FWIW I've gotten an 11-32 to work with both 105 and Ultegra 5800/6800 short cage RDs. Sizing the chain for the 32t makes the 34x11/12 unusable but those aren't combos you'd use regularly anyways

I'm a Quarq guy, but if you can use road cleats and don't need a lot of float, pedals would be the way to go.

Adding a new rear der, chain and cassette to the equation starts to eat into the lower price on the wheel. This worked into my purchase of easily swapped pedals as they were all I needed.
In any case, make good use of the Powertap. It brings cycle training up a few notches.

The 11-32 fits with my Ultegra Di2 derailleur. The bike came with 11-28. The gap between the upper pulley and the 32 cog is very small, appearing to be too tight to work. But it shifts fine, with no problems.
I carefully checked the chain length (It was long enough already) :
In the middle cog on the back, shift to the big chainring. Then lift the rear wheel, turn the crank by hand and "carefully" shift to the largest cog. You want at least a small jog on the chain between the pulleys -- not stretched completely straight. Then test it again on a parking lot at low speeds and low pedal force.
(The fit probably depends on the derailleur hanger's length, I suppose. It might not work on every bike.)

Sorry to resurrect an old thread, but my situation is similar to firebird584's and the responses covered virtually all my questions. For the same reasons, I'm considering a PowerTap G3. Mine is a 2012 Tarmac Expert with Fulcrum Racing 4 wheels. I don't race, so I don't need separate training/racing sets, but I'm not sure it's worth rebuilding a 6 year old Fulcrum around a G3 hub. Aside from the 75 gram weight penalty (1725 Fulcrum Vs 1800 DT Swiss), is there any reason I shouldn't just buy the pre-built DT Swiss R460s for $550?
Thanks, Nick

I went with the Assioma Duo pedals myself. Simple to install and simple to swap to another bike, rechargeable and the charge lasts a long time. Compatible with just about every bike out there. When it comes to crank arms, chainrings, add-ons, it just seemed like there would be too many issues with my older bike, and I like my current wheels. Just reading through all the comments on this thread about all of the other types of meters makes me think I made the right choice. There are just too many things to take into account with the other systems. Also, these pedals connected to everything without any problem, and included cadence too. The only thing that would make a difference is if you use a different type of cleat, and you are completely wedded to them. Keo only at this point.
Yes, absolutely. Except that it does not do well with Wahoo head units. Wahoo's fault not Favero's. I love my pedals though.
Just today compared with my Kickr, and every interval was within 1-2 watts.

Hey, my thread's back! Quick update on my end, the G3 I ordered built into the cheap DT Swiss wheels have finally shipped! Apparently there has been a hold up at PowerTap, if you're looking to take advantage of the PowerTap price drops, I recommend buying as soon as possible.

Yes, we've had that discussion on the DCR comments page. It works fine with a Yahoo except for Avg watts. I would like to turn on 3s averaging instead of pure watts to keep it a little more consistent, but that matters more on a stationary setup anyway. When I'm riding all out outdoors I'm not looking at my computer to see how many watts I'm putting out.
edit: ah, I think that I see you two in the review thread on DCR. I haven't read all of the comments, so to clarify, you're talking about how the head unit displays average power and possibly crank arm length? I ride 172.5s, so not an issue if that hasn't been addressed on Wahoo's part, yet. On the average power thing, I take it that it's a matter of counting zeros or not counting zeros? If that's all that it is, that's probably fine - I doubt that average power is a field that I'd display, anyway.

Good luck with them. It's always a good thing to have a backup wheelset in case you've got problems. Now you have that and can switch between the trainer and the road easier.

I have been pouring over this thread and doing some research and at this point I am seriously thinking of getting the Assioma Pedals. Might as well the duo set I hope it is a good move. I saw one serous video that compared PM and seems that accuracy for pedal power meters may not be quite on par with the best. If is was consistent probably going to have to live with it because the other options are too complicate.
I know I do not want a hub PW the only other option is the Shimano left crank option and that could be equal or better. I hope more chime in on this who have PM and experience with them.

I'm thinking of getting both the Assioma Duo and a Bolt in the next month. In what way don't they work well together? I've seen mention of BT being a little wonky, but I don't see why I'd use that over ANT+.

I'm surprised at this point that Wahoo hasn't fixed it yet. It can't be hard. It is only the display on the unit itself that is inaccurate, when downloaded to an app everything is fine. Crank arm length is handled in the Assioma app if it is not available elsewhere. I've been using them for 2 months now and have been pretty happy so far. Mostly indoors though, since the crappy weather just doesn't want to let up.

No, nothing to do with the zeros. At least with power, and actually cadence too. If I maintain 90 cadence religiously, and say 170 watts for an interval, the downloaded file shows accurately, but the avg is never correct on the display.

Not a huge issue, and hence still waiting, or would have switched back to Garmin earlier itself.

What's wrong with cadence? Is this another average (per segment or per ride) that doesn't display properly or does your current (smoothed) cadence not display properly?

Avg per lap/ride that does not show correctly on the live display, but is fine when the file is uploaded.

Okay, thanks - so it's the same Avg issue as with power. Yeah, neither of those metrics are terribly important to me, and I don't think that I'd have that data displayed. I can see how the Avg Power might be helpful for interval training, but I tend to target the now and let the average work itself out.

Average cadence doesn't interest me, so I don't know if it is an issue. Maybe I'll check with Wahoo if they have any update on this.

It will end up costing virtually the same to have it built into your current wheel, so, might as well get a second rear wheel or full wheelset. Keep in mind too that the DT Swiss R460s are tubeless ready so if you upgraded your tires to tubeless that would likely make up for the 75 gram weight penalty.
Also, on another note, NICE BIKE! GO TARMAC EXPERTS!

I'm intrigued by the tubeless option, but it's a bit confusing in the absence of a standard. What route do you plan to take?
