I originally planned to ream out my 26.8 seatpost size to 27.2 on my GBW and MIT Atlantis so I could install a suspension seatpost.
But before I was able to purchase the reamer I was offered from a forum member to purchase his used 26.8 Thudbuster ST (3G) which is an older version of Cane Creeks Thudbuster. I am now in the process of replacing the worn out bushings and it fit my MIT Atlantis well.
I am now looking for another Cane Creek Thudbuster ST (3G) with 26.8 seatpost size to be installed on my GBW. So far no luck finding it on eBay.
Thanks :-)
