✓ Specs checked against the manufacturer
Last checked 4 Sept 2026 against the manufacturer's own page . The weightfigure is our estimate — the manufacturer publishes none. Caveat: Size M geometry row (553mm top tube, Orro's nearest size to a 56cm frame). The 42mm clearance and the front and rear mudguard and pannier-rack mounts are Orro's own statements on its Terra C model page, orrobikes.com/gravel-bikes/terra-c/58; Orro also caps rack loads at 5kg. Orro publishes no claimed weight, so 9.4kg is our estimate for this build. Price listed as GBP 2,399.99.
