Your custom frame deserves custom components. For our stems and seatposts, we use the same aerospace grade, seamless titanium we use in our frames. As with our frames, we can not only adjust the geometry of our stems and seatposts, but we can design them so they are in keeping aesthetically and functionally with your bike build. This starts with design, tube diameter, angle and setback as appropriate and extends to the finish we apply to the material.

We currently offer stems and seatposts either in conjunction with a custom frameset purchase or available for order individually on our store page.

We invite you to work with us directly. If you’re ready to get your hands on a new Firefly, begin here by completing the correct Firefly Fit Form to the right or contacting Kevin Wolfson at 617.825.3473. (Download Adobe Reader XI to easily fill out, save, and email the fit form.)

After we have an initial conversation and receive your custom fit form, we will set up an in-depth interview to talk about you, your perfect bike, and how we will make it a reality.
