It replaces the stock pulley cage with 13-tooth and 19-tooth aluminum pulley wheels — larger than Shimano's stock pulleys, which reduces how sharply the chain has to bend as it travels through the derailleur and cuts down on friction at the source.\u003c\/p\u003e\n\n\u003cp\u003eEach pulley runs on CeramicSpeed's coated ceramic bearings, with hardened stainless steel races and a metallic coating that CeramicSpeed states makes the bearing rings 75% harder than standard steel. The cage is carbon fiber reinforced polyamide, chosen for a stiff, lightweight structure that holds the pulleys in precise alignment. All told the system weighs around 77 grams. CeramicSpeed's own testing puts the friction reduction at 30-60% over a stock Shimano pulley setup, translating to a claimed savings of roughly 2.4 watts — a manufacturer figure from their lab testing rather than an independently verified number, though the combination of larger pulleys and ceramic bearings is a well-established way to reduce drivetrain drag.\u003c\/p\u003e\n\n\u003cp\u003eThis is a component built for Shimano's previous-generation 11-speed Dura-Ace and Ultegra Di2 or mechanical groupsets, not the current 12-speed 9200\/9250 lineup, so it's worth confirming which generation your bike runs before ordering. At $449.25, marked down from $599, it's a way to get CeramicSpeed's coated bearing technology and a distinctive gold finish at a discount on an older but still widely-ridden groupset generation.

At 225g, it's not a weight-weenie component, but it's one that earns its place on the bike through consistent, low-maintenance shifting ride after ride.\u003c\/p\u003e\n\n\u003ch3\u003eShimano 105 RD-R7000 SS Rear Derailleur Specs at a Glance\u003c\/h3\u003e\n\u003cul class=\"specs_at_a_glance\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 225g\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChain Compatibility:\u003c\/strong\u003e HG-EV 11-Speed \/ HG-X11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCassette Range:\u003c\/strong\u003e 11-25 to 11-30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Shimano","offers":[{"title":"Black","offer_id":43519844712492,"sku":"IRDR7000SSL","price":70.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/shimano-105-r7000-ss-rear-derailleur-9324497.jpg?v=1771298117"},{"product_id":"shimano-105-fd-r7000-34-9mm-clamp-on-front-derailleur","title":"Shimano 105 FD-R7000 34.9mm Clamp-On Front Derailleur","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003eShimano 105 FD-R7000 34.9mm Clamp-On Front Derailleur\u003c\/strong\u003e brings the mechanical refinements of Shimano's upper-tier groupsets down into a package built for everyday riding and long-term reliability.
