ONLY THE BEST STEEL
Not all steel is made the same, so we made sure to use the best. The 4130 Cr-Mo Steel that we use is super-strong and lightweight. It's much stronger than the "hi-tensile" steels and aluminum used on many bikes, and is literally the same grade of steel used for aircraft. And unlike aluminum, steel absorbs a lot of the shock of the road, even while taking a beating.
Many bikes available online and in department stores are built using 1020 steel, also known as "hi-tensile steel". This is a cheap option that allows manufacturers to build inexpensive bicycles, but it's much weaker than the 4130 steel that we use. To make up for its inherent weakness, bikes built with hi-tensile steel need to have much thicker — and therefore, heavier — frames. If you've ever picked up a bike that felt like a real clunker, it was probably a hi-tensile steel bike.
Meanwhile, our 4130 steel is lightweight enough that our bikes weigh only about 25 pounds (~11.5 kg) — light enough to easily carry up or down a couple flights of stairs.
