Accurate Readings in all Conditions
Shimano have extensively tested this new power meter system to ensure its accuracy and reliability in all weather conditions. The chainset is equipped with dual sided and internally hard-wired crank arm strain gauges, which provide a ±2% power measurement accuracy regardless of your pedalling position.

Easy to Maintain
The power meter is powered with a simple rechargeable battery for easy maintenance and can be updated wirelessly. As it is mounted to the crank arms 4-arm spider, you can change the chainrings without having to worry about affecting the power measurement.

Lighter and stiffer
Although the crank arms and spider arms are noticeably bigger to increase stiffness, the overall weight has dropped by 7g over the previous edition of Dura-Ace. The chainset has been adapted to work with disc brake road bikes that generally have 135mm rear hub spacing and shorter chainstays without the need to increase Q-factor thanks to its wider chainring spacing. This Compact version features a 50/34T chainring profile to offer an excellent rider tuned gear combination for varied conditions from flats to high mountains.

Shimano Dura Ace R9100-Power Meter chainset is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by weegrimpeur from Usual Shimano high quality. Needed a replacement DuraAce chainset and went for this as my 4iiii Precision had been playing up (crazy readings even after hard reset). It was much easier to install than some would suggest, and in my experience it gives pretty much identical data to the other power meters I've had (Stages, Assioma pedals, 4iii Precision, Tacx FluxS). In fact its a lot better than the Stages and Precision, which are left sided and both the Assiomas and this power chainset show I have a 48-52 L/R imbalance. All in all, I couldn't be more satisfied, its definitely the most reliable power meter I've had - all the others have given me problems with sudden dropouts or crazy readings or problems with water ingress. Data collected with my Tacx FluxS and this power meter are within about 3-5w, which is ideal as it makes my indoor and outdoor rides comparable. While the Shimano seemed a bit pricey on release, the current price which after all is for a chainset and power meter is not bad at all.

Rated 5 out of 5 by TheSaint1 from Perfect I have used many types of power meter over the years. I have now owned two of these meters for a year and they have both been faultless. Accurate and dual sided.

Rated 5 out of 5 by NexttoArchStanton from EXCELLENT I've had Garmin Vector, and Vector 2 over the years with so many problems, in the end I simply gave up with Garmin. After hearing about cold weather issues with Stages and problems with other makes I decided to go with a manufacturer that you could absolutely trust: Shimano. The period between their announced delivery and the actual one was probably nearer a year, however it has been well worth the wait. It simply works all the time and in all weather and I have had no glitches at any point; turn on the headset and it picks up power immediately. Its expensive, but so are various lots of Garmin Vector in my parts bin.

My Current drive chain/group set is Shimano ultegra, would this Dura Ace R9100-Power Meter chainset be compatible? or does the whole drive chain need to be Dura Ace? thanks

If you use 11 speed Ultegra, this chainset will be fine.

Does it transmit both ANT+ and Bluetooth simultaneously?

I'd like to connect this power meter to my cycling computer (ANT+) and the watch (Bluetooth) at the same time. Do you know if it's possible?
