it's used by F.1 drivers, such as Jean Alesi (former Ferrari
driver), touring car drivers, such as Nicola Larini and Alessandro
Nannini, and Miky Biasion, rally world champion in 1988. It's
used by many cyclists - the first one was Francesco Moser, who
beat the world hour record in 1984 (he was the first man to break
the 50 Kms barrier, and the previous record had been unchallenged
for 12 years).
