If you're a Luddite, then the standard QR that comes with Stan's light and lively wheels will work fine. On the other hand, if you're a technophile, then you'll want to pop for the 15mm Conversion for ZTR/3.30/3.30Ti Front Hub. Simply remove the standard QR end caps, install these units and you'll be riding on the stiffer 15QR standard in no time.
