Decided to rely on the manufactures frame size guide, turns out source bmx sizing guide is more accurate, im 5'10 and this frame is slightly too small for my needs but is great for anyone needing a 20.5 top tube length. Chain out of the box is a weak 410 Guage. I'd recommend getting an upgraded chain with your order, I went with a shadow supreme because im a bigger guy, average dudes will only need a shadow interlock V2 probably, also the paint is slightly darker than in the pictures, a well received charcoal black tone
