Standard-Tier Shaped 3AL/2.5V Titanium Tubing
Cable-Free Cockpit Design
T47i BB - Internal Routed System

Fully Controlled Tubesets


We maintain the strictest standards to ensure the best ride. That’s why we go to the effort of not only using size-specific tubesets on the Arenberg to ensure a consistent ride experience, every tubeset is tuned and adjusted to meet our strict wall thickness standards. All the performance, with zero excess weight.

Endurance Geometry


A relaxed riding position, matched with modern features like wide tire clearance allows you to go longer while maintaining the performance edge every Litespeed is known for.

Fully Integrated


The Arenberg FI also incorporates full housing and wire integration. With a selection of cockpits, fork and bottom bracket options, all cables and housing are neatly tucked within the confines of the bar, fork, and frame, and out of the wind. For those demanding a clean, full aero and fully functional cockpit option, there’s no better value in titanium road.
