The enforcement of those rules will take effect starting on April 1 “after a period of adjustment for riders, teams, organizers, and commissaires.” “The UCI Management Committee also decided to reinforce the regulation concerning potentially dangerous conduct of riders, including throwing a bottle onto the road or within the peloton (which may pose a danger for following riders), and taking up dangerous positions on the bike (especially sitting on the top tube),” read a statement from the UCI. Now, the UCI says it plans to enforce a ban on the “super tuck” as part of its rules against “dangerous conduct.” Throwing water bottles into the road, another common occurrence with potential safety implications (as Geraint Thomas experienced when he crashed out of the Giro d’Italia after hitting a wayward bottle last year) will also be prohibited. Those concerns were discussed along with several others last year during meetings of the UCI Management Committee, which then drafted changes to the UCI’s safety rules.

The use of the “super tuck” has courted controversy, however, as many have questioned the safety of the method, both for the rider using it and for those around that rider. Chris Froome notably employed the technique as he soloed to victory on stage 8 of the 2016 Tour de France, and it has been used by countless other riders in major races over the past several seasons.

The tactic of hunching over the bars while putting weight on the top tube in an attempt to present a low aerodynamic profile has become increasingly popular in recent years. The UCI announced a number of updates to its rules and to its enforcement of them in a wide-ranging statement on Thursday that included several new safety provisions drafted after “a long consultation process.” Among the most notable changes to the organization’s safety protocols is a commitment to enforce a ban on the so-called “super tuck” starting on April 1.
