My coaster's a bolt on. Not sure if they make a QR coaster hub. I, personally, have never seen one. This is really no matter to me, as a 15mm shorty wrench solves that dilemma and prevents easy wheel grabs. You'd have to disconnect the 'brake arm' from the frame anyway, so the QR axle may be a mute point. Makes for a super clean look though. A LOT of people think it's a fixed gear, until you point out reality to them. Will post a picture as soon as soon as i can get this blasted micro SD thing to work!
