Denali is a no go!! They use a Non standard freewheel/freehub that NO ONE else uses, or will have a tool to take off. I just had a brand new one come into the shop that was making a grinding thump in the freewheel. We could not take off the freewheel/freehub, so they would need a new wheel, cassette, etc. Bikes direct is one thing, but the denali is made in one size, inferior proprietary parts, etc. You are better off starting with a 90 Trek 1000.,,,,BD

And yeah, I realize I said freewheel/freehub, instead of one or the other. It was such a strange setup I couldn't tell which one it was.
