Installing a Bicycle Seat Post from Performance Bicycle
I’m Jean with performance bicycles I’m
one of our spin-doctors and I’m here
today to show you how to install a seat
post first thing we want to do before
we’re going to before we take the seat
post out is to measure how high the seat
post is do that but taking a standard
tape measure and starting at the middle
of your bottom bracket measure up the
seat tube all the way at the top of the
seat so measurement would be right to
here write that down somewhere so you
don’t forget the height measurement of
it now you’re ready to take your old
seat post off take a hex wrench of the
correct size this one happens to be a
four millimeter X hex wrench and slowly
loosen the bolt on the seat clamp and
pull your old pull the old seat post out
now after you pull your old seat post
out take a look at the seat post there’s
gonna be a measurement down here that’s
inscribed on the seat post this this
measurement is really important to make
sure you get your replacement seat posts
the same size this one happens to be a
twenty-seven point two millimeter seat
post so we’re gonna install another
twenty seven point two millimeter seat
post so you post come in two tenths of a
millimeter increments so it’s real
important to get the right size the seat
post that’s too small
well will won’t you won’t be able to
tighten it correctly inside the inside
the bike and the seat post is too big
you’re not going to be able to insert it
in there now before you put the new seat
post in you need to lubricate the the
seat tube itself on the bike or you can
lubricate the seat post either way you
can do that by using a little bit of
grease on your finger you put it inside
the seat post or inside the seat tube
and on the seat post itself now if the
seat post is carbon fiber you need
you use a carbon fiber grip type paste
instead of grease the carbon fiber grip
will help the will help hold the
seatpost in place with and not not have
to use as much clamping power on your
clamp when you install the new seat post
just slide it back down in then tighten
seat post clamp down to the correct
torque spec for that particular clamp on
this clamp it’s 5 Newton meters now
after you install the saddle be sure to
raise the seat post or lower back to
your original saddle height that you
measured at the beginning and that’s how
easy it is to install a seat post if you
have any questions give us a call it’s
been doctor services or come by and
visit us at your local performance bike

A bicycle seat post, eastern, saddlepole, satin or saddle pin is basically a metal tube extending upward from the back of the bike to the seat. The distance from the seat to the back of the bike is also adjustable, and most places will have a size that corresponds to a particular size and brand of bike that’s being used. Most seats are adjustable to accommodate bikes with a seat tube length as long as 160mm. Most seats are also adjustable in height as well, but you may need to make sure that the seat is tall enough for your height. A bicycle seat post may either be detachable, which means that you just put it up and take it off, or it may be fixed, which means that you have to attach it permanently to the seat using some type of bolt or screws.
Seat posts are typically installed by hand, but many manufacturers of bicycles are now making it much easier and faster to do so. You should have a level surface, preferably an old board deck or the sidewalk, that is flat and level when you’re installing a seat post, especially one that attaches to the seat. When you’re using the correct type of seat post, it shouldn’t take you more than a minute.
You should use a screwdriver to remove the seat post from the seat tube, as some people like to do it by hand, but if you’re not sure what you’re doing then you may want to leave it out. You should remove the bottom bracket, or seatstay if it’s there, and the top bracket, which attaches to the top tube on the back of the bike. Then you can lift the seat post up and over to the front of the bike, using a wrench the wrench just below the seat, just above the dropouts, and slide it over to one side or the other of the seat. If you find that the seat post is already too low, simply remove it a few millimeters, since it shouldn’t be touching the seat tube or chainstay yet.
Now you can easily slide the post down into place, which should hold it in place once it’s in place properly. You should be careful when you are sliding it because you don’t want to damage your bike’s chain or rear derailleur, and you should keep your foot in the crank to avoid rubbing against it.
You can’t just simply install the seat post into place, as the lower portion of it needs to be screwed into the seat to get the post in position. You should put the post in a secure position by using some sort of clamp or clamps.
It’s probably best to take the seat post and seat into your local bicycle parts store for you to determine exactly where you can drill holes for the bolts that attach the post to your seat. The holes that are drilled into the seat should be placed where they match the corresponding holes in the seat, and not just in the middle of the seat where the seat would normally be. To do this, you should look under the seat and make sure that there isn’t too much space between the holes so that you don’t over-drill and cause more problems than you already have.
