Team Type 1 went on the attack in Thursday's fourth stage of the Jayco Herald Sun Tour, but it was Panasonic's Chris Jongeward who won what was billed as the week-long race's most decisive stage. After the mountain top stage finish, CSC - Saxo Bank's Stuart O'Grady gave up his leader's jersey to teammate Lars Bak.

Team Type 1 Sport Director Ed Beamon said he was disappointed that the racing was not more aggressive on the slopes of the finishing climb to Australia's popular ski resort, Mount Buller.

"There was almost no action given the potential," he said. "We're pretty frustrated right now. (Matt Wilson and Glen Chadwick) had really good stuff today but the race was very conservative and we needed it to be aggressive."

Chadwick attacked with six miles to go in the 71-mile (115 km) race, but double stage winner Matthew Goss (CSC-Saxo Bank) was able to keep the New Zealand Olympian from gaining more than 20 seconds and he was eventually reeled in with less than two miles to go.

Wilson, the race's defending champion, counter-attacked as Chadwick was caught and the lead group detonated. Bak who had been helping O'Grady, still had fresh legs and was able to follow the move.

In the end, Jongewaard proved to be the sole survivor of a nine-man breakaway that went off early in the race. The Australian finished 45 seconds ahead of Christopher Froome (Barloworld), while Bak finished third to move into the overall lead. O'Grady is now in second place, four seconds behind.

Thirteen riders are within a minute of the lead, with Chadwick 37 seconds back (seventh place) and Wilson at 43 seconds (11th place).

"The guys did a great job but we really missed having Chris Jones or Moises Aldape (at this race)," Beamon said. "Not having that third GC rider hurt us today, but I think we still gave it a pretty good go."

Chadwick and Wilson remain within striking distance of the podium with only a time trial Friday and criterium on Saturday still to come.

The out-and-back, rolling time trial through the TarraWarra Estate Winery in the Yarra Valley will no doubt juggle the overall standings. Only conventional ride bikes may be ridden in the 10-mile (16 km) race against the clock.

Wilson needs only to finish the race to win Team Type 1's the mountain classification title.
