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.

Yes, I purchased a second seat for my girls bike. Her post was 1 1/8" in diameter and it fit perfectly. I should also add that the seat was super relaxing for her. It made for a very pleasant post ride experience.....if you know what I mean!?! lol

I believe the post is 27MM and every bike has a specific requirement so it is not a universal fit for any bike.

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

Yes, the seatpost diameter is correct. Your frame will accept a 30.9mm post. This is the 5" version, so make sure that you will be comfortable with it fully extended by measuring your current seat post at the highest setting you can ride with (usually for climbing). I have two of these ave they are great.

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 believe my posts are 3" as well. I used a rim of duct tape (torn to 1/2 the width) to widen the top of the post so these would fit tight. I did not drill holes in the posts , knowing I will replace these in 5 to 10 yrs. Hope that helps.

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 don't know exactly. but the bracket on this saddle is attaching to the seatpost of mine at 0.87". and the seatpost itself (wider part of it) is 1.2"

Your weight is good ..max..250..being 6.5 is questionable. .I'm 6.0 and use the 3 rd hole on seat pole...I think it may go to 5 holes..to be safe..u would be boarder line..the bike is nice if u can get it safely to u...un damaged..ha.

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.

I am a size 36 and I ordered a large which is conforable. I would go with the next size larger If it is a little big it will still be alright on the seat.

Not all bikes have the holes and i don't see an answer here that points out the 2 products you would want depending on your bike/personal preference: This will attach to the seat post and gives both prongs, pick one for your seat post tube diameter. http://www.amazon.com/dp/B000AO9PE8/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=JAO76YHZ6ZE0&coliid=I1D4K34Y7AXRKY or these, which you can attach to the tubes that go down to your wheel, put these where most of the nicer bikes have holes: http://www.amazon.com/gp/product/B000WYCJHQ/ref=s9_simh_gw_p468_d0_i7?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-3&pf_rd_r=0Q3HR5DB95D9X77HZB3Z&pf_rd_t=101&pf_rd_p=1688200382&pf_rd_i=507846 Again, these are made with varying sizes so measure the diameter of your tubes.

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.

Pull out your old seatpost and look at the lower portion of it, the size in "MM"...about 2 to 3 inches from the bottom usually. Unfortunately there are so many sizes of seatpost.

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
