I recently bought and am the proud new owner of a lovely DBR Apex ti frame. When I bought it I was fully aware that the down tube bottle bosses needed sorting, as the seller gave full disclosure so not complaints there. I now find myself with the dilemma of how to get the bosses out from the down tube without leaving the remainder rattling around in the frame forever.
To compound issues, the bosses have bolts in situ that won't come out as the bosses simply spin in the frame. After a chat with my lbs, they have said (they haven't seen the frame) that they can't help and would be interested in how I get on solving this issue, as the owner has a similar problem with one of his frames (albeit a rack mount on the rear of a scott with bosses welded, and he also doesn't want bits rattling around the seat stay for the rest of his life).
So my question is this, has anyone successfully managed to resolve this issue? If so, how did you do so without leaving bits of boss in the down tube, as the head and bb junction have such small holes there is no way a boss is coming through.
If it were possible, I would remove the bolts, but this is also a challenge as the bolt heads are bigger than the exposed boss, so I can't get anything around them to hold them still whilst I spin the bolts free.
If/when I get the bosses free, what can I do to replace the bosses, and hopefully in such a way that the repeat doesn't happen again, or at least attempt to fit new bosses so that I get use of the most useful bottle age mounts on the frame?
Help gratefully received/welcomed as I'm primed to get this build up and this is a sticking point to me cracking on, as I don't want to start building it up, then have to send it away.
Cheers
Ian
