ONE 80 pairs 80mm wheels with a 243mm frame; ONE 90 uses 90mm wheels on a longer 273mm frame. The shorter setup is the more compact choice for frequent turns. The larger-wheel option favors carrying momentum along open paths and longer city routes.

The ONE platform uses 165mm frame mounting, a ratchet ankle closure and heel shock absorption. That removable-frame design gives you options beyond the original setup, but a replacement still needs the correct mounting spacing, wheel clearance and hardware.

Compare the complete wheelbase, not just wheel diameter. ONE 80 uses a 243mm frame and four 80mm wheels; ONE 90 uses a 273mm frame and four 90mm wheels. Choose the more compact setup for frequent turns, or the longer, larger-wheel setup for open routes.

The manufacturer specifies 165mm mounting on ONE 80 and ONE 90. A replacement frame must match that mounting standard and the boot’s clearance and hardware requirements. Sharing a mounting measurement does not make every possible wheel setup compatible.
