What size seat post does it fit??

It fits perfectly on my 1.25" (31.75mm) OD post. If you have a smaller post then you have to use the shims come with it. It is not strong as direct mounting on the post.

I put the calipers on my bike post and it shows it to be one and one-sixteenth inches (1-1/16"); I had to use two of the three plastic shims that come with it to make the rack fit properly on the post. Without taking the rack off to measure the opening without any shims in place, it appears it should accommodate a post upwards of 1-1/4" thick. With all three shims in place it should probably fit a post as small as 1", or possibly just a little less. The three shims included should allow it to fit about any standard post, I would think, but not sure what acceptable standard post sizes really are.

The rack comes with several plastic shims so it should fit most about any size seat post. But in my case, I chose to use layers of bicycle tire inner tubes instead of the provided shims. Force of habit, plus I had a bad experience with plastic shims when I installed this same rack on a Dahon folding bike. No scientific instruments required in installation. :-D

The outer diameter of my seat post is 1". I had to use one of the spacers that it comes with, plus a more pliable layer of rubber that I cut from a rubber pad (that you can find in the plumbing section at your hardware store) and it fits quite snug. The spacers it comes with could be of higher quality but tough complain given the price.

depends on your seat post size. Check this link against your bike year to get the right size. This camp is for a 7/8" inside dia..http://sheldonbrown.com/seatpost-sizes-m-z.html#r

It fits a regular seat pole. If the seat pole is a regular one, it will fit. Don,t know what a specialized bike seat post looks like. P.S. the seat may say pillow, but it is very hard. I have on on my exercise bike and just used it last night and it is hard !

Sorry to hear about your theft - seems like nothing is sacred anymore. The clamp for post tightens up to hold it on to frame & also adjusts onto seat. My post is approximately 1" wide. A bike shop can help you. Good luck. Carol

In my opinion you need to make sure you get the exact size you need, I don't know what you used to measure but you should try to look up your bike on a sight such as bike-pedia that will give you the exact sizes and stats. for your bike. That being said 27.2 is one of if not the most used seat post sizes along with 25.4 so that might be what you need, but seat post sizes are in increments of 2mm and if you do not buy the correct size it is more trouble than taking the time to get it exact.

Once wrapped around the seat stem, which is already at a 14-18 degree angle, or 'slant,' the seat extend well over it. It protrudes 2/3-4" inches from the center of my Campagnolo Titanium seat post. Exactly. My post is 1" in diameter. I hope this helps.

I don't think it will fit. My posts are exactly 4" and the fitting is very snug.

Best I remember there are two mounts. One small one that'll fit the seat stay, and one that will fit the most common size round seat post. Just one mount, but two different size rings. It also comes with the rubber strips to make a small post larger and snugly hold the ring.

I attached it to a different bench and it works fine, the post measures 2 inches by 2 inches.

The only way to know what size it is will be to measure from one side to the other (diameter) across the very middle. No way to know from a picture. My guess would be an 18' or 24'. Mine is a 28' and there aren't enough posts to be that big. Measure it and measure it again lol.

Most seatposts are 350mm in length, but some longer ones are available, at lengths up to 400mm. You should be careful with longer seatposts, however, as they can stress the frame and possibly cause it to crack.

Scroll down to technical details... product dimension... 11" x 8.8 "..... will it fit your seat ? Measure your seat !

I checked the diameter of both the units I bought and it looks as if 1" is the max diameter of the post clamp.This would not fit my seat post but the rear frame wheel support.Hope this helps... Please note that the most recent one purchased only had the large size clamp and came with two dead batteries. Perhaps this was a customer return.

As long as You have the post and the knuckle that hold the seat sidebars, it will fit. It really is a great seat. My wife loves it, as we do 20 to 30 miles at a time.

I measured mine and it will probably fit 29" tip to bottom and 20" side to side. I have a Grayco 22lb seat and it fits. Probably not much help.
