TrikTopz Parts & Accessories

TrikTopz make novelty valve stem caps and small finishing pieces — dice, skulls, flags, bullets, and a few hundred other shapes machined to fit standard Schrader valves. Made in Southern California, properly machined rather than cast plastic, and they actually keep dirt out of the valve stem so they're functional as well as decorative.

Cheap, easy to swap, and the kind of small custom touch that makes a stock bike feel a bit more personal without committing to bigger work. Plate bolts and similar small pieces round out the range.
