Problem with the Almax (I have one) is that you need a support vehicle following you as it is sooo heavy. Great chain though..
Yes it does. Check the videos of it. You use the spacers supplied to get it to line up with a hole in the disc. Then it finds the same ones everytime
You can lock it before it's lined up, then roll the bike forward to 'lock' it. This engages the spring loaded pin.
I went to order since they had a 15% discount code, but when it wouldn't take it i didn't bother buying. I really like the idea though
