spacer behind right cup in octolink bb?

I'm putting an ultegra road crank on a cross frame with a 68-109 bb.
The 39 ring brushes the chainstay. 68-118, the next size available,
puts the crank 7-8 mm right of the chain line.

Anyone have experience putting a 1 or 2 mm spacer behind the right
cup? If this leaves the left cup loose, is there a way to pack it out
a bit (ie between cup and cartridge?)

Thanks

Yes, add a wee spacer under the RH cup but remember it moves the left
arm inboard. OR get a rod or big socket and a hammer and 'modify' the
RH stay a wee bit if the material will allow it(steel or aluminum).

Thanks. I've got the bb in with a 1mm washer, and have the
clearance. Seems snug, but hasn't been ridden yet. Just wondered at
what point the left cup isn't snug enough on the cartridge. It has a
shoulder (agaisnt the shell) which prevents it snugging up to the
cartridge as much as it did without the washer.

The frame is aluminum. Ok to dent?

In some cases the bottom bracket comes with washers by default. The
manual says "mount washers A left and B and C right" - in my case
they're all on the left side by now. In most cases a washer of 1mm is
not a problem, as long as the *larger* part of the threads is still
inside the bottom bracket tube.

Try to avoid it - I wouldn't do it personally on aluminium frames. I
wouldn't even with a steel frame - there is always a way ;-)

Have fun ;-)

Yes as long as the 'dent' is round, not creased. Why you use a big
socket and hammer. Not a big deal, manufacturers do it all the time.

Yes, I used a spacer/ring from a Mavic wheel for that purpose on my Empella
CX bike.

Thanks all.

Still wondering at what point the cartridge starts moving around in
the left cup (or the right), and what you can do if it happens. Shim
the inside of the left cup? I still have a millimeter or two of room
for the crank and spindle to move right if I need more room, but don't
want the cartridge to begin clunking around between the cups.

Thx L
