In 2005 Leclercq joined Dragonforce as a replacement to Adrian Lambert on the Sonic Firestorm tour. He released 7 albums with the band. He later parted with the band due to wanting to pursue other types of music on his own. Guitarist Herman Li once said," I didn't want to get Fred because he is such a phenomenal guitarist."[citation needed]
On 16 September 2019, Kreator announced that Leclercq would replace Christian Giesler on Bass after having spent 25 years with the band.[5]
In 2020, Leclercq formed the musical project Amahiru with Japanese guitarist Saki. Saki performs lead guitar, while Leclercq plays lead, rhythm and bass guitar. The two first met in 2015 when Saki's band, Mary's Blood, opened for DragonForce in Hong Kong. Amahiru's self-titled debut album was released on 27 November 2020, and features British vocalist Archie Wilson, Dutch keyboardist Coen Janssen, and American drummer Mike Heller. It also features shakuhachi player Kifu Mitsuhashi, and guest performances by Elize Ryd and Sean Reinert.[6]

Leclercq uses ESP bass guitars and has a signature model, the LTD FL-600, with five other bassists (the others being Gabe Crisp, Frank Bello, Pancho Tomaselli, Tom Araya and Henkka Seppälä). Whilst performing in Sabaton, he used an ESP horizon electric guitar. For amplification, he uses Peavey Tour 700 bass amps and 8x10 bass cabinets, along with a Samson UHF Wireless System.[7]
