"It's just a Kiwi bike," the New Zealand track cycling queen said after blitzing her opponents in the individual pursuit during qualifying heats at the world championships in Melbourne.
"I think it's more about the person riding it, actually," she told reporters.
Ulmer, 28, blitzed the 21-strong field, qualifying more than 3sec faster than second- ranked Russian Olga Slyusareva.
In a sport where wins are measured in thousandths of a second, Ulmer's time of 3min 30.604sec was one-fifth of a second faster than the time set by Dutch legend Leontien Zijlaard- Van Moorsel four years ago.
As The Press revealed two weeks ago, Christchurch bike builder Milton Bloomfield designed and constructed a high-tech carbon composite bike which showed enormous potential in initial tests.
Although Ulmer downplayed her new wheels, any lingering doubts she may have had about her radical new design must surely have disappeared in the 3½ minutes it took her to power the sleek, black machine around the 250-metre velodrome at Melbourne's Vodafone Arena.
As international media clamoured to talk to the new world record holder, Ulmer faced the inevitable questions about her steed _ and remained tight-lipped.
Also not talking was Bloomfield, who was trackside to see his machine in action. The proud designer refused any further comment on the new bike, with some "technical issues" still to be sorted.
Ulmer approached Bloomfield to design a bike because she was keen to ride Kiwi-made wheels in her bid for Olympic gold. The new carbon-fibre composite track bike was built in Bloomfield's Ferrymead factory.
Her world record was a first psychological blow to her rivals in the build-up to the Olympic Games. Adding gloss to her achievement, Ulmer created the mark while riding against Zijlaard-Van Moorsel, who lapped her in their semi-final at the 2000 Olympic Games in Sydney.
"That's cool. I've never beaten her before," an elated Ulmer said.
Ulmer was keeping her feet on the ground despite her record breaking time.
"I'm stoked but tomorrow's a totally different day. I'm well aware this is early days. I don't want to get carried away just yet," she said.
A gracious Zijlaard-Van Moorsel, 34, praised Ulmer, saying she was just relieved to have qualified for Athens by finishing inside the top 12.
The Dutchwoman missed the World Cup qualifying circuit as she juggled her road cycling commitments with preparation for track events.
"The record has stood for four years _ you have to accept that someone can break it," said Zijlaard-Van Moorsel, who has won the last three world championships titles.
"She (Ulmer) is in really good shape. I've seen her riding in training and she was looking really strong."
With the world record in the bag, Ulmer now focuses on the world title, starting this morning with a quarter-final race against eighth qualifier Emma Davies of Great Britain.
