✓ Specs checked against the manufacturer
Last checked 4 Sept 2026 against the manufacturer's own page . Caveat: Size 56 geometry row. BMC's 7.8kg claim is for size 54 with accessories fitted, not size 56. Clearance is BMC's stated 52mm measured tyre. BMC documents no mudguard or rack mounts for this frame — it names them explicitly on the URS — so both are recorded as absent. SKU code 27a is BMC's 2027 model year.
