{"product_id":"silca-ultimate-tpu-inner-tube-700c","title":"Silca Ultimate TPU Inner Tube (700c)","description":"\u003cp\u003eSave space and weight in your tyre or in your pack. TPU tubes are less than half the size of a butyl tube, so you can carry two spares where one used to fit, or save 200g+ by replacing the butyl tubes in your tyres.\u003c\/p\u003e\u003cp\u003eSpare TPU tubes have long had weak points: plastic valves that detach, valve cores pressed into plastic that leak, and sleeve joints that fail. SILCA's tubes use a patented mechanical valve-to-tube attachment and a welded joint, plus a threaded aluminium valve that resists heat from electric inflators, with a valve nut for a secure, rattle-free fit. TPU now all but matches latex or tubeless for rolling resistance, at a fraction of the weight.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFor 700c \/ 29in wheels\u003c\/li\u003e\n\u003cli\u003e24–43mm, 50mm valve: 45g; folds to 38 x 77 x 24mm\u003c\/li\u003e\n\u003cli\u003e24–43mm, 70mm valve: 46g; folds to 39 x 95 x 21mm\u003c\/li\u003e\n\u003cli\u003e44–64mm, 50mm valve: 62g; folds to 58 x 77 x 26mm; fits 29er MTB tyres up to 2.5in\u003c\/li\u003e\n\u003cli\u003eThreaded aluminium Presta valve with removable core\u003c\/li\u003e\n\u003cli\u003eRim and disc brake compatible\u003c\/li\u003e\n\u003cli\u003ePatch and alcohol wipe included\u003c\/li\u003e\n\u003cli\u003eValve length: 50mm for rims under 40mm deep, 70mm for 40–60mm rims\u003c\/li\u003e\n\u003cli\u003eNot for use with sealant; safe with CO2 or electric inflators when inflated in 10–15 psi steps\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSILCA Limited Warranty: guaranteed free from manufacturer defects for 2 years.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAvailable from The Cycle Collective in Dorking.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Silca","offers":[{"title":"24-43mm \/ 50mm","offer_id":57351228424570,"sku":"AM-AC-065-ASY-0100","price":39.0,"currency_code":"GBP","in_stock":false},{"title":"24-43mm \/ 70mm","offer_id":57351228457338,"sku":"AM-AC-065-ASY-0200","price":39.0,"currency_code":"GBP","in_stock":false},{"title":"44-64mm \/ 50mm","offer_id":57351228490106,"sku":"AM-AC-065-ASY-0300","price":39.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0487\/4007\/3623\/files\/TPU_Single_front_view_DSC_3535-medium.png?v=1791229941","url":"https:\/\/thecyclecollective.cc\/products\/silca-ultimate-tpu-inner-tube-700c","provider":"thecyclecollective.cc","version":"1.0","type":"link"}
