Hello Shane,
I just saw the Magene P505 crank based power meter and wanted some advice
I have a GRX600 crankset with 46/30 and was looking to upgrade to 48/31. Instead of upgrading to GRX810, I thought of upgrading to the Magene Powermeter with 48/31 chainrings. Is this possible? If yes, what would you recommend.
Any recommendations or advice?
Buyer beware, Magene is not a legit company. They have zero support behind their products. If you have any issues, you’re on your own as they do not respond when contacted. While the P505 maybe be accurate, it will fall apart after a few months use… Avoid!
Two questions – What was the issue you’ve had and where did you purchase it from?
Hi,
In my experience their customer service was very prompt in responding to my inquiry and very helpful. (In the end they suggested purchasing a spare bolt directly from the factory, which I appreciate. However, I was a bit uncomfortable providing my ID card number along with my shipping address).
Now, I have a question here regarding the M5 bolts on the left crank: Are these standard, universally available bolts, or are they custom made?
With regards, Davor
G’day Shane.
New to cycling and power meters, so please excuse my ignorance.
On Magene website it states that this power meter is not compatible with BB386 which is what my bike came with. It is also equipped with Shimano 105, 11sp mechanical group-set.
In your review, you say that if I am riding Shimano road groupset, it is a very easy swap in process.
What am I missing? I would like to buy it but would hate to find out that it does not fit my bike, so I would appreciate if you could enlighten me here..
Many thanks in advance.

That’s one for a bike mechanic who’ll be able to advise on a BB386 -> Shimano 24mm spindle crankset conversion / options. Not something I’m across sorry.
Hi Shane,
Thanks for the prompt reply and for the great content you publish.
Keep up the good work.
Best

Hi Shane, do you know of any other crankset compatible with the power spider? i’m looking for a 160mm crank length, but i cant find which standard they use on the spider provided with the PES crankset, doenst look like sram 8 bolt or 3 bolt. TIA
Best contact Magene on this one. If I recall correctly, they’re using a direct mount standard of some sort that wasn’t what I expected.
Hi Shane, is there coming a review of the new PES 515? I’m considering it because it’s cheaper than changing my 4iiii setup from 172.5 to 165mm cranks but i cant really seem to find any reviews or firsthand impressions on the 515 only on the 505. TIA
Yes, it’s on the cards to review. I have the P515 to install and test.
