{"product_id":"specialized-tpu-tube","title":"Specialized TPU Tube","description":"\u003cp\u003eThe Specialized TPU Tube is a next-generation ultra-lightweight inner tube made from thermoplastic polyurethane — far lighter and more compact than traditional butyl rubber tubes, making it an ideal emergency spare carried in a jersey pocket or saddle bag. TPU tubes hold pressure significantly better than butyl over time and weigh a fraction of conventional alternatives. Available in 50mm, 65mm, and 80mm valve lengths — 16 units in stock at Kaptein across sizes.\u003c\/p\u003e","brand":"Specialized","offers":[{"title":"65mm \/ valve","offer_id":57784230248829,"sku":"03025-0301","price":26.0,"currency_code":"EUR","in_stock":true},{"title":"80mm \/ valve","offer_id":57784888689021,"sku":"03025-0302","price":26.0,"currency_code":"EUR","in_stock":true},{"title":"50mm \/ valve","offer_id":57784888885629,"sku":"03125-1000","price":26.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0921\/2775\/6669\/files\/artPic_public_L_4470572.jpg?v=1770213333","url":"https:\/\/kaptein.cc\/nl\/products\/specialized-tpu-tube","provider":"Kaptein - The Complete Cycling Experience","version":"1.0","type":"link"}
