YOUR BUILD HIGHLIGHTS

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.

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.

EXPLORE THE DETAILS

The Arenberg is one of our most iconic models, reimagined as the perfect modern endurance road bike, combining all-day comfort with the legendary performance and lifelong durability of Litespeed titanium.

When you select tubeless-ready wheels and tires, the bike will come from the Litespeed factory with tires set up tubeless with Stan's NoTubes sealant.

If you would like innertubes, you can make a note in the "component request field" on your order, and we will be happy to accommodate.

If you want confirmation whether your specific wheel/tire selection will come tubeless, feel free to contact us via email or chat.

The Arenberg is designed around 700c x 28mm-32mm tires. It has clearance to fit road tires up to 35mm wide.

2x maximum chainring size is 54/40t (Shimano) or 56/43t (SRAM). 1x maximum chainring size is 46t.

Every Litespeed titanium frame is hand-built in the USA, in our factory in Chattanooga, Tennessee, by master framebuilders using premium, globally sourced materials.

The average lead time is 3-4 weeks. This is because every Litespeed titanium frame and complete bike is built to order. You will receive email updates informing you when we begin building and assembling your bike, and when it is shipped from our factory.

The Arenberg is an endurance bike designed for long-distance riding, riding on rough roads, and general all-around road riding.

The Cherohala is an all-road bike designed for long-distance riding and riding a mix of paved and unpaved surfaces.

The Arenberg and Cherohala titanium frames are very similar in terms of weight, construction, and compliance. The main difference is that the Arenberg's geometry and handling are designed around 28-35mm road tires, while the Cherohala's geometry and handling are designed around 35-38mm road and gravel tires. The ideal frame will depend on your preferred tire size and riding terrain.

The Arenberg is an endurance bike designed for long-distance riding, riding on rough roads and mixed surfaces, and general all-around road riding.

The Spezia and Ultimate Disc have more race-oriented geometry and handling, and are built to be slightly lighter and much stiffer. The Arenberg has more upright, endurance-oriented geometry. The Arenberg is slightly heavier, but provides much more comfort and compliance.

The Arenberg is built with Litespeed's Pure LW tubeset. Pure LW is a lightweight titanium tubeset made from aerospace-grade 3AL/2.5V titanium. It is formed, butted, and bent in-house just like our Superform tubes, but omits the multi-dimensional shaping and variable wall-thickness to reduce cost. Pure LW is the ideal choice for bikes that prioritize comfort and durability, while remaining competitively lightweight.
