Simon joined BikeRadar in 2020, but has been riding bikes all his life, and racing road and time trial bikes for more than a decade. He’s also developed a keen interest in gravel bikes and riding off-road in recent years.
As well as covering news and trending topics in road and gravel cycling, Simon writes in-depth reviews and features on power meters, smart trainers, aero tech, and nerdy topics such as chain lubricants, tyres and pro-bike tech from races such as the Tour de France.
He has a keen interest in any tech that can help him (or you) ride faster and is obsessed with the tiniest details.
