Nice vid. I like the hot glue alternative (however it has to be reasonnable otherwise it won't fit the cover anymore!).

As for the slit in the replacement cover for the zero, it may help to sew a point or two on each end to avoid tearing because of the cover torsion.

Next step: tutorial on how to make the equivalent of a saddle foam out of a swimming pool noodle :P

Since the replacement cover uses a drawstring do you need the slit at all? Could you just remove the cover to make adjustments?

I've never used one of the drawstring covers, so maybe that would be too annoying in practice.

From experience of adjusting a Fusion Zero and Fusion One, I can imagine it would be quite annoying.
The seatpost bolt is one that you should also check regularly for tightness. The hollow bolt in the Fusion Zero also has a habit of snapping in two when it comes loose.

Today I did my 2nd saddle and I can confirm again that cutting a new foam is a really really easy trick. My first saddle was great. Haven't tryed yet my new version.
Replaceble cover makes all the job even faster (it takes me about 45'), but it looks not so beutiful as a stapled cover.

Tomorrow will post a picture

Tell us more about cutting the foam. What kind of foam? What tools did you use?

[MuniAddict]

The other thing you can try is adding a piece of less firm foam on top of the original zero foam. I used two pieces placed on either side just in the sit bone area which retains and even emphasizes the cut out area while adding more cushion to the sit bone area, possibly resulting in something closer to the new Fusion one. It elevates the sit bone area so that the foam immediately in front that would normally be pushing against your crotch area is now much lower and more out of the way.

Far too much trouble since you would have to also remove the lift handle and bracket if you're using the T handle plus the rear bumper in order to remove the cover. You might be able to just remove the rear bumper and peel it off the back and expose the bolt to the pivotal seatpost. By contrast making a small slit in the cover is by far the more practical solution.

Fair enough. I haven't used the pivotal bolt/interface on my Zero (mine is on a Shadow base), but I'm surprised at the reports of it needing frequent tightening. I use the Shadow base (also Pivotal) on my 36er and it's never come loose for me. I last touched it ~2.5 years ago when I put in a longer seatpost. YMMV I guess...
