There is no mention of 'mountain bikes', even though they almost existed at the time. The new Deore series is explicitly described as a 'touring' groupset. Interestingly page 33 also features the famous 'Deer Head' logo. This logo did not appear on a derailleur until after the 'touring' Shimano Deore had morphed into the 'mountain bike' Shimano Deore XT. But I am pleased to see the famous logo unarguably associated with the unglamorous activity that is 'touring'.
Shimano is famous for its depiction of cyclists in impractical attire - but the idea of cycling in white bell-bottoms (see page 37) is a new high-point!
Page 62 may mark the very first appearance of an image promoting Shimano's aerodynamic initiative. This page is possibly the first shot in what was an unprecendented media onslaught.
