Well that's pretty handy.
As for the chainring swap, I could definitely use my existing mid compact rings, I'm just not sure how complicated it is to do so. I'm pretty much married to the new 4 bolt standard (chainrings are out, ugh) unless I change the entire crank which will be tough (if I get something new, which I'm inclined to do after warrantying 4x Stages arms) as I'm still using a hollowtech 2/threaded BB. And I want to switch to speedplay this year so no pedals. And I want to keep using my HED Jets (6 and 9) so no powertap hub.
So yeah. If a used SRM can be relied upon, that could be an option. Or I can hunt around for a deal on Pioneer left side only, because in reality I'm buying two of whatever I get. DINKs for the win.

buying a used SRM is like buying a lease-return BMW; there are plenty of units still in service after 7, 10, 12 years, and used units retain value. that just isn't really the case (except with rare exception) for many other units.
key thing to look for is whether it is the new style battery (up to 2,100h life depending on model) or the older style. the latter may require you to send it in every 1-2 years unless you feel like soldering. there are particularly good deals to be had on the older style, though.
hell, wired units that are 10+ years old still have value. that says something.

I've used the Praxis and the Wheels Manufacturing versions. Have been happy with both. No creaking with either. Basically the same designs ... push adapters in, thread together like a real BB, ride bike.

The guy that built my frames is selling his 170mm wired SRM. Some older DA unit.

kind of a feeler, but i think i am going to be selling a bunch of zipp firecrest wheel sets -- 303, 404 and 808. tubular. i might have a set of 404 carbon clinchers for sale.
it's a little unexpected. if you were looking, i'd rather get them to a forum member than some random.

or you can just slap an aero bar on whatever you currently ride and realize most of the aero benefit.
frames are usually a bad investment ($ per aero watt savings), but is suspect you want the frame for other reason, not just an aero switch.

yeah, but then you can go all idiot and tape the whole bar.

I've had two carbon bars. One was great. (Ritchey Evolution) One was noticeably flexy. (FSA K-Wing) I currently have just aluminum bars now.

in fact, the bars are stiff enough that i realized the have highlighted flex in stems before.
(stiff enough for non-huge-sprinter-type rider, at least.)

i bought the wheels mfg one.
in my research i found far more reports of problems with the praxis version than with the wheels mfg one (pretty much none), and it's not like one company is huge and the other is small that you'd see a huge skew based on how many are out there.
there are different takes on whether it is smart to use a threaded PF-type adapter, though. it's just a gut feeling, but i kind of feel like it's not the best. i've never had squeaks/creaks from properly pressed/prepared PF cups, but that is just me and experience with generally higher-end frames.

I have 2 bikes with Wheels Mfg BB30 to GXP adapters. One is my winter bike and the other is my cross bike so both get the maximum amount of abuse and general immersion in filth. I've been using the adapters for 3-4 years and I think the one on the cross bike is just now dying. Or it might be the bearing going but I think it's wear on the bushings causing some groaning and shuddering under load. I have gotten my $25 worth many times over and will happily buy the same adapter again to replace it.
