When top EWS Pro Riders ask you to develop a stiffer more durable fork axle, you listen. The stock 15mm axles & other lightweight aftermarket options were simply not tough enough for their race bikes. We don't quite ride at the pace of an EWS Pro, but we loved the simplicity & clean look of the axle so we made them available to buy. Axle F is 98% stronger & stiffer than a stock 15mm axle, yet still 20g lighter than a QR. We've replaced the QR lever with a simple 6mm hex. If you already carry the EDC multitool with you, there's no need for the heavy & bulky QR lever.
