What Size Post for a '87 Bianchi Brava

Hi there!

first off - apologies for dragging up a thread from the depths of the internet!

i've just managed to finish extracting a very VERY stuck seatpost from an '87 bianchi brava, and was wondering if anyone could tell me the correct size post i need to replace it with?

if the frame stickers are to be believed, it's an italian made frame with columbus tubing.

thanks!

Chris.

OP, I broke this out to its own thread and moved it to a forum that will get you more exposure and hopefully more help. Good luck with the seat post.

The answer is that is what digital calipers are for. You can buy a set for the $10 to $15 range. Then you can measure and will know what you need. You can also use them for years to come to answer similar questions. If you go to Sheldon's site he does post some seat post sizes. Roger

It should be 27.2 if it is one of the Bianchi Formula tubed bikes .

My Brava is '87 (so said BG). IIRC, the seatpost was some odd-ish size, certainly not 27.2. After measuring the inner diameter I ordered one from some guy online and it went in loose so I put a caliper to it and it measured smaller than the indicated size so the seller sent me another one which went in better. I say all this only because it took me a while to get the right one. I'll have to measure it.

26.6 but you have the Tange tubed US market version. The OP says his is Columbus.

26.6 out to 27.2 that seems like a lot of shim to me.

Ah. That's very different. Same name, different bike. bigshape, don't listen to me. Don't shim unless you can't find any other way to do it! Better to get the right post.

sorry, it's a 26.8 post so only .4 difference...
beer can shim has sorted it for the time being until I find a suitable replacement. like I said, it's just a hack / pub bike built from mostly spares and free parts.
had a quick spin on it last night, rides really nice!
