Fui procurar um pouco para ter a certeza que não era a minha imaginação a lembrar-se que tinha lido há tempos sobre isso.

The 6.8kg weight limit has been questioned, debated, and reconsidered throughout the past thirteen years, but it now seems to be outdated to the point of absurdity. At the Tour de France we noticed many team mechanics adding weight to rider’s bikes in order to meet the minimum weight limit. They would put a couple hundred grams of fishing weights in the seatposts, handlebars, or chainstays to boost the weight up to 6.8kg. And while the bikes were certainly top-end, they weren’t using exotic materials nor trying to be a weightweenies bike.
We asked UCI Technical Collaborator Johan Kucaba if the UCI still believes that a bike lighter than 6.8kg poses a significant safety risk to riders. He explained:
“The rule 1.3.019 has been introduced and has been created as many other rules of the UCI Technical Regulation by an ergonomist expert in cycling. This specialist, with the advice of other experts, has defined that 6,8Kg is the minimum weight acceptable for a bicycle, for an essential reason that is the manoeuvrability of the bicycle. Of course, technical risks related to composites materials have also been considered, but the primary reason of this rule is the manoeuvrability. We therefore believe that bicycles of 5 Kg (for example) pose significant risks of manoeuvrability.”
