Signature MTB Direct Mount Stem
Signature MTB Direct Mount Stem
The Signature DM Stem is fully CNC-machined from billet 7050-T6 aluminum and built around a 35mm clamp interface. Available in 28mm and 45mm lengths to dial in cockpit position and handling. The 28mm creates a more compact, manoeuvrable setup and sits the bar slightly higher, suited to shorter riders or anyone after a more agile feel. The 45mm extends reach and sits the bar slightly lower 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.

We do offer our Ready2Ride service where we build the bike here at the shop from our mechanics, adjust everything and keep your warranty intact, all you need to do is turn the bars straight and attach the pedals and you are ready to shred!
