HI I want to know if a Quick Release 20mm Hub works like a Througaxle hub, my question exactly is if the axle of the QR can came out like the Througaxle, if it is posible how I can take apart the axle? Thanks!! :evil:

Are you talking about Marzocchi? Their current 20mm hubs work just like everybody elses. Are you aware that a 20mm hub is 110mm wide, and that a QR is only 100mm? Just checking. Your question is kind of vague.
What is different is the width of the dropouts. 20mm hubs from any mfg will fit all forks w/ 20mm dropouts, but the axles are unique to a fork.
I checked to see if a Marz 20mm QR would fit a Boxxer, and it does not.
Hope that helps.

yhea that is the problem I tried to use it with the Boxxer but the boxxer is througaxle and not QR
Both are considered through axle. Its just that Marz uses a qr in place of bolts to tension the axle. Kind of confusing.

It sounds like you've already removed the QR skewer and the end cap it threads into but your axle is still stuck in the fork. With QR20 systems you can leave the skewer in the hub just like you would with a standard quick release hub but you remove the pinch bolts and the little tabs below the axle will come off, or swing away depending on which year fork you have. You can then drop the hub out of the dropouts just like a standard dropout. If you want to do things the difficult way you could remove the skewer, loosen but don't remove the pinch bolts and then push the axle through the dropout like on a regular through axle fork.

Put it back together the same way but in reverse. FYI the pinch bolts don't need to be very tight.

Ok I used a mallet to take apart the axle and it cames out with the bearing, and the axle is litle bit thin than the axle of the boxxer, and the axle of this hub have a two edge in the middle where the bearing settle, I tried to use the Boxxers axle, and it doesnt fit into the spacer, and I think this kind of hub is not for boxxer's the axle is not a thougaxle, so I decided to sell it. Thanks a lot for your help

I hope you understant what I try to explain, I dont no to much english so sorry for my gramma errors Thanks

I was told by Marzocchi that the original QR20 hub can only be used on a QR20 fork. They make an adapter for a standard 20mm hub for the QR20 but it doesn't work the other way around. As you found out.
