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 Flint is our most adventure-oriented gravel bike, with relaxed geometry, more tire clearance, and our most robust and affordable tubeset. It's ideal for gravel riders who want a do-it-all gravel bike for everything from bikepacking to racing.

The Toscano and Ultimate G2 have slightly more race-oriented construction, geometry, and handling, and they are built with a lighter and stiffer titanium tubeset, which increases cost.

1x maximum chainring size is 42t. 2x maximum chainring size is 48/31t.

The Flint has clearance to fit gravel tires up to 700c x 54mm wide with a 1x drivetrain.

With a 2x drivetrain, tire clearance is reduced to 700c x 50mm due to the front derailleur.

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 Flint 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.

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.
