FORM G50.1 — Steel Gravel Frameset
Built in Copenhagen for riders who want to go further off the beaten path without giving up steel's signature ride feel. The G50.1 pairs a Columbus Spirit and Life tubed front triangle with a Safi-developed rear triangle, then layers on genuinely progressive geometry — a steeper seat tube, longer reach and higher stack — for a capable, all-day gravel position.
Every frameset-specific component — fork, head tube, dropouts and seatpost clamp — is designed in-house, yet stays fully compatible with aftermarket parts, so you can build it up exactly how you want without getting locked into proprietary solutions. With clearance for tyres up to 50 mm, it's ready for anything from fast gravel roads to genuinely rough terrain.
