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 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.

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

OD of the seat post determines size when ordering a new post. Don't know what the min/max sizes are, but I do know that you need to find the exact size for your bike... Close won't cut it.

First, Zaha, you need a conversion kit with a standard post. This is available at: Bicycle Seats - Dovetail Dist. 1409 Monarch LN. P.O. Box 305 Rexford MT 59930. SKU_ BSCIM-UNI-3-KIT. I also bought the seat there: BSJB-49233.I then bought a gel saddle pad at: www.serfas.com. This all made the seat tolerable.

I took a tape measure out and measured my seats ...the seat is 20 1/2 inches long by 6 inches thick by 22 inches across.The back is 22 inches high by 22 inches across and 5 inches thick..........THE back fits snug on my seats and the seat part is a little loose my seat could have been a few more inches long where its 20 1/2" it could have been 22"and it would not have hurt at all.My ADVISE ....get a tape measure out and give your seat a quick measure if your in these specs at all your good to go .

NO! You'll have to measure your post diameter with a caliper or take your old post to a bike shop to have it measured. Then order your new post accordingly.

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...

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.

If your seatpost is wider than 27.2 you could always use a shim and make it fit. (Check the numbers of your seatpost) This seatpost will not rise your seat since it is short (just 350mm long). So unless you use a 400mm seatpost full extended,it will be ok!. However, if your seatpost is long (400mm) and you use it at its full lenght, you may want a pair the seatpost with a bell memory foam seat to get the extra lenght you want. That's the best combination. I have it and it gives you plenty of comfort.

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 am not familiar with bicycles that use 28", sorry. You should check out their Nokian website. Other companies like Schwalbe may carry that size. Good luck. Ride more.

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

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

It is an adjustable clamp. I don't have time to measure the seat post at present but I believe I answered someone else that the clamp/seat are presently being used on a post that tapers to 7/8".

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.

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.
