I have a 7-speed (11-13-15-18-22-26-34) MegaRange cassette that I'm trying to use on an old Shimano FH-M732 Deore XT hub. The cassette has the 5 larger gears fixed together and the 11 & 13 are loose. However, the 11 has a "shoulder" built into that stops it when it slides onto the hub body. When I install the cassette and tighten down the lockring, it doesn't completely tighten up the cassette. The 13 is still loose. The shoulder on the 11 keeps it from pressing down onto the 13 when the lockring is tightened.
If the 11 were installed by itself on the hub, it wouldn't go any further than it does with the rest of the gears. This cassette was new-in-the-box when I got it. As such, I think all of the parts are there. There is a spacer between the 13 and 15. The 11 with the shoulder is the correct thickness to set the proper spacing between it and the 13.
I can get it to tighten up by putting a spacer behind the entire cassette, but I'm worried that I won't have clearance between the 11 and the chainstay because it pushes the entire cassette that direction. When I do this, there isn't a whole lot of room left between the outer face of the lockring and the drive side axle locknut on the hub.
The hub is one of the older ones that has both internal and external threads. I have a different 7-speed HG hub that fits perfectly and snugs right up.
What gives with the hub that has the shouldered 11 gear? I guess I could replace the 11 on it with a "normal" 11 and it would work fine.
Any input would be appreciated.
