{"product_id":"sidekick-pro-sp-rear-mtb-hub","title":"Sidekick Pro SP Rear MTB Hub","description":"\u003cp\u003eThe Sidekick Pro SP Anti-Kickback Rear MTB Hub is the choice for trail, all-mountain, and lightweight E-MTB riders building the lightest, stiffest wheel possible without giving up anti-kickback performance. At 275g, it is the lightest hub in the Sidekick lineup: straight-pull spokes, full anti-kickback, and Pro-level upgraded internals in one package.\u003c\/p\u003e\n\u003cp\u003eStraight-pull spokes eliminate the J-bend stress point at the flange and deliver a measurably stiffer, lighter wheel. Combined with the Sidekick platform's full drivetrain isolation near-zero drag, near-silent operation, and tool-free 9°\/13°\/18° deadband adjustment the Pro SP is the build choice for riders who want every possible performance advantage from their hub, without sacrificing on weight. At 9°, engagement is fast and direct, comparable to a conventional hub, ideal when climbing is the priority. Open it up to 13° or 18° for maximum anti-kickback and suspension performance on descents.\u003c\/p\u003e\n\u003cp\u003eInternally, the Pro SP runs EZO driver bearings, TPX hub shell bearings, and nickel-plated steel pawls and pusher. Same World Cup-validated mechanism, tuned for maximum longevity.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e275g\u003c\/strong\u003e the lightest hub in the Sidekick lineup; straight-pull spokes, Boost 148mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEliminate pedal kickback\u003c\/strong\u003e full drivetrain isolation during coasting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNear-zero freewheeling drag\u003c\/strong\u003e at least 55% less than competing hubs in controlled tests\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNear-silent operation\u003c\/strong\u003e hear your tires and terrain, not your hub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool-free deadband adjustment\u003c\/strong\u003e 9° \/ 13° \/ 18°; narrowest setting delivers quick engagement for climbing, wider settings maximize anti-kickback performance\u003c\/li\u003e\n\u003cli\u003eEZO + TPX bearings, nickel-plated pawls and pusher\u003c\/li\u003e\n\u003cli\u003eXD and Microspline driver compatibility Boost 148mm axle, HG driver available for purchase separately\u003c\/li\u003e\n\u003cli\u003e6-Bolt disc mount, 28h straight-pull spoke configuration\u003c\/li\u003e\n\u003cli\u003e17mm alloy axle, ASTM 5 rated at 150kg\u003c\/li\u003e\n\u003cli\u003eE-MTB compatible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-year warranty\u003c\/strong\u003e with lifetime bearing coverage, fully rebuildable, designed for extended service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePair with the \u003ca href=\"\/products\/sidekick-pro-sp-front-mtb-hub\"\u003eSidekick Pro SP Front MTB Hub\u003c\/a\u003e at 129g the lightest front hub in the lineup.\u003c\/p\u003e","brand":"e*thirteen","offers":[{"title":"Boost 148mm \/ XD Driver \/ 28 Hole","offer_id":61727151423858,"sku":"HB5UKA-252","price":349.95,"currency_code":"USD","in_stock":false},{"title":"Boost 148mm \/ Microspline Driver \/ 28 Hole","offer_id":61727151456626,"sku":"HB5UKA-253","price":349.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0063\/3765\/8983\/files\/sidekick-pro-sp-rear-hub-stylized-1-HB5UKA-253.jpg?v=1774985259","url":"https:\/\/www.ethirteen.com\/products\/sidekick-pro-sp-rear-mtb-hub","provider":"e*thirteen","version":"1.0","type":"link"}
