{"product_id":"use-seat-post-shim","title":"USE Seat Post Shim","description":"\u003cp\u003eThe Ultimate Sports Engineering shim system allows you to fit a seat post into virtually any frame size. Our shims are made to 100mm length and are longer than other shims on the market giving your seat post much better support inside the frame. All shims are designed with a \"top lip\" to stop the shim sliding into the frame.\u003cbr\u003e\u003cbr\u003eShims are available in Aluminium and Thermo Plastic, despite the latter being a lighter solution its material characteristics limit the thickness of the ID - OD measurements. Aluminium is used to achieve the thinnest shims as it is a more robust material.\u003cbr\u003e\u003cbr\u003eRolled Aluminium shim - the very thinnest shims are rolled from sheet metal. 25.4mm shims need to be so thin as they are etched down in acid to the correct tolerance and are too thin to anodise (shown as silver).\u003cbr\u003e\u003cbr\u003eMachined Aluminium shim - machined to very high tolerances from 6082 T6 Aluminium and then black anodised to protect from corrosion.\u003cbr\u003e\u003cbr\u003eMachined Plastic shim - larger size shims are machined to very high tolerances from \"filled\" engineering thermoplastic UPVC. This keeps the weight down, as the shims get thicker.\u003cbr\u003e\u003cbr\u003eShim design characteristics may affect weight.\u003cbr\u003eWeights are accurate to the nearest gram.\u003cbr\u003eShims allow a rider to adjust the ID of a frame for a range of different sized posts.\u003c\/p\u003e","brand":"Use","offers":[{"title":"25.0 \/ 27.2 - Thermo Plastic","offer_id":31792253632589,"sku":"35571\/SS272","price":9.5,"currency_code":"GBP","in_stock":false},{"title":"30.9 \/ 31.6 - Aluminium","offer_id":43287125131514,"sku":"SS30.9-31.6","price":9.5,"currency_code":"GBP","in_stock":false},{"title":"30.9 \/ 34.9 - Aluminium","offer_id":43287130669306,"sku":"SS30.9-34.9","price":9.5,"currency_code":"GBP","in_stock":false},{"title":"31.6 \/ 34.9 - Thermo Plastic","offer_id":43287137091834,"sku":"SS31.6-34.9","price":9.5,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0269\/3477\/1789\/products\/use-seat-post-shim-35570-p.png?v=1578936785","url":"https:\/\/slam69.live\/products\/use-seat-post-shim","provider":"Slam69","version":"1.0","type":"link"}
