YOUR BUILD HIGHLIGHTS

METICULOUSLY SHAPED 3AL/2.5V TITANIUM FRAME

With performance-focused titanium manipulation capabilities unique to Litespeed, the G2 showcases our unique in-house tube manipulation technologies on a level not seen in the industry. The result is a ride experience that rivals that of any titanium gravel bike out there.

FULLY INTEGRATED

The Ultimate G2 Fi delivers more top-tier performance than ever. It's all finished with our premium fully- Integrated option; a handlebar, stem, fork, and bottom bracket system that allows for internal cable and wire routing. With no external housing, your Ultimate G2 FI becomes the cleanest rig on the start line.

A VISUAL SIGNATURE: INTERLOCK DROPPED SEATSTAYS

By vertically dropping and widening the stays—and extending them past the seat tube to the top tube—the Ultimate G2 has two independent stiffness-enhancing weld points, resulting in an infinitely more responsive rear triangle, with stiffer out-of-saddle acceleration.

LIFETIME WARRANTY

Ride with peace of mind knowing that your Litespeed bike is covered for life by our rider-first warranty.

All Litespeed gravel bikes come from the 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.

Fork choice will depend on your riding preferences and terrain.

A gravel suspension fork will add comfort and confidence on rough terrain, but it will weigh more than a rigid carbon fork, and it may feel less efficient (due to flex, weight, or pedal bob) on smooth terrain.

A rigid fork is lighter, and it also provides a bit more tire clearance and mounting options for extra gear and bags, but it will transmit more shock from impacts and vibration from rough roads.

For more information on gravel suspension forks, read our detailed thoughts on gravel suspension here.

The Ultimate G2 is a gravel bike designed for tackling gravel terrain at high speeds. It is ideal for gravel riders who want a light and fast titanium gravel bike for a mix of racing, exploring, and general gravel riding.

The Toscano has similar geometry and handling, but its titanium tubeset is lighter and stiffer to suit more race-focused gravel riding. The Flint has a more relaxed, adventure-oriented geometry, more tire clearance, and a different tubeset, which makes it slightly heavier but provides more robustness and affordability.

1x maximum chainring size is 46t. 2x maximum chainring size is 48/31t.

The Ultimate G2 has clearance to fit gravel tires up to 700c x 50mm wide with both 1x and 2x drivetrains.

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 G2 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.

The maximum recommended load of 3 kg (6.6 lbs) per leg when attaching items to the accessory mounts on the Litespeed Rigid Carbon Gravel Fork with Accessory Mounts.
