Zipp positions it as stiffer than a comfort-oriented post yet more forgiving than a pure race component — a balance that suits riders who spend long hours in the saddle without sacrificing responsiveness. The 20mm setback moves your saddle rearward relative to the rails, giving you the hip-over-pedal position that longer-limbed or more upright riders often need to dial in their fit.\u003c\/p\u003e\n\n\u003cp\u003eA two-bolt clamp system lets you make fine adjustments to saddle angle and fore-aft position without the fumbling that single-bolt designs can involve. Available in three diameters — 25.4mm, 27.2mm, and 31.6mm — it covers a wide range of frame specifications, from older road standards to contemporary builds.\u003c\/p\u003e\n\n\u003ch3\u003eZipp Service Course SL Seatpost Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Carbon fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetback:\u003c\/strong\u003e 20mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamp:\u003c\/strong\u003e Two-bolt saddle clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter options:\u003c\/strong\u003e 25.4mm, 27.2mm, 31.6mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Zipp","offers":[{"title":"Black \/ 25.4mm","offer_id":43522240774188,"sku":"00.6818.056.001","price":190.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ 27.2mm","offer_id":43522240839724,"sku":"00.6818.056.002","price":190.0,"currency_code":"USD","in_stock":true},{"title":"Black \/ 31.6mm","offer_id":43522240872492,"sku":"00.6818.056.000","price":190.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/zipp-service-course-sl-seatpost-20mm-setback-7772749.jpg?v=1771295892","url":"https:\/\/ricycles.com\/products\/zipp-service-course-sl-seatpost-20mm-setback","provider":"RA Cycles","version":"1.0","type":"link"}
