I've got a old steel tourer with a very stuck seatpost. I've had success dissolving alloy seatposts out with caustic soda in the past but I'd rather not do it this time. The seatpost isn't anything fancy or fluted. What do you guys reckon to just sawing the top of the seatpost off and using one of these clamps designed for integrated seatposts on the bit left behind? Looks like I should be able to get enough adjustment out of one since the seatpost is currently only a couple of cm too low

even if you get the diameters right it will look fugly, if there is still a piece of it sticking out, you can try cutting at it lengthwise and pulling it out with a pair of big grip pliers.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
