The short cage is the right choice for double crankset builds with compact or standard cassettes up to 27t. Dura-Ace pulleys with sealed bearings are a genuine performance detail \u2014 these shift with a precision that wears in rather than out. A straightforward, proven upgrade or replacement for any Shimano 10-speed road build.<\/p>\n<p><strong>Guarantee<\/strong> \u2014 You put in the miles, we put in the work. 30-day guarantee on fit, function, and condition. \u2013 Paul<\/p>\n<p><strong>Keywords<\/strong> \u2014 Shimano Dura-Ace RD-7800, rear derailleur, 10-speed, short cage, road derailleur, silver, Japan, 7800 series, Dura-Ace 10s, STI compatible, double crankset derailleur<\/p>\n","protected":false},"excerpt":{"rendered":"<p><strong>Checklist:<\/strong><\/p>\n<ul>\n<li>Gearing range <strong>#10 Speed<\/strong><\/li>\n<li>Shimano<\/li>\n<\/ul>\n","protected":false},"featured_media":16557,"template":"","meta":{"nf_dc_page":""},"product_brand":[],"product_cat":[788,175],"product_tag":[217,1950,234,842,847,1949,271],"product_folder":[930],"class_list":["post-23981","product","type-product","status-publish","has-post-thumbnail","product_cat-rd","product_cat-c-road-bicycle-components","product_tag-10-speed","product_tag-180-grams","product_tag-rd","product_tag-rd-10","product_tag-rd-shimano","product_tag-shimano-dura-ace-rd-7800-rear-derailleur","product_tag-short-cage","product_shipping_class-bike-components-1-lb","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/mybikething.com\/home\/wp-json\/wp\/v2\/product\/23981","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mybikething.com\/home\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/mybikething.com\/home\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mybikething.com\/home\/wp-json\/wp\/v2\/media\/16557"}],"wp:attachment":[{"href":"https:\/\/mybikething.com\/home\/wp-json\/wp\/v2\/media?parent=23981"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/mybikething.com\/home\/wp-json\/wp\/v2\/product_brand?post=23981"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/mybikething.com\/home\/wp-json\/wp\/v2\/product_cat?post=23981"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/mybikething.com\/home\/wp-json\/wp\/v2\/product_tag?post=23981"},{"taxonomy":"product_folder","embeddable":true,"href":"https:\/\/mybikething.com\/home\/wp-json\/wp\/v2\/product_folder?post=23981"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
