Hayden recently approached me wanting to convert a Tune King front hub to QR15 for use on one of the new Fox forks. QR15 uses a thru-axle style quick release of 15mm diameter – hence the name ;-)
At 145g the Tune King is a very light front hub. I machined a preload spacer to sit between the two bearings – this spacer was 12g and can stay in the hub when it’s being used with a standard 9mm quick release. I also machined two endcaps so the hub can accept the 15mm thru-axle .
The factory axle weighs 23g and the new parts I made total 29g so being used as a QR15 hub it should weigh 151g – as far as I know this is the lightest QR15 hub out there :-)
