JAGi Dropper Post

The EXA Form Jag-I is a reliable, value-focused dropper seatpost designed for riders who want modern dropper functionality in frames requiring a 27.2 mm seatpost diameter.

With 120 mm of smooth, controlled travel, the Jag-I allows riders to quickly lower the saddle for descents and technical sections, then return to full pedalling height at the touch of a lever. Its proven internal mechanism delivers consistent performance for trail and mountain riding, making it an ideal upgrade for bikes not compatible with larger-diameter droppers.

Constructed from durable aluminium and supplied with a handlebar-mounted remote, the Jag-I offers dependable performance at an accessible price point — perfect for trail, hardtail, and older MTB frames.
