14-time T.T. winner Dave Molyneux will have Patrick Farrance as his passenger for T.T. 2010.
Farrance has finished on the podium before when partnering Tim Reeves to 3rd place in 2008 - a year earlier the pair won the World Sidecar Championship together.
Farrance has also teamed up with Andy Laidlow and Roy Tansley around the Mountain Course, since making his T.T. debut in 2002.
It had been thought Gary Partridge would be Molyneux's passenger as the Manxman goes out to make history at the T.T..
Moly's machine will be powered by Kawasaki - a victory at this year's races will see him become the first competitor to win with all four major Japanese manufacturers.
