Fast and Stable Geo
The Meridian was designed to provide stability and confidence on the roughest terrain. The faster you go, the more it rewards you. The low BB provides a planted and stable feeling, while the headtube angle balances stability and a lively response to steering input. Together, this gives the bike a balanced weight split and unparalleled control in all kinds of conditions.

Titanium Construction
Meridian is made of Double Butted Grade 9 3Al/2.5V Titanium. All welds are done with a double pass to match the tubeset in strength and longevity. The Meridian was engineered with a tubeset spec that maximizes speed and efficiency, without sacrificing comfort.

Internal Cable Routing
Our frames are designed to use internal cable routing for mechanical drivetrains, with the option to go fully integrated on electronic drivetrains builds. Cable ports on the downtube that run through the frame allow smooth operation of mechanical shifting. Porting inside the headtube and downtube provide space to allow brake hoses on bikes built using drivetrains without cables.

UDH Hanger
All Luma models come standard with UDH hangers. That means a replacement can be sourced anywhere, anytime with no proprietary parts. It also means compatibility with every derailleur option out there.

BB Cable Cradle
Our T47 bottom bracket shell is designed for ultimate simplicity and ease of use. An access plate underneath leads to a cable cradle that allows each housing to have it's own path. The cable cradle also separate the cable from bottom bracket, allowing for easier maintenance of both components.

Build Options
The Meridian is available as a frameset or a complete. Use the build options to create your dream gravel bike or keep it stock with the standard spec.
