Ineos Grenadiers' Performance Engineer Dan Bigham has explained why his mechanics have duct taped the race transponder to the rear of the forks on their Pinarello Dogma F race bikes. 

Earlier this week, Cyclingnews spotted the transponder's unusual position on the bike of Egan Bernal, speculating that it was likely the latest finding in the team's pursuit of marginal gains.
