Sigh. It never ends.
I am pulling a mixed Tiagra-Sora off a lovely Colango Olympic Master frame (it deserves better I figure.) and I have hit a snag.
The rear brake cable housing that runs through the toptube (in below front, out top rear) is stuck, seized, jammed. The snag has probably arisen at the front entrance point where the housing is bent, the metal spirals exposed and rusting slightly.
I presume I am dealing with a single length of housing (I have seen set ups where there are two separate pieces on either end but this seems solid). But from neither end does it more than barely budge.
I really really really do not want to break it short leaving me nothing to grab to extract it.
Has anyone faced this problem before?
Can anyone suggest the best way(s) to attack it?
is there any worst case scenario for extracting housing stuck inside the top tube?
