ULLICYC SP20 Carbon Seat Post 400mm 0° Offset S5 Frame 231g S2 S3 S-Series

ULLICYC SP20 Carbon Seat Post Features Specs and S-Series Compatibility

At only 231g ultralight weight, the SP20 is among the lightest direct-fit options available for S-Series frames, saving meaningful grams compared to stock aluminium alternatives at the same stack height. The 400mm length provides ample adjustment range, allowing riders of different proportions to dial in their saddle height precisely without cutting the post shorter than necessary. A 0° offset positions the saddle directly over the bottom bracket, a geometry that suits aggressive road and criterium riders who prefer a forward position and efficient pedalling mechanics. The 52x10mm clamp head is dimensionally matched to S2, S3, and S5 frame seat tube openings, eliminating compatibility guesswork that can lead to costly fitment errors.
