any tips on setting up a 6800 FD? For the life of me I cannot get it to not rub in the big-big combo. yes, I have the "converter" properly set. My bike has 40.5cm stays which I guess are the minimum shimano suggests, which I think is part of the problem.

6800 FD's are REALLY sensitive to cable tension. You may just need to mess around with the barrel adjuster a bunch to get it to be just right. Make adjustments in 1/4 to 1/8 turn increments.
Also: Be sure to double check that the support bolt is not pushing your derailleur out at a funny angle.

use the limit screw all the way in to mimic chain tension and set the bolt with the chain in the crosschain position so it doesn't rub. warning, it will now rub in big/small

i haven't noticed any crazy angle, but the support bolt is not something i've really looked at, I'll take a look tonight.
having it rub in the big/small sounds like a less than ideal situation.
i'm running the braze on derailleur (with a shimano clamp adapter)...am i reading this correctly that I want the back end of the cage angled slightly towards the inside of the bike?

Ideally you want it perfectly parallel with the small ring. The support bolt is critical. As you tighten it, it swings the cage outward. It only needs to touch the support plate. No tension is required. Also, I second Nutso's cable tension recommendation. It's really important to get all of the slack out.
Or you could just dump it for Di2 and be done with it.

so, i'm planning on getting a pwoermeter and was going to get with stages, but pioneer's offerings intrigue me and would be a similar price range to stages. anyone tried them? does the drive side upgrade kit offer any advantages to a single-leg non drive side meter? similarly, how does the pioneer non-drive side meter compare to the stages?

Now with all that said, there has never been a better time to buy a used SRM. You can get really good, clean used units with recent calibrations in the $600-$800 range today. If you were looking at a $500 new Stages versus a $700 used SRM, that's a no brainer. There's a sweet Si 170mm standard on ST right now that is going to make somebody happy.

I know it's silly, but I'm really averse to a wired unit and the idea of a used unit in general kind of worries me, to be honest.

This would be a bigger worry if the company you were buying a used unit from didn't offer good aftermarket support. SRM is awesome with that stuff.

I'm poking around where shovel said. Some interesting things for sale there. I eventually want to go to an Ant+ PM. I didn't think SRM would be possible but it might be. And it would be good because my wire on my red bike just died.

CDR, since I know you use Hollowgrams, I picked up an SRM Cannondale Spider last year for $550 - that included almost new Sram Force 11-speed chainrings. And it was the latest version of the SRM too. I found it on Craigslist in California. If you look enough, you're likely to find what you are looking for, it just may take a little back and forth, and a phone call, before you and the seller are comfortable doing a deal online via CL.

I need to sell some stuff first, raise some money to buy stuff.
I'd like to get a wireless SRM, I guess PC7 is realistic.

I wonder if you can buy just the cover for the laces, I have the Giro Empires and love them, Specialized shoes just don't fit me well.
