Weren't Barum a Czech make?

Yes, according to WP.

I still have a pair in the shed.
Rubber casing is still sound at 25 years old and they hold air ok. Stored on old sprint rims.

I do remember having some 27" barum clincher tyres. That would have been around 78-79. I remember puncturing on a ctc ride and the sidewalls were that stiff, the tyres didnt run flat on the tread, the walls folded so that the sidewall was in contact with the road. I never bought any more, but they would have been cheap, I was skint and everything was on a budget

Riders from the Eastern Bloc riding the Ras Tailteann here in Ireland in the 80s always came with dozens of Barums to flog on before they went back, they would tell the bosses back home they just had a lot of punctures!

I used Barums - and Kowalit - tubs BITD. The prices were at a level I could afford and the performance was OK. In fact the first time I beat the hour I was riding my training wheels (it was a very wet evening!) which were clad with Barums. There were also some Japanese tubs by Soyo that were very light (6oz?) and very competitively priced - especially when compared to the equivalent weight Clements!

Here's a couple of ads for period tubs. Revel in the prices..................

Oh yeh, I remember same in milk race and sealink international. I knew a few lads who rode them and told us the same.

The eastern block riders also used to go on walkabouts, guess it was their chance to see the outside world. If they were late in after curfew time, the initial thoughts were that they had defected and all their staff would be running around, making calls and panicking
