All City Bicycles Cosmic Stallion Ti Frameset. Any road. Any way. However you like it, the Cosmic Stallion titanium frameset is ready for the job. We take this capable gravel bike on and off the tarmac thanks to its efficient geometry, and the titanium frame is sure to stand up to the test of time. We appreciate that the frame allows 700c x 45mm or 650b x 42mm tires with or without fenders, letting us adapt to our riding conditions with ease.
