So I made a rookie mistake. I ended up ordering this ST, http://www.henryjames.com/columbus-3...t-tubes-3.html and I don't want to use it because I am going to make a custom seat sleeve for it and can't if there is a reducer glued into the end of the tube.

My question on this issue is if I can use a 28.6 ST in it's place and still be okay? My gut says yes, but thought I'd check with the masters.

Thank you in advance.
