If you are hunting for the best and lightest inline skating frame, you already understand something important about speed skating. The frame is the one piece of your skate that carries every wheel, every bearing and every gram of your effort straight into the ground, and its weight is mass you lift and swing on every single stride. Shave weight off the frame and you feel it all day, in fresher legs, quicker feet and a skate that snaps under you rather than dragging. This guide ranks the lightest inline speed skating frames LiveLica makes, explains exactly why they are so light, and helps you pick the right one for how you skate. Every weight quoted here comes straight from the product specifications, so you are comparing real numbers, not marketing.
Why frame weight matters more than you think
Your frame sits at the very bottom of the skate, furthest from your body, which is the worst possible place to carry extra mass. Weight down there has to be accelerated and decelerated with every stride and every recovery, so it costs you far more effort than the same weight sitting near your hips. Over a marathon that is thousands of strides, and the grams add up into real fatigue. A lighter frame also feels more agile, changes direction more willingly and lets the skate follow your foot instead of fighting it. That is why the lightest frame you can run, without giving up stiffness, is one of the most effective upgrades in the sport.
The lightest inline skating frames, ranked by weight
Here is the full LiveLica Aerolite range ordered from lightest to heaviest, so you can see at a glance where each frame sits. Every one is machined from 7075 T6 aircraft grade aluminium, the same alloy family used in aerospace, and every one ships with an Allen key, spacers and axles in the box.
The 90x3 leads the range at 114 grams. Even the biggest four wheel frame stays under 160 grams.
Aerolite 90x3, the lightest at 114 grams
The Aerolite 90x3 is the flagship and the lightest frame in the range at just 114 grams. It runs three 90mm wheels on a short 9.5 inch platform, a versatile racing setup that mixes top speed with sharp agility and quick acceleration. It is also the only frame here drilled for both 150mm and 165mm mounting. If your single goal is the lowest possible weight under your boot, this is the top pick, and it is the frame the rest of this list is measured against.
Aerolite 4x90, low and agile at 124 grams
The Aerolite 4x90 weighs 124 grams and carries four 90mm wheels on a compact 10.86 inch platform. Four smaller wheels keep you close to the ground for a low centre of gravity, sharp control and grippy, predictable handling. It is the classic track and short course setup, and carrying four wheels at this weight is exactly what the 7075 T6 alloy is for.
Aerolite 4x100, the versatile all rounder at 148 grams
The Aerolite 4x100 comes in at 148 grams and runs four 100mm wheels on a 12.1 inch platform. This is the do it all frame, balancing the quick handling of smaller wheels with the rolling speed of the big ones. If you want one light frame that trains, tours and races, this is the sensible middle of the range.
Aerolite Hi Lo 3x110 plus 1x100, distance frame at 154 grams
The Aerolite Hi Lo is exceptionally light for a full four wheel road frame at 154 grams. It mixes three 110mm rear wheels with a single 100mm front wheel on a long 12.9 inch platform, which builds in a slight forward pitch for sharper acceleration and a lively rolling feel over distance. It uses the 195mm mounting standard.
Aerolite 3x125, big wheel triskate at 155 grams
The Aerolite 3x125 weighs 155 grams and carries three 125mm wheels, the largest common diameter, on a 12.6 inch platform. Fewer wheels mean less rolling resistance and less weight, so you get maximum rollout and serious top speed in a frame that still turns willingly. It is a favourite modern setup for road and distance skating.
Aerolite 4x110, full race frame at 159 grams
The Aerolite 4x110 is the longest and fastest four wheel frame in the range, and even at 13.2 inches with four full size race wheels it weighs only 159 grams. The long platform tracks dead straight and stays composed at race pace, making it the planted, all out choice for competitive road and marathon skating. It is the heaviest frame here, yet it is still lighter than many rivals that carry fewer wheels.
What actually makes these frames so light
Two things do the work. The first is the material. Every Aerolite is machined from 7075 T6 aircraft grade aluminium, an alloy chosen for its exceptional strength to weight ratio. It lets the frame stay thin and hollow where a weaker metal would need to be thick and heavy. The second is the shape, and this is where the range earns the LiveLica AI name.
Optimisation keeps metal only where force actually flows and opens up the rest, so the frame stays stiff while the weight falls away.
As part of the LiveLica AI line, each Aerolite is shaped by AI assisted generative design. The software treats the frame as a puzzle of forces, runs through countless load cases, and learns exactly where the metal must stay to carry the load and where it can be hollowed out. The skeletal cut out structure you see is the result. That is how a frame reaches its low weight while holding the rigidity a hard sprint or a long push demands. Stiffness matters here, because a light frame that flexes wastes the very energy you saved. The whole point of the optimisation is to keep both, low weight and high stiffness together.
Lighter is not always the right answer
The lightest frame on paper is not automatically the best frame for you, because weight is only one part of the picture. Wheel size and platform length shape how the skate behaves just as much. Smaller wheels on a short frame feel low, sharp and agile, while big wheels on a long frame roll further and stay planted at speed. The Aerolite range keeps the weight low across all of those choices, so you can pick the setup that suits your skating and still get a featherlight frame.
Move left for a short, agile, ultra light setup, or right for a long frame that carries speed. The whole range stays light.
Which lightest frame should you choose
If your only priority is the absolute lowest weight and a quick, agile three wheel feel, the 114 gram Aerolite 90x3 is the clear winner. If you race on the track and want a low, controlled four wheel platform, the 124 gram 4x90 is the lightest four wheel option. For one frame that handles training, road and fitness, the 148 gram 4x100 is the versatile pick. For distance and marathon skating, choose the 154 gram Hi Lo for its forward pitch or the 155 gram 3x125 for pure big wheel rollout, and step up to the 159 gram 4x110 when you want the longest, most planted race platform. Whichever you choose, you are getting an aircraft alloy frame under 160 grams, so no option on this list is a heavy one. You can compare the whole lineup side by side in the LiveLica AI Frames collection, then pair your chosen frame with your usual wheels and 608 bearings.
Frequently asked questions
What is the lightest inline skating frame LiveLica makes?
The Aerolite 90x3 at 114 grams is the lightest in the range. It runs three 90mm wheels on a short 9.5 inch platform and is the flagship of the LiveLica AI line.
Why are these frames so light?
Two reasons. They are machined from 7075 T6 aircraft grade aluminium, which has an excellent strength to weight ratio, and they use an AI optimised skeletal structure that keeps metal only on the load paths and removes the rest. That combination gives low weight without sacrificing stiffness.
Does a lighter frame really make me faster?
It helps, because frame weight sits low on the skate where it costs the most effort to move on every stride. A lighter frame reduces that effort and feels more agile, though technique, wheels and bearings all matter too. Weight is one lever among several.
Will these frames fit my boots?
Most of the range is drilled for two mounting standards, so it fits the common boot patterns, though the exact standards vary by model. Check the mounting listed on each product page against your boots before ordering, and message the team if you are unsure.
Do the frames come with everything I need to mount them?
Yes. Every Aerolite frame includes an Allen key, spacers and axles in the box, so you have the hardware to fit the frame and set up your wheels.
