THM — named for founders Thomas and Petra Mertin — was established in 1996 in Alt Duvenstedt, northern Germany, by an aerospace engineer looking for a niche where precision manufacturing could meet cycling. The company’s breakthrough came when its carbon crankset and fork were chosen by the Deutsche Telekom pro team — products that were, at the time, the lightest of their kind in the world. THM still operates as a compact specialist manufacturer from the same Alt Duvenstedt location, making every product in Germany. More on the brand and its approach at THM’s official website.
RA Cycles carries the complete THM lineup. The Clavicula SE is THM’s flagship full carbon crankset — the product that established the brand’s reputation and remains one of the lightest road cranksets available. The Fibula brake calipers apply the same carbon-first approach to rim braking. The Ulna handlebar, Mandibula seatpost, and Tibia stem cover the cockpit and contact points, and the collection includes THM’s full range of bottom bracket adapters: BB30, BBRight, BB86/92, BSA, ITA, T47, and BB386 Evo standards.
