TOMII CYCLES Handmade Brass Top Cap 2026

A piece too beautiful to be true, just like Indian jewelry!

TOMII CYCLES is a custom frame builder in Austin, Texas. Nao Tomii, a.k.a. Nao Tomii, has a unique career, having studied fine arts in the U.S., worked as a sculptor and 3D modeling in Boston, Massachusetts, and then started building frames.

The bicycles he creates have a delicate, nostalgic feel like Indian jewelry, yet are fused with cutting-edge imagery, and the bikes he creates with the motto of making bicycles that are fun to ride have a unique presence.

For the past few years, as well as custom-ordered frames, we have been focusing on the production of beautiful parts such as brass top caps, spacers, and bells.

Even these brass stem caps are individually engraved by Nao's hand, and no two are alike.

All parts are patinaed (chemically changed in color) and then finished with wax, allowing the brass to age well.

Some of them are inlaid with turquoise or opal, which, like the detail work on the frames he creates, is as beautiful as Indian jewelry.

This item would make a great addition to your own bike, or as a gift for a loved one or riding companion.

*Comments from Nao about care

As for the maintenance of brass parts, all parts are waxed after patina (chemical color change). (Because if you do lacquer or clear coat, the texture is not good.)

So the color will change over time (even the grease from your hands will weather it). That is one of the interesting things about brass, but if you wax it regularly (especially after touching it with your hands) or wipe it with a soft cloth, the original patina will last longer. (It's like a jewelry store.) Wax is fine for cars, wood flooring, whatever.
