Don't worry, not another "how much do you love/anti-love these wares" thread.
Just had a question regarding the "sized for aluminum" units. Even oversized, the pocket in the tensioner is not wide enough to accomondate the frame fork end + aluminum insert. Is it safe to run them just contacting the edges of the fork end, or should I look at shaping them to drop into the tensioner. The MKS itself appears to be cast, so I think it might be easier to grind the "soft" aluminum pad (read: replacable mounting surface in the fork ends) in order to make it fit.
I guess all this boils down to is: has anyone tried re-shaping the MKS tensioner (wide one) to fit "extra-wide" aluminum fork ends, or is it not worth bothering (and just running them as is).
An associated question, does the eyelet in the tensioner run between the hub and frame, or frame and nut? I can see in the later that it would be significantly more important to have a nice snug fit with the tensioner, given that if it slipped you'd lose a bunch of chain tension in a hurry (the eyelets are not serrated like track nuts are). I guess the hub locknuts are serrated as well, so perhaps the point is moot. I've worked with BMX style tensioners before, and it's quite obvious they need to be on the outside, but with these going down the middle of the fork end it's a bit ambiguous.
