The inside diameter of my seat post hole measures 28 mm. The closest sizes I see on this product are 27.2 and 29.2. Should I go larger or smaller?

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.

Don't guess what size you need. Worst case, you could destroy your frame by trying to insert a post that is 1 mm too large. Take out the old post (hopefully you have it.) Most seatpost shave the size stamped on them. If the numbers are hard to read, try shining a flashlight on from the side. If your post is not marked for size, use a vernier caliper to measure the size of the post, not the interior of the frame seat tube. This is an inexpensive tool that is helpful for many bicycle applications. I have one in my bike tool box.

27.2. There is expected to be a slight amount of play so that the post can slide in and out, but one mm too large will never fit. Note: this post doesn't have a seatpost collar, you have to buy that separately.

I have a similar bike (kid's bike from the 50s) and had to do some rigging. My seatpost is also not a standard size so I bought a 1/2" U bolt and used the flat metal piece with the 2 holes to attach to my seatpost. They send a lot of pieces so you should be able to get it to work. Since every bike is different, it's not really a one size fits all but, they do try to accommodate everyone with what they send. If you're not really mechanically minded I would ask a friend who is to give you a hand.

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.

I measure thFrom the center of one hole to the center of the other hole where the two hinges fit measures 5.75 inches. This seat is designed to fit a standard toilet. This product is of very good quality and has outlasted any other brand we have purchased in the past.

Unfortunately it didn't fit correctly on my seat post so I had to return it, so I don't really know....sorry about that.

Our BMX uses 25.4mm , Mongoose and Target Brand bike. The old seatpost that it replaced has a stamp on the bottom of it 25.4mm. Goodluck.

I apologize but since we do not carry the model we do not know the seat post size. The seat fits on any seat post with a 7/8" end (mount)

This seat post is very good quality. I believe the manufacturers recommendation is 25 lbs. that's about right. Very pleased with this product I bought the bag that goes with it and am happy with it as well

I ordered the elongated seat, my original seat measures 17 1/2 from front to back. Sounds like you have a standard toilet seat, if you order the standard I think you'd be fine. I think the measurements are a bit off in the ad. The mounting piece is about 3 inches wide and even counting that, my seat only measures 19 from mounting piece to the front. Hope this helps....I love it!!!

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

I tried to measure the "post" diameter, but I could not get to it from underneath and the saddle itself is attached with some sort of #3 Hex Cap that I could not seem to remove (like it is attached with red loctite?) The outer diameter of this hex-cap is 1.258", so the hole under that must be smaller (and apparently "threaded"? I will try to post some photos in a review momentarily.

I had a look at the pictures of the seat, but I am not really sure. Do you have an email address where I can send my email address to? Then you maybe can send me a picture of the connection on your seat and it would be easier for me to see if it would fit. Thanks!

I'm also 5'9" and wear a 31-32" in seam...I bought the 29" with 17" seat post and it fits me beyond perfectly...I would highly recommend spending some money on a new seat and pedals...

it will fit any size seat post as long as you have about 2+ inches of seat post to attach to. My gf's bike had a fairly small diameter post so i wrapped a few layers of velcro material inside then locked down the clamp.

It fits fine on my seat stay. The diameter of mine is 26.8mm and it stays in place.

Not sure... I'd look at the measurement etched into the bottom of you current seat post and make sure to order the same diameter... Or look up the specs on specialized website or have your LBS measure for you...

That is no problem at all. I am sitting here measuring and the inside diameter of the part that goes around the seat post and handlebar post is about 2 inches. One slight word of caution is that you need a little room between the bottom of the seat and bike frame to swing the catch mechanism. My wife is short and has the seat down low to the frame which makes it a little harder to get off but it is not that big of deal. Truly a well built piece of equipment.
