TheOneUp RockShox Axle is the result of top EWS Pro Riders asking for a stiffer more durable fork axle. The stock 15mm axles and other lightweight aftermarket options were simply not tough enough for their race bikes. We don't all ride at the pace of an EWS Pro, but One Up loved the simplicity and clean look of the axle so they made them available to buy. Axle F is 98% stronger and stiffer than a stock 15mm axle, yet still 20g lighter than a QR. One Up 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 and bulky QR lever.OneUp RockShox Axle Features98% Stiffer and stronger than stock 15mm QR thru-axle20g Lighter than stock QR thru-axleLow profile hex head won't get caught on trailside obstacles ...
