Suggestions?? I think I had this problem before and tried to tighten the circular return spring and itís been several years, all I recall is it ended up not working and I got very frustrated.

Help!

If I remember correctly, there's an E clip on the back side of the "B" pivot. Should be a coil spring with the ends bent into 2 nubs that seat into holes.. take the clip off and inspect the spring,, make sure the nubs are still on it. Make sure the holes they sit in haven't sheered off. Or the "B" pivot could just need cleaning and grease.
Be careful after the clip is removed the spring is under tension and could come apart.
EDIT: Now that I look at the pic a little closer. The attachment bolt and surrounding area looks a bit beat up. You didn't drop it recently did you?

This! I’m betting broken-off “nub,” favorite failure mode of coil springs.

No recent drop. Will try to lube this better and check chain life, as well as ensure spring nubs in position. Will avoid taking spring out as thatís what I messed up several years ago, but if problem persists I may have to.

I have nothing to add other than to observe that that chain looks too loose.

Not sending it across the room is 90% of the battle. :)

It has crossed my mind....

I have considered getting a whole new groupset for the Habanero, but an hoping to keep current version going for another 1-2 years and plan to get the next-generation Shimano when itís out.

Speaking of RDs, I've been running a Dura-Ace 7800 rear derailleur and downtube shifters all year on the Trek, but I'm wanting some lower gearing - at least 32T in the back, preferably 34T. I know that some people have run larger than 28T in the back on those derailleurs, but I'm already exceeding the capacity as it is with the short cage. Long cage 7800 is prohibitively expensive and wont' give me the max cog I want anyways.

Part of me is really wanting an XTR RD-MD980, partly because that smoked grey finish is so cool, and also because it's a rapid rise model which adds some interesting character.

However, that stupid voice of reason is telling me to spend less than half the money on a brand new 105 RD-5701-GS. I'd probably be happier with the 105 but compared to the XTR it's just so uncool.

If I was down at the shop, I'd take it off the bike and throw in the the parts washer. At home, I'd degrease with soapy water/solvent and re-lube. Or hit it with some 1-Step.

Got out for a good ride. While I did not traverse and frozen lakes, I did ride on a mostly frozen creek. It was all very Instagramable.

Well I'll have to wait a little longer. Someone bought the only good one on eBay :rolleyes:

There are times when looking at the relative cost is pretty sensible and there are times when looking at the absolute cost differential is much better. It's like when people try to rag on expensive socks, "are your $15 socks 10 times better than my $1.50 socks?" Pfft - I don't know if they're 10 times better, but they're certainly $13.50 better." In this instance, I think it's more sensible for you to look at the absolute rather than relative price difference - in the grand scheme of things, it's not that much, 'specially when you factor life expectancy and usage.

Consider a Wolf Tooth or similar RD hanger extender?

I believe I have one that's been collecting dust that someone gave me many months ago. Still sad to see the old TimeX retired.

Not a bad way of looking at things. I know that I'll only think about the purchase price at the POS, once I've got it in-hand the pain will already have passed.

I am trying to get away from buying everything used though, which complicates things. There's no way I'm paying the NOS prices for one of those XTRs, if I'm spending that much money I'll just get 11s Campagnolo ;)

I may or may not already be exceeding the total capacity of the RD by 5 teeth :innocent:

I do need to pick up another goat link for the MTB at some point though :thumb:
