Stuck seat tube - any ideas?

"onyv...@gmail.com" <onyv...@gmail.com>: Apr 30 11:45AM -0700 Wanted to fold my NWT for storage in its carry bag, but found the seat post (mast? I'm not a gearhead!) is solidly stuck in the frame. It's been a few years since I last removed it, so not surprising I guess. I completely loosened the silver tightening ring and put penetrating oil and spray (Liquid Wrench) around the tube where it goes into the frame, hoping it would help. Still stuck. I've tried pounding on the bottom of the saddle with a mallet to try to dislodge the post and lift it up, but still no luck. Short of taking the bike into a LBS, do folks here have any tips?   Thanks. Lisa in PDX

Mike Fleming <mi...@warble.org>: Apr 30 12:05PM -0700 FWIW, I'm running into the same thing with my Tikit: I used to fly with it frequently, and then stopped some years ago. I'm sure I was not careful about re-greasing the seat post every time I flew, and now it's stuck. For me, I've had a bit more luck with the penetrating oil and I can actually twist it, so I'm certain I will get it out in the end.   But I wish I could go back in time and say "When you travel and take out/replace your seat post, alware remember to re-grease it!"   Mike       On Tue, Apr 30, 2024 at 11:45 AM onyv...@gmail.com <onyv...@gmail.com> wrote:

Ray Chong <xina...@gmail.com>: Apr 30 12:10PM -0700 Hi Lisa,   I'm assuming that you are referring to the seatpost, to which the saddle is attached? Does it look like the penetrating oil is seeping into the gap between the post and the frame? If so, apply liberally and let it soak for a day or two. (Use rags on the frame and under the bike to soak up spillage.) Before you try forcing out the post, you can try using a heat gun or hairdryer to heat the area on the outside of the frame to cause it to expand a little. Also, if you are able, insert a length of wood or metal rod in the saddle at the rails area to use as a lever and try to twist it side to side (but not in a position or with so much force that you damage the saddle).   Good luck!   -Ray

Walter Lapchynski <w...@bikefriday.com>: Apr 30 12:10PM -0700 To be fair, regardless of whether or not you're travelling with a bike or not, you should always make sure that there is lubrication, especially where dissimilar metals are involved (an aluminum seatpost in a steel seat tube). Stuck seat posts happen even on "normal bikes."   Here's the ultimate authority on dealing with this all too common issue: https://sheldonbrown.com/stuck-seatposts.html     -- Walter Lapchynski Sales Consultant | Information Services Assistant Green Gear Cycling dba Bike Friday direct line +1 541-234-5126

Ken Preston <ken...@gmail.com>: Apr 30 03:53PM -0500 I've had a few stuck over the years and penetrating oil almost always works. But it does take time to penetrate several inches. Keep lubricating liberally for several days up to a week. A good quality plumbers strap wrench will help. But only after the penetrating oil has been allowed to work.   Ken   On Apr 30, 2024, at 3:16 PM, John S. Allen <jsa...@bikexprt.com> wrote:      Oh!

Michael Jacoubowsky <Mi...@chainreaction.com>: Apr 30 02:12PM -0700 Also, regarding where to tap the post... best to do so from the side, near where it enters the frame, all around the circumference of the post. This may help to break up the corrosive bond (and will also help lubricant to seep in). If the seat post is to be replace anyway, remove the seat, and clamp the post in a vice and twist the frame. This will frequently remove the most-stubborn of seatposts, but generally at the expense of wrecking the seatpost.   Note that this is also something that generally doesn't happen when using a shim, because there's not as much surface to corrode together. People generally dislike having shims on Bike Fridays but my son and I have 10+ trips to France with ours and the shim has never been an issue.   Mike Jacoubowsky, Partner Chain Reaction Bicycles     -- LargePrefPlaceholder-XKUz1MEJBwkOM

Robert Wavrin <robert...@gmail.com>: Apr 30 04:48PM -0500 Lisa,   What has worked for me in the past is to disassemble the bottom bracket and put the penetrating oil into the seat tube (bike upside down of course). Let it sit for a day or two (or a week in my case). Make sure to wrap a rag around what is now the bottom of the seat tube to avoid oil all over the seat and floor when it makes its way out.   By doing this the oil has a much better chance of seeping through the tiny space between the seat post and seat tube and lubricating it. It's a pain to have to remove the bottom bracket but may help save a seat post.   Bob       On Tue, Apr 30, 2024 at 1:45 PM onyv...@gmail.com <onyv...@gmail.com> wrote:

"onyv...@gmail.com" <onyv...@gmail.com>: Apr 30 03:47PM -0700 Ah, good idea about putting a stick in the saddle rails to twist. Will try that. Put oil in a couple days ago.

"onyv...@gmail.com" <onyv...@gmail.com>: Apr 30 03:52PM -0700 Another good idea, thanks. I will try as a last resort. I'm heading out on vacation in a few days and am storing the bike to clear space for the house sitter.   FWIW I had lubed the seat post last time I'd taken it out, but that was a while ago and then Covid happened and I haven't ridden much at all the last three years. Live and learn (sometimes the hard way!)

"onyv...@gmail.com" <onyv...@gmail.com>: Apr 30 03:54PM -0700 Thanks Walter! Hope I don't have to resort to the hacksaw...
