Very interested to hear feedback on this after you use it a bit. This is a very interesting time for power meter development; we are about to hit a point where this data is very accurate, portable, and affordable (even for multiple bikes) for the masses.

Seriously, I have a couple, from old team kits. One Giordana, one Castelli. Both are race fit, otherwise they use different approaches. The Giordana vest is mesh in the back and has pockets. The Castelli vest is unvented and doesn't have pockets, just zippers to allow access to your jersey pockets. If you're going to be wearing it at temps over 50 degrees, mesh back is probably the way to go.

The 2nd item is if the cranks have a recessed area for the pedals they want you to use a washer. These cranks are the Look 795 one piece and have triangular flat plates so you can adjust crank length. I chose not to use the washers and think the plates will be fine.
The software requires you plug in BOTH pedals via USB. You can electronically read the pedal serial number ANT+ ID etc. You can program the light (to stay on in use or not) and right/left correction. Also firmware updates are done through the software and you can shut down the pedals for storage so they are not broadcasting when moved on the shelf. They won't turn on again until plugged in if you electronically shut them down. Otherwise, they come to life on movement.
These replace the DuraAce pedals. They have very smooth low friction bearings. These pedals are light - 156g each and this is a great design. Obviously accuracy matters, precision more and we won't have that data till later. But very well made and designed and the Italians were responsive to my support issues in ordering (cc shutting down for fraud, Windows 10 Edge browser issues).

bePro installation feedback (they have a video). They use a locknut on the pedal shaft so you can align with the sensor. The locknut is about 3 threads thick and is to be tightened 35-40nm and they give you a big cone wrench thin tool to do it. It is not a torque wrench and I didn't measure the size (guess I should) but guessing 35-40nm could be tough and as it is thin I was very careful not to over tighten and strip the threads. I'd expect they have spares, but would be a pain to get them. So...if anything the pedals are not tight enough, we shall see.

Replaced the cable, replaced the cassette with one with fewer than 100 miles on it, and doused the shifter numerous times with WD-40. No joy. I'm going to finish that can of WD-40 tomorrow. If that doesn't work, the 6600 shifters come off a bike I'm not riding and go on the rain bike. I hate to get rid of those shifters.

Thanks, [MENTION=212062]milmo[/MENTION]. The fix turned out to be the RD hangar. It had apparently been bent and straightened once too often, and wouldn't hold the adjustment. A new one fixed the issue. Replacing the 7800 shifters with 6600s didn't fix it, but the 6600s are staying on because I haven't crashed them yet.

I just ordered a weight for the sole purpose of statically calibrating my power meter. Pretty insane. I mean, I guess I can theoretically use it while doing exercises as well, but that's definitely not the primary reason I bought it.

the training thread is a good example of that.
if you do use it, be careful--if a calibrated weight gets rough handling, you can damage the very thing you paid for (e.g., chipping a few grams off of whatever surface). maybe not a huge deal but it runs counter to what you are hoping to achieve.
10 kilos, at least? hoping you went for 20+.

just some random one which had decent reviews, supposedly "35" lbs. the plan is to use a lab at work to find out how much it actually weighs, so i don't really care how accurate the claimed weight is. i dont think i need to be careful with it either given i can always re-measure the weight before each test, no?

50 degrees, at night and it's cool/dry California air for the most part. I assure you it feels cold at 25+ mph with no sun to warm you up and I grew up in Chicago so I know cold. I've seen plenty of guys in team kit wearing them around here with temps in the 50's. But yeah, I'm talking about the lightweight ones and not the kind rated for freezing temps.

I didn't read past the installation section. But it gives believable numbers 1st min. I have to get the new tire on the PT to compare.

As per my long winded post on the CTS thread, as a believer that training power and work should vary based on how the athlete is doing, I'm digging this.
Like SPO2 and HR it is portable to other sports (running, rowing).

this comment from someone who has been using them a while was interesting (or scary, depending on your POV):
curious for what you find, esp as the author of that site tends to do testing that focuses more on what triathletes want vs competitive cyclists (e.g., he seems to care mainly about average power over longer durations and not response to changes in power and cadence over shorter durations based on reading years of his reviews). that he is noting the settling issue is, well, noteworthy for that reason.

there's another monitor that does non-invasive measurements of lactate; the variance has shown to be quite substantial based on where it is placed.
