Catrike Boom Clamp Assembly - Unlike other trike manufacturers, Catrike does not have welded bosses on the bottom of their frame to clamp the boom, but rather uses a clamping assembly that wraps around the frame. The Boom clamp assembly is used on all current Catrike models and with some modification can be used on even the oldest models.

Catrike Mirror/Computer Mount (Right) - A mount that attaches to the lower handle bar for the use of a mirror or a computer display. Angled forward for the right side.
