One of our 2019 Radcity has bad axle cone nuts on the front. I’ve looked online but haven’t found them yet. Need 16.9 or 17mm overall diameter, 9mm axle threaded opening, 9.5mm to 11.3mm length (or thickness if holding in hand). The front axle is actually too short on these bikes so the 11.3mm length can’t be exceeded and a little less is better. The hub has Modus on it which helps none so far. Thanks for help on this.
