My elder daughter uses another Kästle-cycle: Tange-tubing,Rigida alu-rims,full Shimano STX SpecEdition trek bike(made approx.'95-'96) -that's also a kind of retro-...

I don´t quite get it, why this should be NOS out of the box. The Biopace chainrings were long gone, when V-Brakes came up (and IIRR the Acera gruppo). It seems to me like a mixture of late eighties/mid nineties components.

But if it fits you, have fun.

Hmm,my argument is that I bought this cycle in absolute unridden state from it's original(but heavily shattered)box,so I think probably it's really a NOS one -this fact is of course without any real importance. But you're right,the parts are really not homogenously period-correct. I can not figure out when and how was it equipped with these bits...
Luckily enough,there's no problem w the fun-factor: I like this bike, it rides lively and... it's blue
(not a very pleasant shade of the colour,but an eyecatcher)

some further pimp...

nice. is it steel framed?

Shape of the down tube is very similar to Dawes frames in the late 90s. Probably came out of the same factory.

I have had my Kastle Trekking Pro for a decade now, it is very well built and solid. One of my favorites for city rides and it's FAST !!

I cannot date it exactly, but my guess it is a 1990 Model.

It has a Colombus Cromoly Frame with full first issue Shimano Deore DX. Also Ritchey Headset, stem and handlebar.

Rims are Italian FIRs which are also good quality.

Yes,it's a steel-framed bike.
Numerous cycle-producents ordered/order complete framesets from Taiwanese makers,that's how bikes of different brands could became "relatives".
Or simply in the last years of ninetees that kind of design was a fashionable solution...

In as far as it is round?

Dawes were made in the UK 'til 2000, then Czechoslovakia, then from 2005, China and Taiwan too
