Seatpost sizing for Panasonic Sport 1000
I bought my friend and I each a Forte Precision seatpost at Performance today because they were really cheap, and we both wanted new ones anyways. We both have Panasonic Sport 1000's, and I used a caliper to measure the post which came to 26.85mm, so I bought 26.8mm posts. I can't get the new post in! Sheldon Brown wrote that the DX-2000 uses a 26.6mm post but that uses a totally different tubeset. Anyone know what size I need?

My friend finally got around to installing the 26.6 Kalloy seatpost...except it wouldn't fit. I'm going to try installing it on my bike sometime tonight, but the thing is my friend really needs a new post. Anyone have a clue? They're both Tange 900 tubesets.

you can also use these for accurate inside measurements of tubes:

you stick the "T" head down the tube, and tighten the dial, then remove and measure with a caliper, for EXTREMELY accurate inside measurements.

I just used my dial caliper...seems like the original seatpost is closer to 26 than 26.6. Oh well. I wonder why I originally measured 26.85...I used a digital caliper then!

Tubeset model isn't necessarily going to determine SP size.
Step 1: Take bike to shop.
Step 2: Ask them to measure it using a SP gauge (Devo hat looking thing, pic somewhere on Sheldon) or by just trying cheap posts.
Step 3: Buy the size you actually need.
To do it with calipers you really have to measure all the way down as far as they will reach, even then it's better to just do it right.
