ONCE Giant-TCR (1999)
Ridden by: Laurent Jalabert
Compact geometry for the first time. The Giant TCR, as ridden by the ONCE team during the late 1990s, was the first mass produced frame with a sloping top tube. The design, by British innovator Mike Burrows, involved a smaller, more compact frame than had gone before. Not only was it stiffer, lighter and used less material, but it could also be made to fit more people in fewer factory sizes.
Another British frame maker, David Lloyd, had introduced a frame with a sloping top tube even earlier, the ‘Concept 90′, which he produced from 1990 onwards. However this was made of steel, to the TCRs aluminium.
Laurent Jalabert was one of a number of top pros to ride the TCR and also use the frame in conjunction with smaller 650c wheels over the standard 700c diameter. This was popular on stages that finished with a climb, with some pros convinced that bikes with slightly smaller wheels were faster. The idea didn’t catch on, but in certain circumstances it may have had advantages.
