{"product_id":"ritchey-wcs-1-bolt-tige-de-selle-aluminium","title":"RITCHEY WCS 1-Bolt aluminium seatpost","description":"\u003cp\u003eThe WCS 1-Bolt is a Ritchey aluminium seatpost with 20 mm of setback: the clamp sits behind the axis of the tube, as on most road seatposts. If your current seatpost has a similar setback, the saddle stays where it is.\u003c\/p\u003e\u003cp\u003eThat leaves the diameter. It is usually engraved on the installed seatpost and listed in the frame's specifications; otherwise, a calliper on the old seatpost settles it. Between 30.9 and 31.6 mm, there is 0.7 mm of difference: invisible to the eye, but a seatpost that is too thin never clamps properly.\u003c\/p\u003e\u003cp\u003eRitchey counts 100 mm of minimum insertion within the length: at most 250 mm can stay out of the frame on the 350 mm, 300 mm on the 400 mm. With less insertion, the seatpost levers on the top of the seat tube. If the frame requires more, its figure takes precedence.\u003c\/p\u003e\u003cp\u003eThe 7050 aluminium is thinned from the inside, with the wall staying thick in the line of the loads. At MAAKE, it is the seatpost for 30.9 mm frames, which the \u003ca href=\"\/en\/products\/ritchey-superlogic-1-bolt-flexlogic-tige-de-selle-carbone\"\u003eSuperlogic FlexLogic\u003c\/a\u003e does not cover.\u003c\/p\u003e","brand":"Ritchey","offers":[{"title":"27.2 × 350 mm","offer_id":60032565707077,"sku":"CPT-RITCH-WCS1B-272-350","price":104.9,"currency_code":"EUR","in_stock":true},{"title":"30.9 × 400 mm","offer_id":60032565739845,"sku":"CPT-RITCH-WCS1B-309-400","price":104.9,"currency_code":"EUR","in_stock":true},{"title":"31.6 × 400 mm","offer_id":60032565772613,"sku":"CPT-RITCH-WCS1B-316-400","price":104.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1062\/4181\/8949\/files\/ritchey-wcs-1-bolt-studio-01.webp?v=1793612013","url":"https:\/\/maake.cc\/en\/products\/ritchey-wcs-1-bolt-alloy-seatpost","provider":"MAAKE","version":"1.0","type":"link"}
