Ashton Lambie broke the 4K track world record with an average speed over 60kph, his 3:59:93 pace is the first time a solo rider broke the 4:00 record. Earlier this year Filippo Ganna set the record at 4:01:934. UCI officials confirmed his effort on site in Aguascalientes, Mexico. Lambie rode an exotic, purpose-built Argon 18 that blends the top watt-saving, wind-shedding tech available.
