David Millar’s Slipstream team has a new sponsor ? the satellite navigation system manufacture Garmin ? and will unveil a new jersey at the Tour de France.

The team will become Garmin-Chipotle, with the Mexican-style healthy fast-food restaurant chain continuing its co-sponsorship.

Argyle lovers need not fear, the new jersey will retain the distinctive checkered design.

Slipstream is the name of the management company owned by Doug Ellis and Jonathan Vaughters and the team has continued with that name with Chipotle, H30 and Felt Bicycles as secondary backers.

Garmin was one of those secondary sponsors but has stepped up to sponsor the team until the end of 2010.

Slipstream is the third team in as many weeks to get a new sponsor.

Earlier in the month Saxo Bank signed up to co-sponsor Bjarne Riis’ CSC team. They are now known as CSC-Saxo, with Saxo taking the title sponsorship when CSC withdraws at the end of the season.

And last week Mark Cavendish’s High Road team announced it would become Team Columbia at the Tour de France.
