The Signature Stem is fully CNC-machined from billet 7050-T6 aluminum and built around a 35mm clamp interface. Available in 32mm and 42mm lengths to dial in cockpit position and handling.

The 32mm creates a more compact, manoeuvrable setup, suited to shorter riders or anyone after a more agile feel. The 42mm extends reach for a longer, more stable cockpit, suited to taller riders or anyone who wants a more planted ride. Precision setup markings from –10° to 10° are machined in to support consistent bar centering and roll-angle adjustment, removing guesswork during setup.

Designed to pair seamlessly with Signature handlebars while remaining compatible with others. Thoroughly tested to EFBE TRI-TEST Category 5 standards.
