Following Matej Mohoric's victory in Saturday's Milan-San Remo race with an assisted dropper seatpost, the UCI issued a statement clarifying its regulations regarding the use of the equipment.

The super tuck position for Slovenian riders was banned more than a year ago.

In a short statement Sunday morning, the UCI said that the use of dropper seatposts was approved for 2014. However, the saddle setback rule applies whether the seatpost is in the dropped or normal position.

"The UCI Equipment Committee approved the use of dropper seatposts in road cycling competitions in 2014.

"Their use is subject to the minimum 5 cm setback rule of UCI Regulation 1.3.013." In other words, if the dropper seat post is set to the highest or lowest setting, the setback of the saddle must fully comply with Article 1.3.013.

Article 1.3.013 states that "the peak (front) of the saddle must be a minimum of 5 cm relative to the vertical plane reading through the bottom bracket spindle," a rule that in theory limits how far a rider can lower the seat post during a race.

Mohoric effectively used his Fox Transfer SL Performance Elite seatpost while descending Poggio on Saturday afternoon to open up a gap on the leading contenders behind him, including Taddei Pogachar, Wout Van Art, and Mathieu Van Der Pol.

The Slovenian said after the race that he and his team had been working on this particular plan all winter. He also said that using a dropper seatpost would give him greater maneuverability and a lower center of gravity, making it a safer option during training.

"We chose the MTB model because, according to UCI regulations, we had to use a commercially available dropper," Mohoric explained.

"We tested a 12-cm dropper, but that didn't pedal efficiently, so we opted for a 6-cm one.

"We changed the bar grips and lowered and raised them many times on the descent of the poggio. The idea of using a dropper post has long been dismissed, but now the technology has advanced and it's no heavier than a regular seatpost.

"Maybe next year, all bikes will have dropper posts. It's safer in traffic, it's better for training. It gives you better braking. I think it will be a big advantage in the races."
