AERON\/TPU is a brand of the German \u003cb\u003eRTI Sports\u003c\/b\u003e group — the company behind Ergon — and is manufactured in \u003cb\u003eAustria\u003c\/b\u003e.\u003c\/p\u003e\n\u003cp\u003ePositioned at \u003cb\u003eLevel 3 “Endurance \/ High Performance”\u003c\/b\u003e in the AERON range, it prioritises balance over record-breaking performance. On the manufacturer’s scale, it scores 75\/100 for puncture protection, 75\/100 for weight saving and 75\/100 for low rolling resistance, whereas a butyl inner tube reaches only 50, 20 and 40 respectively. It is the choice for demanding road riders and touring cyclists who want to cover the miles without punctures.\u003c\/p\u003e\n\u003cp\u003eIn \u003cb\u003e23-28 mm\u003c\/b\u003e, it weighs \u003cb\u003e34 g\u003c\/b\u003e, around \u003cb\u003e66% less\u003c\/b\u003e than an equivalent butyl inner tube — a saving in rotating mass, where it is felt most. It folds down extremely compactly, making a real difference in a saddle bag, and can be repaired with the dedicated AERON puncture repair kit.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eImportant: this inner tube is intended for disc-brake bikes.\u003c\/b\u003e AERON does not approve it for rim brakes, as heat build-up can degrade the TPU.\u003c\/p\u003e","brand":"AERON","offers":[{"title":"42mm","offer_id":57464779604348,"sku":"PBS_AERN081254","price":19.99,"currency_code":"EUR","in_stock":false},{"title":"65mm","offer_id":57464779637116,"sku":"PBS_AERN081255","price":19.99,"currency_code":"EUR","in_stock":false},{"title":"80mm","offer_id":57464779669884,"sku":"PBS_AERN081256","price":19.99,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/3444\/9318\/files\/imgi_5_33330000_detail_1.png?v=1789662665","url":"https:\/\/probikeshop.com\/products\/aeron-extralite-protect-road-inner-tube-700x23-28mm","provider":"Probikeshop","version":"1.0","type":"link"}
