{"product_id":"livelica-aerolite-frame-4x90","title":"LiveLica Aerolite Frame 4x90 for Inline Speed Skating","description":"\u003cp\u003eThe LiveLica Aerolite 4x90 is the classic four wheel speed frame in the LiveLica AI line. Four 90mm wheels sit low on a compact 10.86 inch platform, giving you the grounded, powerful feel that generations of speed skaters have raced on. It is the frame for track, short course and skaters who want stability and control alongside their speed.\u003c\/p\u003e\n\u003ch2\u003eFour 90mm wheels, the classic speed setup\u003c\/h2\u003e\n\u003cp\u003eThe four by 90 layout is the setup speed skating grew up on, and it endures for good reason. Four wheels give you four points of contact with the ground, which means grip, stability and predictable handling when you load the skate hard through a corner or a start. It is a proven, confidence inspiring configuration that rewards good technique.\u003c\/p\u003e\n\u003ch2\u003eLow ride height, more control\u003c\/h2\u003e\n\u003cp\u003eAt 90mm, the wheels keep you close to the ground. A lower centre of gravity translates into sharper control, quicker direction changes and a more direct connection between your push and the surface. That is why the 4x90 is a favourite for banked track, tight courses and any skating where handling matters as much as raw top speed.\u003c\/p\u003e\n\u003ch2\u003eCompact 10.86 inch platform\u003c\/h2\u003e\n\u003cp\u003eThe 10.86 inch length keeps the frame short and agile, so it turns willingly and feels lively underfoot while still holding four wheels of stability. It is a nimble, responsive platform that suits technical skating and skaters who like to feel the skate move with them.\u003c\/p\u003e\n\u003ch2\u003e124 grams of 7075 T6\u003c\/h2\u003e\n\u003cp\u003eMachined from 7075 T6 aircraft grade aluminium, the Aerolite 4x90 weighs only 124 grams. Carrying four wheels at that weight takes a genuinely strong material, and the light build means less effort lost on every stride and a skate that feels quick to move.\u003c\/p\u003e\n\u003ch2\u003eDual 165 and 195 mounting\u003c\/h2\u003e\n\u003cp\u003eThe frame is drilled for both 165mm and 195mm mounting, so it fits the two common boot standards used across speed and fitness skates. Whichever your boots use, it bolts straight on, and it stays with you if you change boots down the line.\u003c\/p\u003e\n\u003ch2\u003eTuned by AI led engineering\u003c\/h2\u003e\n\u003cp\u003eLike every Aerolite, the 4x90 is the product of AI led engineering. The frame geometry is handed to optimisation software that treats it as a puzzle of forces, keeping metal only along the paths that carry load and hollowing out the rest. The reward is a four wheel frame that holds its stiffness through a hard corner yet still tips the scales at just 124 grams.\u003c\/p\u003e\n\u003ch2\u003eIn the box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAllen key for mounting and adjustments\u003c\/li\u003e\n\u003cli\u003eSpacers\u003c\/li\u003e\n\u003cli\u003eAxles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel setup:\u003c\/strong\u003e 4 by 90mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 10.86 inch (276mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 7075 T6 aircraft grade aluminium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 124 grams\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e dual, 165mm and 195mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e Allen key, spacers and axles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBest for:\u003c\/strong\u003e high performance track and short course inline speed skating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhy a four by 90 frame?\u003c\/h3\u003e\n\u003cp\u003eFour 90mm wheels keep you low and stable with four points of grip, which makes the skate controlled and predictable through corners and starts.
