Many riders moving from older 11-28 cassettes prefer this because it adds easier climbing without massive jumps between gears. Works well with Shimano GS medium cage derailleurs. If a bike has a short cage derailleur, check maximum cassette size before installing. Common replacement cassette for endurance road bikes and gravel bikes using Shimano HG hubs.\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Default Title","offer_id":53170604015930,"sku":"GG-CASS-SHIMANO-105-R7000-1130","price":70.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/5735\/8394\/files\/FW0203-2.jpg?v=1773696068","url":"https:\/\/gograva.com\/products\/shimano-105-cs-r7000-11-30-cassette","provider":"Grava Adventure Corporation","version":"1.0","type":"link"}
