{"product_id":"box-one-m30-m-cranks","title":"Box One M30 Crankset","description":"\u003cp class=\"p1\"\u003eAll Box One and Box Two cranksets are engineered around Box’s Oversized Technology™ platform with one primary objective: maximizing pedaling stiffness and power delivery. There is little benefit in pushing harder on the pedals if that energy cannot efficiently transfer to the rear wheel.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eTo reduce lateral deflection at the bottom bracket, Box enlarged both the spindle diameter and crank arm interfaces. Material was strategically removed from low-stress zones and reinforced in critical high-load areas to optimize stiffness while minimizing unnecessary weight. The result is improved drivetrain efficiency, faster acceleration response, and reduced energy loss under sprint loads.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe Box One M30 crankset brings the same aggressive oversized design philosophy as the flagship M35 system but scaled specifically for smaller BMX racers. The 30mm spindle offers extreme stiffness relative to lighter riders, delivering a similar ride characteristic to what the M35 provides for elite pro-level racers.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe crank arms are hollow-forged and proportionally refined for their intended application. Box carefully balanced stiffness and ride feel, recognizing that excessive stiffness beyond a certain point simply adds unnecessary material and weight without additional rider benefit. To further optimize weight savings, the stabilizer rings found on the M35 spider were removed, along with additional material from low-stress spider zones.\u003c\/p\u003e\n\u003cp class=\"p1\"\u003eThe result is a lightweight, highly responsive crankset engineered specifically for smaller BMX racers seeking elite-level power transfer and acceleration.\u003c\/p\u003e\n\u003cp class=\"p2\"\u003eFeatures:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOversized Technology™ platform\u003c\/li\u003e\n\u003cli\u003e30mm oversized spindle system\u003c\/li\u003e\n\u003cli\u003eOptimized pedaling stiffness and power transfer\u003c\/li\u003e\n\u003cli\u003eReduced lateral flex under sprint loads\u003c\/li\u003e\n\u003cli\u003eHollow-forged crank arm construction\u003c\/li\u003e\n\u003cli\u003eLightweight spider design with optimized material placement\u003c\/li\u003e\n\u003cli\u003eFast and responsive acceleration feel\u003c\/li\u003e\n\u003cli\u003eEngineered specifically for smaller BMX racers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"p2\"\u003eSpecifications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSpindle Diameter:\n\u003cul\u003e\n\u003cli\u003e30mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eConstruction:\n\u003cul\u003e\n\u003cli\u003eHollow-forged crank arms\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eIntended Rider:\n\u003cul\u003e\n\u003cli\u003eSmaller BMX racers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"p2\"\u003eCompatibility:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with Box \/ Praxis M30 bottom bracket systems\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Box Components","offers":[{"title":"145mm \/ Black","offer_id":44622374109465,"sku":"BX-CK14VM145-BK","price":499.99,"currency_code":"CAD","in_stock":false},{"title":"150mm \/ Black","offer_id":44622374142233,"sku":"BX-CK14VM150-BK","price":499.99,"currency_code":"CAD","in_stock":true},{"title":"155mm \/ Black","offer_id":44622374175001,"sku":"BX-CK14VM155-BK","price":499.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/7477\/5321\/products\/Box_M30M_v004.040.jpg?v=1677329106","url":"https:\/\/www.bikesupplies.com\/products\/box-one-m30-m-cranks","provider":"BikeSupplies.ca","version":"1.0","type":"link"}
