Team GB's bid to win gold in the skeleton at a third Winter Olympics is due to begin on Thursday amid a cloud of suspicion, accusation and innuendo in Pyeongchang.
Great Britain have defended their new skeleton suits as American rival Katie Uhlaender claims athletes and coaches are questioning the legality of the kit.
"People can speculate as much as they like", he said.
"They can point all they like but for us we just want to concentrate on ourselves".
Dom Parsons, who placed 12th when the most recent World Cup series concluded last month, has topped the men's time-sheets, while Laura Deas and defending champion Lizzy Yarnold, who were seventh and ninth at the World Cup, have done likewise among the women. We're innovators, we do everything we can to be as fast as we can be.
"A lot of athletes and coaches have questioned about whether the suits are legal", Uhlaender said.
"The rules state that everyone is supposed to have access to the same equipment as far as helmets and speed suits go and not have any aerodynamic attachments on the helmet or suit".
Rivals have questioned the legality of the team's cutting-edge suits after even unfancied British riders posted field-leading times during their practice runs this week.
Team USA questioned the timing of the Guardian article, apparently suggesting mind games were at play. One rival insisted that the British team have previously won gold by using illegal equipment, while the USA team said that the row was a "strategic move" by Britain to distract other teams.
"Athletes from various nations are talking about the British suits instead of focusing on the upcoming races. It's about who can throw down despite distractions, and we'll see who comes out on top over these next few days". All the equipment we use is checked and signed off by the International Bobsleigh and Skeleton Federation and the materials control, so they're fine with everything we do.
