Note: The revamped Siskiu T adds UDH compatibility, a reinforced rear triangle, and improved internal cable routing for a sleek, future-proof build. A discreet top-tube mount adds utility, while progressive suspension with a larger volume spacer smooths big hits. A 0.5° slacker head tube, slightly steeper seat tube, and longer reach improve stability and climbing balance without changing the familiar Siskiu ride feel.
Standard measurements are in millimeters and degrees. The site attempts to recognize and convert other units back to standard - results may vary.
