possible to cut a seat post??

hey, just curious if you can shear a few inches, maybe 1.5 off a seat post.....curious if it will weaken it at all or if its unsafe....

this comes from my thought that if i cut and inch and maybe a half off my seatpost, i could still get the height needed for riding trails with my inseam height where it needs to be, but this way i could lower it more so i get a little more standover height like on a dj frame, so when i do lite freeriding on my bike, itd be that little bit easier/more comfortable on the boys *wink*...

thx

Shear away, just be sure to leave about 2" extra (or whatever length is past the "minimum insert" mark) so you don't break the seat tube. Also if you're not finished growing allow for that too.

Another option: I have two seats/seatposts for my Enduro, one short and one long, and I simply swap them for whatever riding I'm going to be doing. The frame design doesn't give enough adjustment to do everything with a longer post.

Knock your self out. Presuming that you want to cut the area indicated by the red box and that the mark at A is your min insertion mark you need to mentally take into account that your new min insertion mark is now at position B . This mark moves up the post equal to what you cut off.



Pardon the crudely rendered image it was a quicky

you can, but you need to leave enough over the required amount.

Hey Enduro, have you checked out these posts: http://www.titec.com/items.asp?deptid=4&itemid=135

I was considering getting one for my Enduro SX. Probably will when I get some spare change.

Also make sure you deburr and chamfer the edge after the cut. It can be nasty later on if you don't.

That could be cut too, but with great care. For that use a dremel cutoff wheel. Then dress the end with some epoxy or something of the sort.
But yes, it is a much different beast.

Use a pipe cutter tool. Hacksaw method never comes out right. A cutoff wheel on an angle grinder would work if you've got a steady hand. File the end smooth when you're done.
