Chump stumper – rear derailleur

[huskerdont]

Apologies that this is kinda long and involved; feel free to ignore if not your thing.

History:

1) Stupidly stated that 9-speed bike never needed adjusting.
2) Replaced OE rear derailleur with Sora. Worked okay ~1 year.
3) Installed replacement chain and cassette (SRAM 971, 11/28).
4) Broke chain on first ride. Lots of noise and a wreck; perhaps bent derailleur?
5) Bike shop replaced chain with random, unwrapped chain pulled out of the bin, assuring me it was a SRAM 951.
6) Installed replacement chain. Bike skipped in larger 3 or 4 cogs, no matter how adjusted. Sometimes it wanted to shift on its own, and sometimes it just jumped while staying on cog.
7) Discovered that random, out-of-bin chain had a sticky link. Thanks, LBS!
Purchased new SRAM 971 chain in actual original packaging … at a different shop.
9) No longer jumps, but still tries to shift or skip in larger cogs. Sora derailleur appears to have a lot of play in it–much more than Ultegra on other bike, but not sure what’s normal for Sora.
10) Installed 10-speed Tiagra derailleur that was a spare to another bike. Shifts beautifully, except…
11) I can get it to shift up to the largest cog (28), or the smallest cog (11), but not both. Limits from limiting screws are fine–the derailleur can move to all positions, it just doesn’t want to stay on the largest cog unless I adjust it so much that it won’t go to the smallest.

Opted for the smallest cog since this is a triple and I can go to the small ring if needed. Barring other ideas, next step is to eventually take to shop to see if mount on frame is bent (no derailleur hanger). Mount could have been bent in wreck, and it maybe does look possibly a little wonky.

Or I could just ride it since it’s now shifting like an (8-speed) dream.

It’s better, but it wants to slip off the larger cog under load so it’s set to work with the bottom 8 cogs instead. Will need to find a good quality 9-speed mech for it to work on all cogs. Since it’s a triple, it’s no big deal, and I have other bikes for climbing expeditions anyway.

More important question: Did Vicegrip let you ride his horse?

The man has many fine steeds, but the weather was mucky and it would have been poor form.

The title to my ride on Strava had been “Went to see a man about a horse,” an old blues euphemism that I meant to be a play on words.

Judd is just being Judd and confusing people for fun.
