Derailleurs were banned for Coureurs (the top class and main classification) in the Tour de France from 1919 to 1937. Super Tourists class were allowed them and used them too. Road racers widely started to use derailleurs in other races from about 1932 onwards. Simplex had a derailleur gear that was specifically aimed at racers and the Super Champion Osgear became very popular after its introduction in 1934 and was the only derailleur allowed in the TdF in 1937. The next year, the Italian Vittoria Margherita gear was allowed too. Road racers had used derailleurs prior to WWI in the Tour but restrictions weere imposed some years on gears even then by the organisers. One year, the organisers even tried to demand fixed wheels. The riders rebelled and the organisers relented allowing freewheels which were practically essential on the long descents. Derailleurs were only used by by a very small number of riders (be they tourists or racers ) in the early years of the 20th century despite a a lot of experimenting. In the 20s tourists began to take to the derailleur increasingly fast and racers were not far behind. Even in the first British road race held in the 20th century at Brooklands in 1933 most of the field were using gears, with a sizeable percentage using derailleurs. The Campagnolo Corsa gear and others of its ilk were ridden by very few riders. Pre-WWII it was not seen I think outside of Italy. The Super Champion Osgear worked pretty well and had a speedy change in skilled hands. Immediately post-WWII the Simplex Tour de France took over which also gave a speedy and more reliable change. It's very easy to get the wrong impression by just studying what gears were available. In practice only a small number of different gears were widely available and used. Very few chose the Campag Corsa.though it was seen a few times on sponsored riders machines in the TdF.

>> Bicycle and bicycle component manufacturers will not generally build bicycles or bicycle components which cannot be used in their intended field. And cycling is pretty sport led. You only have to see how cheap mountain bikes that will never see mud ape their serious cousins. So if the UCI ban sloping top tube frames manufacturers of road racing bikes will build their frames with horizontal top tubes whatever their merits. It would be commercial suicide to do otherwise. And there is no doubt that the ban on derailleur gears in the TdF from 1919 slowed gear development for road racers. If the UCI starts to regulate mountain bike sport as closely as it does the road sport we will definitely see a reduction in the designs available. For example if rear suspension was banned in downhill races would manufacturers continue to build downhill bikes with rear suspension? Of course the answer is no.
      If the UCI had banned pneumatic tyres for racing would that have meant that pneumatic tyres were not developed? Probably not but their development would have been radically slowed until the inevitable happened and the UCI relented.
      Cycling as a sport booms every time it becomes glamorous or cool. There is no doubt that Chris Boardman's Olympic medal in Barcelona in 1992 meant that more people outside of the sport in Britain took a look and thought it was appealing. And the same happenened in the US after Los Angeles Olympics in '84 and with Greg Lemond in the late 80s. That does not mean that they will instantly get on their bikes and start commuting by bike rather than by car. But what some will do is to buy a bike and ride it for leisure and fun perhaps on cycle paths. They will slowly become a little fitter and some will then try the odd commute. If there's other encouragement (higher petrol prices, more congestion, increasingly difficult parking, slower safer motor traffic, a few cycle routes and increasing numbers of other cyclists) may be tempted to give it a go themselves. Sticking their bike on the back of the car and then riding it is a just the first step towards greater bike use ­ only some riders will take that next step but those few are far better than none.
