American Ashton Lambie broke a new barrier in cycling speed, crushing the world 4km record with a time of 3:59.930 in Aguascalientes, Mexico aboard dual Super-9 Track Tubular AUS discs. Cycling commentators immediately labeled him the Roger Bannister of cycling.

Ashton was the first rider ever to ride the 4000-meter pursuit distance in less than 4 minutes. The live record attempt was broadcast before thousands live on @ZippSpeed Instagram, with a happily exhausted Ashton having to be removed from the bike after he finished. His legs had locked up from the effort. This record attempt was the first time Ashton rode Zipp on the track.

His set up and performance were amazing:

  • 64x15, or 115 inch, gearing
  • 115rpm cadence
  • 14.6 seconds avervage lap time
  • 38mph, 62kph, average speed

For Zipp, the record was the reward for years of engineering, manufacturing, and marketing efforts alike. Ashton’s relationship with Zipp is a new model for working with athletes in the era of gravel racing and athlete ambassadors. 

Ashton has ridden Zipp on gravel for two years, including a recent victory on the new 101 XPLR wheelset. Zipp worked with frame maker Argon18 to supply the frame for his world record attempt. Zipp and Argon18 originally designed the frame-disc combo in collaboration with Cycling Australia. 

Zipp Advanced Design David Morse provided technical support around tire pressure and tire choice for the attempt. 

Ashton’s Super-9 Track Tubular Disc AUS, handmade at our factory in Indianapolis, USA, optimizes supreme aerodynamics, power transfer, stiffness, lightweight, and durability.
