The Super Record Wireless rear derailleur is where that shows up most: fewer cables to route, less to maintain, and shifting that stays consistent whether you're sprinting out of a corner or grinding a climb at threshold.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eWhat the wireless build actually changes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBluetooth shifting\u003c\/strong\u003e — instant, cable-free actuation that also cleans up the cockpit and frame aesthetics most riders care about more than they admit\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eRemovable battery\u003c\/strong\u003e — 750km on a full charge, magnetic quick-snap charging that gets you back to 100% in 60 minutes, status readable via LED or the MyCampy 3.0 app rather than guessing\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eCarbon fibre construction\u003c\/strong\u003e — the weight saving you'd expect, without giving up the stiffness a derailleur cage needs under load\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003ePrecision that holds up ride after ride:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePosition sensor\u003c\/strong\u003e keeps derailleur alignment correct continuously, which is what actually reduces chain wear and keeps energy transfer efficient — not a one-time factory setting that drifts\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eAutomatic cassette adaptation\u003c\/strong\u003e across all three available ranges (10-25, 10-27, 10-29), so shift accuracy doesn't depend on you remembering to reconfigure anything\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eUnLock system\u003c\/strong\u003e — manually free the derailleur to reposition it if something goes wrong mid-ride, then lock it back in with an upward shift; the kind of fail-safe you hope never to need and are glad exists when you do\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eThis is the rear derailleur for riders building or upgrading a full Super Record Wireless groupset rather than mixing generations — check our \u003cstrong\u003e\u003ca href=\"\/collections\/bike-components-groupsets-complete-groupsets\"\u003eComplete Groupsets\u003c\/a\u003e\u003c\/strong\u003e for matched components, or \u003ca href=\"\/collections\/bike-components-groupsets-batteries\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eBatteries\u003c\/strong\u003e\u003c\/a\u003e for spare charged units to swap in on longer stage races.
