Or saw it off and add a coaster brake typestrap// nutted hub is not QR anyhow..
<[I'm using a ball detent pin, on the reaction strut of my S-A Drum brakes , now for 20 years .
so I only need the 15mm spanner to pull the wheel.. after pulling the ring, that pulls the pin.
the Arai drum unscrews when you brake going backwards , ..
but for it being quite tightened from stopping forward motion.
