SURGICAL HANDLING

Nothing handles like an Ultimate Disc FI. Sporting a proven road race geometry, the Ultimate FI Disc can dive into corners, carve on a rail, climb with grimpeurs, and sprint with unyielding stiffness. Quite simply, the Ultimate Disc FI does it all.

PERFORMANCE-DRIVEN TUBE SHAPING

Litespeed’s longest-standing road race ride remains as it ever was on the hunt for the front of the race. And that’s achieved by way of masterfully shaped titanium tubes. From an aero-shaped teardrop downtube to our quadrilateral-formed top tube delivering exceptional stiffness, every tube has been cold-worked with a single purpose in mind: smooth, fast road performance.

TIRE CLEARANCE

Be ready for it all. With tire clearance up to 35mm on disc brakes, the Ultimate Disc FI can run fast and far on tires and wheels with the volume and compliance you demand. Tackle anything from technical crits to big, carving descents to rough broken roads.

EXPLORE THE DETAILS

Litespeed introduced the Ultimate in 1987, and when it was released, it was our “ultimate” road bike. It’s been refined and perfected over decades and remains the benchmark that all other titanium bikes are measured against.

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.

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

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

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 Ultimate Disc is a road racing bike designed for road racing, crits, and general high-performance road riding.

The Spezia and Ultimate Disc have very similar race-oriented geometry and handling, but the Ultimate frame is slightly more compliant and a bit heavier, making it slightly more comfortable. The Arenberg has more upright, endurance-oriented geometry. The Arenberg is heavier, but provides even more comfort and compliance.

The Ultimate Disc is built with Litespeed's Superform SL tubeset. Superform SL is a superlight titanium tubeset that sets the benchmark for advanced titanium bicycle tubes. Superform SL is an aerospace-grade 3AL/2.5V titanium tubeset that is custom-formed and hand-crafted in-house, allowing us to employ multi-dimensional shaping and variable wall-thickness to minimize weight and maximize performance.
