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 don't see why not. Remove your existing seat and measure the seat post. I believe it will fit any standard 7/8" or 1" post.

nickels55, Thank you for your interest in Silverback! The recommended size for your hole is 36" deep and a 16"-20" diameter. However, the goal also requires a 18" minimum rear clearance for the actuator. For the best understanding of the size and dimensions, please view the product manual, provided below: http://www.escaladesports.com/manual/silverback/B5402W-B5402F_2L719800.pdfHope this helps!

The inside diameter of the hole is approximately .725 inch, also there is a .425 in diameter post in the center of the .725 hole. hope this answered your question

Getting the exact measurements can be tricky. but a bit easier for taller inseams. I am 5'0'' ft and I can make it work with a 50 cm and that's pushing it. I looked at a bike tool for you and I would definitely go with the 54cm, because the bike seat can always be adjusted for a few inches. But if you feel its too small and you want something that might be really close to being to tall or uncomfortable go for the 58cm. Just remember comfort is a big deal when riding for miles. Hope it helps good luck.

Measure the width of your seat. Bought it and it was too small for my exercise bike.

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.

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

I clamped it to a 26.8 Schwinn Suburban seatpost. With its shape though, I think it's a little variable based on how much you screw it.

The clamp is made out of plastic as the others have said. There are liners in the jaws to protect the paint. They also have indicated that it will fit the seat post. I con't know about that one. It will most likely fit the seat tube that the seat post goes into. The seatpost itself? It will fit some for sure. A 27.2mm? I not as sure. I'd have to measure it to be sure. I've used it with the seat tube and it worked very well.

I believe my seat tube is 7/8" and it fit perfect as I believe that is standard size. It may fit slightly smaller or larger.

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

Most seat post appear to be of a standard size. I purchased this seat as a replacement for a 20 year old Trek bike. My daughter is very happy with the fit, comfort and quality.

Not sure what your height has to do with it. I'd say it's more the diameter of the posterior. The hole might actually be smaller than a normal seat -- I measure it at 11.5 x 7.5".

This is a standard size toilet seat. They measure them from the outside, and not the inside hole. I have one and it is as gorgeous and sturdy as the day it came last year!

It's best to measure your bike's post to be sure of the correct size. "Standard" could be a very relative term in the bike world. You can find a inches to mm conversion calculator on Google to make the conversion easier, if that helps.

For the handful of seats that I've used I hadn't noticed any different sizes in the rails but as this post clamps down on the rails I can't see why something like 6mm would be unreasonable (don't have a ruler or my bike handy right now; otherwise I could double check). I have it currently holding this saddle http://amzn.to/Se8Jes under my tush if that can give you any frame of reference. Knowing the size of my allen wrenches (which it seems I need all the time) the rails on that seat are in the range of 5-6mm.
