Tiernan-Locke wrote his name into the history books at the weekend as he became the first home rider to win the Tour of Britain in 19 years, finishing 18 seconds clear of his nearest rival Nathan Hass.
This continued the 27-year-old's fine 2012 that has also seen him win at the Tour of the Mediterranean and the Tour de Haut Var, as well as returning from a broken collarbone to win the Tour Alsace.
And it could yet get even better as Tiernan-Locke will now travel to Maastricht as part of Great Britain's nine-strong team for the World Championships.
He will join Cavendish as the Manx Missile attempts to defend his crown, and the reigning champion believes his chances of doing so are improved with Tiernan-Locke by his side.
"We are really looking forward to having him [Tiernan-Locke] in the national team," said Cavendish.
"He is an incredible talent and his Tour of Britain proved that and I really think he will be a big asset to the team.
"I think he is moving up in the ranks to a pro-Tour team next year and I think he will do quite well there."
