Legendary Japan based BMX brand Kuwahara is still making their popular Lachesis BMX racing frames. Their latest iteration of the Lachesis is the “Omega” model and its been around for a few years. The Omega is a completely different frame design from the regular Lachesis Pro. It features a BB86 bottom bracket, hydroformed and tapered top and down tubes and tapered head tube. The dropout can fit 20mm and 10mm axles. It has a big 31.6mm seat tube which fits a 34.9mm seat clamp. Two notable differences with this frame from the rest is the slacker 73.5 head tube angle and the 74 degree seat tube angle. Pretty interesting.
