I bet they were middle age poseurs with too much disposable income. More likely to be secret followers of Atkins but will eat vegetarian sushi in public

The four day tour I just did was heavily populated by guys (my age) on C50s, Kuotas, Serottas, Madones, CR1s rolling on Cosmics, Zipps and the fancy new red and carbon hubbed Ksyriums. I passed quite a lot of them on my 4 year old GT with Ultegra and A-Class wheelset
