The Genesis Croix de Fer 20 in Burt Bachablack is a masterclass in functional, timeless design. By sticking with QR dropouts (100mm front/135mm rear), Genesis ensures that this bike remains a practical choice for riders who want a "fix-it-anywhere" machine. The frame is crafted from Mjolnir Seamless Double-Butted Cromoly, providing that signature steel "snap" and vibration damping. The deep Burt Bachablack gloss finish is accented by the new dropped seatstay geometry, which modernizes the look while adding vertical compliance to save your back on long, washboard gravel sectors.
