Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them.

seatpost question.

I recently brought a carbon seat post which was 27.2mm dia and I thought I could force fit it in to my seat hole thingy so I measured it as 26.something close to 27mm, anyway after receiving it i have been measuring it again and again after I was not able to install it and realized it is only a 26mm. Damn old road bikes.

1. Do you think I should stretch the opening and force it down the tube, will that work?

2. DO you know who makes 26mm carbon tubes?

3. Why do the people of these companies make it so darn annoyingly hard for us to find parts?

Thanks.

Lost and confused.

To answer your questions one at a time;

1) NO! NO! NO! All you will stretch is the clamp. You don't think you could actually stretch a tube like this to make another one fit all the way inside, did you?
2) no, sorry.
3) To make us buy new stuff at regular intervals. Some of the old stuff lasts so long that some of us would never have to buy any new bike stuff if it were to be all standardized and perpetually compatible.

Are you sure it's exactly 26? Here's a list of sizes Thomson has to offer. You don't need a carbon seatpost.

You're looking at catastrophic failure and something up your butt in the immediate future if you tried...

26.8mm? Is your frame small? Some older bikes had proportional tubing and those run with 26.8mm seat post size in some cases.

Have that "seat hole" properly measured at your LBS. They have the tools for that. 26.0 is way different than "26 something".

oh sweet mercy, never force a seat post down. I did that to my old viscount with a hammer, got it 2 inches in, realized it wasnt going to make it, then couldnt get it out. i had to cut the post then saw it out of the frame with a hack saw blade, it took many , many hours as sheldon said:

"The three rules of hammering seatposts:
  1. Never install a seatpost with a hammer.
  2. Never, never install a seatpost with a hammer.
  3. Never, never, EVER install a seatpost with a hammer!"
yeah, i wish i read that first.

you probably don't need/wont find a 26.8mm carbon post, and if it is a vintage bike, a carbon post would be a one way ticket to tacky/lamesville

There's a very slight chance it could be burring on the inside diameter (ID) of the seat tube. If it's aluminium, try shaving it away with a steel blade. Also, because of the burrs, if you're measuring with a set of calipers, measure it with the ID side all the way down so the lip is in the recess of the caliper's forks to clear the burr, otherwise you'll get a smaller ID than it actually is.
