    Forgot I have more pictures to share.

    Here is an example of a bottom bracket that needs replacement.

    When TwoWheels and I took it off, the bearings and lots of shards of metal flew everywhere. It was awesome.

    And here's the finished product, though without the rack and fenders.

    What was the solution to your chain drop issue?

    Didn't have the quick link closed fully so I could still take it off in case the length wasn't right. In hindsight, it should have been totally obvious that this would make the chain pop off. At least now I know for next time.

    "ok" is not "PRing both segments in one ride"

    That's over 80 gear inches. That might work for me on the moon, maybe.

    it'd be fine on Hains Pt if it's not windy, and Two Sisters is short. just go hard for 30 secs, wheeze, and repeat.

    I hadn't ridden Two Sisters westbound for a looong time until last week; I was amazed how steep it is going that way. At my best I'd keep it to 70gi. You're a beast for going after it at 80-something.

    Now that you've gotten me curious, my previous PR on that segment was fixed (46X16 or about 77 gear inches).
