I’ve been looking to get a powermeter on my Diverge since I got it, but i got the 2x10 setup with GRX600 cranks. I managed to find a stages GRX 810 PM in stock and want to make sure this would be compatible before I pull the trigger. Does anyone have experience mixing and matching 600 and 810 cranks? Would it be better to get a full 810 crankset?
Shouldn’t be an issue be sure they’re both the same Hollowtech interface.

I have the Easton/Race Face/Cinch bottom bracket powermeter on my gravel/CX bike. So far so good, although I just got a set of assioma duos and according to my initial and poorly controlled testing the cinch can read up to 10% lower than the assiomas.
they read almost dead on with my powertap hub and within 3% of my kickr so I don’t think it’s that.
I have one as well - 46x30 setup. Nice low gearing with a 36T cassette.
See this thread, which should quell any fears at all about using Assiomas for gravel riding.

I use them on my road bikes and my gravel bike. It’s fine. I do probably wear out cleats a little faster than normal, but I don’t love hike a bike, so I try to keep that stuff to a minimum.

I put a Shimano 105 left crank only 4iiii’s on my Ridley last week. Have a gravel race this weekend, looking forward to data collection. Cheapest option I found ($275 from Speed Vision)

I just bought my first gravel bike (Trek Checkpoint SL5) and naively tried to put a left crank arm power meter on it like I had on my road bike. Turns out it did not have enough clearance for that. What I ended up doing was sending my crank into 4iiii to have a right side only power meter installed onto my crank. I am used to riding with power and I sold my road bike and just have a gravel bike now. I bought a second wheel set and set it up with road tires. With this being my only bike I really wanted a power meter on it. It was $300 and around two weeks for the install.

The SL5 comes with the GRX 600 crankset which is not able to have a 4iiii installed on it. What crank did you send them?
The only one the Trek Store had was actually a carryover from their 2020 stock so it still came with a 105 groupset. That was one upside with 105 vs GRX, is there was a lot more options for power meters. It took me a while to actually find someone who had a bike in stock for me to get so I did a bunch of looking around and did some looking into what I would do for a power meter if I got a bike that come with a GRX groupset. I believe a 105 crank would be compatible with the GRX Crankset.
I have a 2020 Checkpoint SL5, which came with the GRX600 groupset. I swapped to an Ultegra Crankset (wanted a compact instead of the sub-compact and had the crankset in my parts bin anyway) and a Stages XT left arm. Even if you wanted to stay with the GRX, it is Hollowtech, so can swap to a Hollowtech compatible MTB left crank power meter and have the needed clearance.
That can work, as long as you run 170mm or 175mm cranks, since they don’t offer 172.5mm for MTB.

Good morning all. I bought myself a gravel bike about a year and a half ago. Really love the bike. Got kind of a cheap one so I’m starting to upgrade components. I’m changing out the BB and cranks from a cheap square taper and cheap 1x crank to hollow tech and some old ultegra road cranks with a narrow/wide single chainring.
I’m thinking of putting a stages crank on it but, I’m wondering if I shouldn’t leave a power meter off the bike and just enjoy the ride. When I ride the gravel bike its nearly always easy to get my Z2 training.
What are folks thoughts on this? I’m using heart rate TSS to quantify the rides but HR is kind of a fickle metric.
It depends. If you’re mainly going to do Z2 (of 5 or 7) rides on it, the power meter is pointless. In fact, for Z2 riding it’s better to go by breathing rate or heart rate, since that’s the best indicator of your physiological effort, which is what your after if you’re trying to train Polarized or Inigo San Millan methods.
I put a Stages GRX left crank on my Topstone. Been quite happy with it.

I’ve got the Garmin Rally XC100 pedals and they’ve been great. Pedal strikes and water crossings seem like no problem. I replaced the battery after about six months but other than that no problems.
I’ve been using SPDs for years so they worked great for me.
I’m using a SRAM/Quarq pwoermeter on my Checkpoint, both for road and gravel.
The PM works fine. The only “caveat” is intervals on gravel is a lot harder - at least around here, the gravel roads have lots of short punchy ups and downs, so consistent power output is impossible.
I started out using the SRM X-Power shortly after they hit the market and I am now on the third pair, which finally seems to work consistent.
While dealing with issues in the pedals installed Power2Max NGeco on my 1X SRAM Force drivetrain and I am very happy with it - it is reliable, consistent and matches the KickR very well.
MTB and Gravel/CX bike are equipped with Power2Max and I use the X-Power pedals on other bikes or sometimes simultaneously.

My gravel bike, which is more accurately is a CX bike, has a left side 4iiii 105-7000 PM on a GRX400 crank. Works perfectly fine.
