seatpost size and sealed seat tube in 89 RB-2?

[Steve Litvin]

Hi All,

Two questions:

1) Anyone know what the seatpost size is for a 89 Rb-2?  I've actually owned it since 91 or so but its been sitting for a while.  I thought it was 27.2, but I'm getting the feeling its a 27.0 or 26.8

2) Did this generation of Bridgestones come with sealed seat tubes?  I was cleaning up the bike and for the first time noticed there seems to be a sealed plug 10 inches or so down the seat tube.  At first I thought maybe I was forgetting I snapped a post off in it but it seems to be sealed, like the tool to remove a traditional head set race.

Thanks!

Steve

If you don't have any luck getting an answer here, there is a  related list with lots of knowledgeable folks...some of whom are in both groups

And Sheldon Brown site has some scanned bridgestone catalogs going back to 88 or so...I know this because my partner Terry Scott did some of the scans...

Good luck!
