Mid to late 1990's cycletourist range, basic chromoly steel, Sachs hubs with cheap Rigida rims (probably) and I think Shimano transmission. I think there was a 500 and a 700, might have been a 300 as well. Over here should be very cheap in jumble sales, D4 trocathlon or Le Bon Coin but probably more expensive in UK. The basic models had downtube levers, the upper range models were among the first really cheap roadies to be equipped with STI.
