UCI announces major regulatory overhaul: Front jersey pockets banned and bike computer sizes limited

The UCI Management Committee has signed off on a series of significant regulatory reforms targeting equipment, rider safety, and the yellow card system. These updates will phase in over the coming seasons, with the earliest changes taking effect next month.

In an immediate move to crack down on aerodynamic loopholes, the UCI will completely prohibit front-mounted jersey pockets starting next month. The governing body noted that teams have been using internal front pockets stuffed with nutrition products purely to alter the rider's frontal profile and gain an aerodynamic advantage.

The UCI argued that this practice compromises sporting fairness and introduces safety risks by increasing race speeds. "The nutritional products were generally not consumed because they were extremely difficult, or even impossible in race conditions, to access. These pockets result in significant alterations to the riders’ body shape," the UCI said in an official statement.

Going forward, pockets will be restricted entirely to the rear of the jersey, with one exception. "Any pocket positioned on the front of a jersey will be prohibited, with the exception of a possible pocket intended solely to hold a radio communication device."

Looking further ahead, the UCI will regulate the physical size of onboard electronics. Beginning in 2028, bike computers will be restricted to a maximum dimension of 126mm by 71mm. The UCI justified the restriction by pointing to the psychological strain and distraction caused by excessive on-screen data.

"Several studies have shown that the increasing volume of data available to riders during competition can contribute to an increased cognitive workload, a key factor in the occurrence of accidents. Limiting the size of bike computers is intended to prevent an excessive increase in the amount of data available during races, which could significantly compromise rider safety."

The UCI also announced a broader rollout for its controversial yellow card system. Following feedback from its trial in the WorldTour and ProSeries, the system will expand to Elite men's and women's Class 1 events at the start of the 2027 season.

Similar to soccer, race commissaires issue yellow cards for dangerous infractions that threaten peloton safety. The system relies on a cumulative penalty structure. Receiving two yellow cards in a single-day race or a single stage results in immediate disqualification and an automatic seven-day suspension. Cards accumulate over set periods to trigger multi-day suspensions for repeat offenders.

"This system aims to improve safety by increasing the accountability of the various individuals present in races," the UCI stated. "Although the accumulation of yellow cards can result in short-term suspensions, the objective of the system is above all to prevent potentially dangerous behaviour."

Additionally, the UCI will introduce standardized hazard pictograms across the international calendar. "These new safety pictograms signalling dangerous points (e.g. road narrowings, sharp turns, speed bumps, level crossings etc.) will start to be adopted by race organisers for next season and will provide riders with uniform safety signage at events across the international calendar."
