If your seatpost is oval or \"aero\" shaped, then both of our seatposts are not compatible with your bicycle.\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eMy bike has a 25.4mm seatpost.

Since that is larger than 25.4mm, it is not possible to use a shim to adapt the seatpost to your frame.\u003c\/p\u003e","brand":"Redshift","offers":[{"title":"Redshift Seatpost Shim 27.2 - 28.6mm","offer_id":44878542799044,"sku":"SPRS2104","price":39.9,"currency_code":"NZD","in_stock":true},{"title":"Redshift Seatpost Shim 27.2 - 29.8mm","offer_id":44878542831812,"sku":"SPRS2105","price":39.9,"currency_code":"NZD","in_stock":false},{"title":"Redshift Seatpost Shim 27.2 - 30.0mm","offer_id":44878542864580,"sku":"SPRS2106","price":39.9,"currency_code":"NZD","in_stock":true},{"title":"Redshift Seatpost Shim 27.2 - 30.9mm","offer_id":44878542897348,"sku":"SPRS2102","price":39.9,"currency_code":"NZD","in_stock":true},{"title":"Redshift Seatpost Shim 27.2 - 31.6mm","offer_id":44878542930116,"sku":"SPRS2101","price":39.9,"currency_code":"NZD","in_stock":false},{"title":"Redshift Seatpost Shim 27.2 - 31.8mm","offer_id":44878542962884,"sku":"SPRS2103","price":39.9,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1566\/6131\/files\/eyJidWNrZXQiOiJ3ZWItbmluamEtaW1hZ2VzIiwia2V5IjoicHJ2YjJibXlvYmFcL2ltYWdlc1wvcHJvZGltZ1wvMzkwMTZfMS5qcGVnIiwiZWRpdHMiOnsicmVzaXplIjp7IndpZHRoIjoxMjAwLCJoZWlnaHQiOjEyMDAsImZpdCI6Imluc2l.jpg?v=1748205037","url":"https:\/\/www.chainreaction.co.nz\/products\/redshift-seatpost-shims","provider":"Chain Reaction","version":"1.0","type":"link"}
