Grumm, my comment about maxle 360 20mm, saying in brackets 'that's not quite bolt through' or something like that was because to be honest I am not too hot on all the latest standards for QR and the like.
I have QRs on my bike, they work, so I don't really see the need to change.
But now there are 15mm/20mm/Maxles etc. and I thought that bolt through were actually bolted up, rather than QR, which I think the maxle is. Could be wrong though.
Does that make any sense at all?!
