Seven Duo, Maverick sus.
About twenty minutes into my last ride on this thing, it started creaking and
squeaking.
Stopped, dropped a little ProLink into the usual suspects, but no luck.
Got home about 3 hours later, turned it upside-down and noted that the bearing
cartridge's drive side was looking a little loose.
Went to tighten it by hand and it turned freely.
Took it apart and found the threads just stripped off. Not cross-threaded, just
sheared off.
Anybody have any experience replacing one of these things? Called Seven twice
today but couldn't get anybody in tech support to call me back.
I'm thinking (hoping...) that maybe the link that Seven uses is identical to the
one the Maverick uses - so maybe that would be another, possibly cheaper,
source.... and maybe even made of something a little more robust that whatever
metal the current one is.
Never been able to get definitive advice on how to secure either the BB
cartridge or those cheesy bearing bolts on this thing. Dealer says one thing,
one guy at Seven says another, another guy at Seven says yet another.
Right now, I'm thinking LocTite Red for the cartridge side of the BB, since
having it work loose seems tb a catastrophic event.... OTOH, maybe it didn't
work loose - maybe I just tore it loose and the Red would make it impossible do
disassemble without tearing the threads.
Also, this has been a little bit of a wake up call vis-a-vis materials. Back
when installed the Shimano BB my reaction to the plastic on the cup side was
negative - righteous indignation at the use of plastic and so-forth and
so-on.... Now I'm wishing the cartridge side was plastic too (instead of steel)
because then just the cartridge would have stripped and not the Maverick link.
