Q-Rings on Ultegra Cranks

[Joelw135]

I plan on removing my 42T middle ring on my Ultegra triple crank and
replacing it with a 40t Q-Ring. Should I just do that or replace both
the middle and the outer? The outer is a 52t ring now, and I think
that the 50t Q-Ring would be the way to go. Is my idea correct?

Seems so close 1T or 2T probably would not make too much difference.
Not a good idea to mess with the small ring- I did; bad mistake: I had
a triple ring (about 32, 42, 52) but put shorter cranks on (55mm
instead of 170mm for a higher end- less Revolutions Per Minute) so I
had to eliminate the small ring.

Now I do not have the leverage or lower gear I had before. All I do
is keep as fast RPMs as I can, but changing yours seems the way to go
for very little risk of change. Changing just one ring might be a fit
& finish or appearance problem. Might be wise to change both rings-
your choice!

I was told by Rotor that the center ring would be no problem changing as
well as the outer, but the inner was not able to be changed. I am going
to change the center for sure, I just am not sure about the outer, that
depends on the cash at the time of purchase. I would like to give the
business to my LBS, even though his prices for the Q-Rings are $5.00 for
the 40T and $10.00 for the 50t. He said if he combines it with another
order I won't have to pay shipping.
