I cut my DX seat down today and removed a little more than an inch all around. I managed to do it without having any gaps between the bumper and handle. When I put it back on, the seatpost bolts stuck out WAY farther than normal so when I tightened them, I has to pop the tops off of 2 of the acorn nuts.
One tip I have for everyone who does this is to put a strip of duct tape over the bolts to hold them in place. It isn’t fun to remove some of the staples and cram your finger inside to push a bolt all the way through again.:o
I used a serated bread knife that was about 10 inches long. I used a permanent marker to draw a line where I was going to cut it and sawed away carefuly temporarily making sure that I was staying on my line. I cut the foam off of the top because it won’t work any other way. I then used a scissors to round the edges a little bit. I rounded the edges in the middle a little bit more to make it more comfy to hold.
If you’re asking if I used the staples that were on it when I took it apart, no. I used slightly longer staples because I had pulled a couple of the old ones out.
How nicely did the foam cut with the serrated knife? When I cut my KH Fusion saddle, the smooth edged knife I used was much cleaner than the serrated knife I used. The serrated was faster, but tore small chunks of foam off…
