Now it's time for the technology to change road cycling. Even during maximal efforts up a climb or racing a friend, riders no longer need to back off to perform a shift. In any gear, Shimano ULTEGRA R8150 drivetrains maximize efficiency thanks to larger cogs and retain compatibility with existing HYPERGLIDE FREEHUB bodies. All this while increasing to 12-gears, ULTEGRA CS-R8100 cassettes are the new paradigm in road shifting.\u003c\/span\u003e\u003c\/p\u003e","brand":"Shimano","offers":[{"title":"11-30","offer_id":57053607788919,"sku":"ICSR810112130","price":130.0,"currency_code":"USD","in_stock":true},{"title":"11-34","offer_id":57053607821687,"sku":"ICSR810112134","price":130.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0910\/5411\/3143\/files\/cb213de578f2ddd684ebadbd0483455056b95d3a.jpg?v=1777415327","url":"https:\/\/primovelo.cc\/products\/cs-r8101-ultegra-cassette-12spd","provider":"Primovelo","version":"1.0","type":"link"}
