I think, Luke, part of my response was colored by years of reading some
fellows -- whether here or other digital bike spaces -- disparage the
use of torque wrenches. But even though I didn't mean tough guy by my
use of "masculine," I failed when I put it in gender terms. I'm sorry.
But o'wise, sure, torque wrenches are another tool. And I can see how
there's virtue in having fewer tools. But since torque wrenches help
insure correct installation of parts, even with experienced hands, I
would think many hobbyists who are often less experienced would benefit
from that kind of accuracy.
Then again, I value accuracy.

Dave -
I guess my comment might have led you to believe that I have a tough
guy mechanic attitude which just isn’t the case. I have over-torqued
lockrings, but it’s easy to back off and the issue of over-torquing
isn’t dire like with over-torquing a threaded bb (I always use a
torque wrench for that).
Be that as it may, most (not all) bike mechanics I’ve met are not
tough guys looking to prove a point. My aim with my comment was to
share my opinion that most hobbyists spend too much time faffing with
tools and buying tools when that often isn’t needed/is overly expensive.

40Nm doesn’t seem crazy high in practice. I regularly use a torque
wrench to reach that cassette lockring value. And yet the ring is
typically quite easy to take off, with greased threads of course.
While most of us have a good feel for the needed tightness of
various bike threads, I often prefer a torque wrench since it gets
me closer to exact than hand feel might. For me, the higher the
required Nm value, like a lockring’s 40Nm, the more difficult it
can be to get exact (or close to) without a torque wrench.

think working without a torque wrench is somehow more masculine

I just installed one tonight by feel and noted the torque
recommended is 40Nm, that seems crazy high. I hope I never
have to remove one torqued to that number!

I just purchased the attached which can be had for
about $40-50.

Thanks everyone,
I managed to make time to sort it out (can't stand
not to have things riding shape) and the case is
closed for now.
It came off with a bit of a struggle. There were a
few bits of aluminum, which I cleaned off.
Everything looks fine, so I re-greased,
re-installed and took it a little easier on the
tightening. All seems good to ride.
Thanks all!

Agreed with Ian, when it comes to reinstalling
my procress is to give it a good extra tug
after the clattering "it's tight" sounds start
and call it a day. I've tried removing the
way-too-tight ones and it ain't pretty!

I'd be inclined to unscrew the lockring
now, while the grease is fresh. I've
always erred on the side of not tight
enough with lockrings because if they do
unscrew in use the only thing that has
happened for me is the shifting has gone
weird.
When you unscrew it, just be careful the
removal tool is firmly seated. If needed
and just to get it broken loose, you could
use a QR and a couple of washers to make
sure it can't slip and strip the female
splines on the lockring.

Hi all,
Asking for thoughts on a silly mistake
that I made last night.
I was in the process of replacing a
cassette (had not tried this myself
before) and I cranked way too hard on
a fairly long wrench and
over-tightened the lock ring. It dug
into the cassette and produced some
little shards. (I did grease the
threads, and don't think it's
cross-threaded, all was fine until the
END)
The question: does it make better
sense to try to fix this now (loosen
and re-tighten), or should I just save
this problem for an older, wiser me in
a year or two when I change the
cassette again?
I know I should get a torque wrench,
but . . .
THANKS!
Adam
