Data is power.
Pioneer has forged ahead in the power meter market with the Shimano Ultegra 6800 Single Leg Power Meter Crank Arm. No longer confining the power meter to the intricate drive-side crank assembly, this meter is ideal for those riders looking to have power data measurement that also will not cost a college tuition.
The meter itself is housed in a sleek profile on the frame-side of the left crank arm to maintain the clean Ultegra aesthetic while capturing measurements at 12 points of rotation at 30-degree intervals, with 16 measurements taken at each point for accuracy. What this means for you is that you get industry standard +/-2% accuracy power data without the appearance of being obsessed with your training goals.
Zero Point Calibration with Active Temperature Memory Adjustment is also on-board to ensure power data accuracy while riding through varying temperatures on your adventures. The ANT+ compatibility also allows you to utilize most current cycling head units and apps, and it pairs well with Pioneer’s own cycling computer to gain access to the new HDPower Metrics and Cyclo Sphere program.

- Q & A
Does not fit speed concept 2018, rubs on
see title, could not install due to frame rub
- Familiarity: I've used it once or twice and have initial impressions
Installation - I'd rate 2 out 10 on difficulty scale. Less than 5 minutes if you have average skills.
Connection - Immediately recognized by Garmin 520.
Fit and finish - It's a Shimano crank arm so flawless from that standpoint. The Pioneer module is very cleanly installed and very low profile.
Accuracy - I don't have anything to compare with.
What I like - Uses a standard CR3020 battery so no hassles with charging. Very easy to open the battery compartment.
Happy with my purchase
- Familiarity: I've put it through the wringer
This is a great option for a power meter in my opinion. I'm particular about my pedals (Speedplay) and I have multiple wheelsets, so crank based seemed like a good bet for me. The Pioneer option is a trusted, established company. I have the left side crank arm only. This option was appealing to me because I am able to upgrade if I want more data (right side + computer) but I also have a great tool as it is. Is it essential? No. Is it helpful for my training. Absolutely.
Assembly was a little more difficult than I expected. Had my LBS install so I didn't mess anything up. Ended up needing a simple spacer (my LBS said Pioneer has great support with how to fix issue). I not had any issues at all once installed.
Solid entry level power with expansion
This Pioneer unit you see above is similar style to what Stages offers. I think the best part about this is that you have the ability to upgrade to a full dual arm power meter later on using the upgrade kit. Once you're upgraded, you have one of the few true dual leg left/right reading power meters on the market. Pioneer has plenty of experience in electronics, and I've had zero issues running mine for the past year. Would definitely recommend to anyone looking to get into power meters but either not sure if they'd use them, or not looking to spend (relatively speaking) a ton of money.
does this give a cadence measurement as well ? If not is there enough clearance for the Garmin cadence sensor ?
Will this unit work (have clearance) on a 2016 Fuji Transonic?
Is the PIONEER SHIMANO ULTEGRA 6800 SINGLE LEG POWER METER CRANK ARM compatible with Shimano 6770 set?
Hi Rob, since the spline is the same between those two generations, the left hand arm is compatible with the 6700 crank. There is only an aesthetic difference between the two models.
Let me know if I can help you out on one.
Will the left crank arm work with an Ultegra 6700 crankset?
Hey Ryan, technically, yes. The arm will mount to the spindle. I'll send an email to follow up.
Anybody at CC care to do the research and answer the questions posed here?
The answers may actually help sales.... Just sayn.
Does this require a magnet like I see in this video: https://www.youtube.com/watch?v=fNFCPBSlmwk
Do I need to bring it to a local dealer for firmware update if I don't have a compatible Pioneer cyclocomputer?
I know this question is rather old but i wondered the same thing coming off a stages power meter. Similar to the power tap rear wheel setup it just works. Not a whole lot to configure which i liked.
How does Pionier single leg power meter compares to Stages?
Is Pionier single leg power meter compatible with Garmin 810 ?
I just got a new bike and had a Stages installed. So many dropout issues that it's useless. Paired with a Garmin Edge 1000. I tried to work out the problems with Stages support. They had me doing stuff like disabling wifi, Bluetooth, mounting on the stem instead of the out front mount. Nothing worked. Did some research online. Guess what? Lots of others had similar problems. Frankly, I'd rather ride than help them to debug their product. Returning it ASAP and buying this - as my LBS says it "just works".
