    4iiii Precision 105 R7000 Powermeter is rated 4.8 out of 5 by 11.
    Rated 5 out of 5 by Jordancbr from Just very good. Good price, working perfect.Change my training for different level.Recommend.

    Rated 5 out of 5 by PaulineW from Can’t fault I know that a double sided PM is considered better (for loads of reasons, including identifying power imbalances between legs) but I’m not a tour rider, I don’t have wonky legs and I’m not all that bothered about having the best / most fancypants kit on a group ride so to be honest, the perceived “limitations” really don’t matter to me... accurate? Couldn’t tell you as can’t test it, but it is consistent and a great tool and I think a necessary to support effective (indoor) training and to help with pacing on a ride when outside, but when you’re out on a ride, you just dig as deep as you can to keep up / blast up them pesky hills and the numbers are what they are. Has given me a more rounded view of my performance though, and as mentioned, gives a number to aim for / push past when interval training.

    Rated 5 out of 5 by SJP65 from Reliable power info at your fingertips Easy to install standard Shimano crank. Easy to fit battery cover which seems robust and stays in place! Once synched my Garmin finds the power meter every time with no further rider intervention required. Can download the 4iiii app which allows the power meter to be updated and keep a check on battery life so it doesn't die on that one major ride.

    Rated 5 out of 5 by Maria46 from Power to the people Easy to install, looks like the original R7000 left crankarm and easy to pair with a Wahoo Elemnt Bolt. The only issue I have is battery drain. The first two weeks the battery droped fast but after two months the draining speed has slowed down. I disconnect the 4iiii app with the Chipolo Finder feature after I have read comments that it causes battery drain (never got it to work, though. The 4iiii got located in London every time!). I have a Canyon Ultimate CF SL disc 7.0 XS 2019 and have a spacer to get enough clearance between the 4iiii crank arm and frame. I am using a Wheels Manufacturing Crank Spindle Spacer - 24mm, 1mm.

    Q & A

    Is this compatible with Shimano 105 5700 (older version)?

    I’ve got a bike from around 2014. Has Shimano 105 but 5700 version. If I just swap the crank arm is this compatible with this newer R7000 version?
    Asked by: fleckers
    Will answer my own question in case useful to others. Ended up buying it anyway. My bike is from 2014 and had 5700 (10 speed) version of 105 gear. Bought the 7000 crank arm with 4iiii power meter. No problem fitting and works fine. Only issue is minor cosmetic difference which I’ve shown in attached photos (new crank arm fitted and old one held next to it). Personally I doubt if anyone would ever notice or care!

    Hi, how do I know what size will fit my bike? Where can I check it?

    If your bike already has a shimano hollow tech crank it will fit. Crank length is on reverse of the crank arm near the pedal threads. 170,172.5 etc etc

    Is this compatible with Dura Ace 9170?

    Asked by: L931
    For Dura Ace 9170 we recommend the 4iiii Dura-Ace FC-R9100 Left Arm Powermeter as this will match the finish of your chain set.

    Does the 4iiii Precision 105 R7000 FIt the Trek emondo sl 5

    Does the 4 iiii Precsion 105R7000 fit a Trek emonda sl 5
    Asked by: Andyjohn
    If your Trek runs a 105 R7000 chainset then these will fit, making sure you select the correct length crank arm, which is written on the back of the arm located around the pedal thread. We hope this helps.
