Magene P515 PES Spider Powermeter

[Gigi27]

I ordered it last wednesday from the Ali Magene official store as I had a hefty discount (268€ with prepaid duty) but still no shipping confirmation... Today I asked on their chat and they told me that due to high order volumes, stock is insufficient and there might be delays, and my messages only reached their AI chatbot.
I truly hope that they actually have it in stock and will send it out before the automatic refund of Ali kicks in, it would really bug me to have to rethink my budget and re-buy it at a higher price...

A few rides and a quick aliexpress order later i have proper crankset spacers on hand.
Did not find any new/worsening scratches after removing the cranks so i'm calling the gap large enough for my meager power.
Definitely mixed something up as i had used a 1.2mm 3d printed shim before (not 0.7 as i thought), ended up settling on 1.3mm from a cheap muqzi set. It's just within the adjustment limits of the R7000 front derailleur.

It's definitely a bodge but it's my bodge.

Weight of the full 165mm crankset with R7000 chainrings is 805g, adding about 90g over the 105 crankset.
I've also attached a screenshot of the magene app in case anyone wonders what's in there.

i guess i need those shims as well for my p505base on my tt-x38 t47 bb.
currently the crank can spin just fine, but there are some scratches on the bb shell. 0.5-1mm outward on driveside may help

I already asked the question elsewhere and I was "friendly" advised to try in this already provided discussion.
Did anyone tried the combination of Magene P515 + Stone 48/33t 110m 4 bolts chainrings + T47 68mm BB and can kindly report how well it worked out?

Thanks in advance.

As you may read on the PES 515 product page both alloy and carbon cranks are compatible with T47. Chainring of your choice doesn't change anything. Can be Stone, Shimano or any other 110 BCD. This is new setup, so there's low possibility to someone already have it installed.

I really wish they would make a grx version… Or does anyone know how to make grx fd work with 105 crankset?

I read it on the Magene HP, but I´d like to have some confirmation from the field.
Probably it makes no difference whether it's a T47 68mm or 86mm and yet again I´d like to be sure.
Same question for what concerns the chainrigs: I'm using a 33t ZA Specialites on an Ultegra crank and it works fine, but someone reported that it doesn´t work that good with another 110 BCD crank.
It has been a while since I built my last road bike and there are a few factors which are quite new to me, so I´d rather like to know instead of guessing.
The frame is already ordered and it has a T47 68mm BB.

2.5mm of spacers to compensate for chainline and the height adjustment is up to your frame

On one bike I have a GRX 810 FD with an Ultegra crankset and no issues.
The GRX FD has a wider range and can be easily adjusted.
I have an Ultegra FD with a GRX 600 crankset on anorher bike and it works more than reasonably well.
The only issue is that the chain slightly touches the FD while on the smallest sprockets and I couldn't get rid of it yet.

I'm not the master in groupset, but I though the spindle lengths were different between them?

I'm not sure to understand what you mean.
I replaced an Ultegra crankset with a GRX 600, I didn't add any spacer and I don't see any play.
Beside, road cranks and "Gravel" ones are made for the same BB size.

I can confidently state that the P515 is not compatible with my specific BB386 frame (Felt VR '23, the old one, BB is token ninja TF38624), at least not without drive side spacer shenanigans.

Regular installation just ends in the cranks locking up fully once the bearing pretension is set by feel, the beveled face on the back of the spider collides with the very bottom edge of the frame.
After bodging a 3d printed spacer somewhere around 0.7mm, i didn't measure the actual thickness, i'm getting a gap i can stick 0.65 feeler gauges into and a 10km test ride went without anything feeling or sounding off.
I'll check for scratch marks when i get my hands on proper shims and adjust accordingly.

Obviously i'm not happy with the situation but i don't feel like admitting defeat either.

Bought it from 'EU Tax-free Discount Store' which went fine, arrived in seven days from france via fedex, balance and pedaling smoothness features were already unlocked.
Box showed signs of having been opened before, my assumption is that it is a chinese SKU and the seller activated the spider prior to shipping since the magene app did not have any activation prompt and just paired readily.

PS: excuse the account new-ness, i've been lurking for a couple years

was your box's bar code label written in chinese characters? my P505 power meter was confirmed by Magene to be a chinese market version by checking the bar code label this way

Still nothing from the Ali Magene store... I am now certain that they allowed far more orders than they could supply, the shipping date went from "a few days" to "may 28" to "june 02" to "ghosted" and the chatbot now doesnt even try to answer...
Meanwhile they updated the "additional payment" part of the order (for prepaid duty) in order not to lose it when the due date was near.
I wrote to Magene via email as well but they don't seem too receptive about it.
Maybe I'm being left on read because I used discounts and coupons and gave them less money than others, maybe I pressed them too much by asking for updates, but one thing for sure is that their support is nonexistent at best.
I will wait another few days to see what happens and then I will open a dispute to get my money back and look for other options.
It's a shame because I've only heard great things about their products.

I received mine today via Royal Mail, ordered on May 19th on their uk website. I’d been checking the provided tracking number but it never updated, then it just showed up.

I asked the Magene cutomer support and the answer was:

"Dear Customer,
Good day. Thanks for your support on Magene.

Regarding your inquiry, we need to clarify that our P515 is compatible with T47 BBs, including both the 68 and 86 versions.

Thanks for your cooperation in advance.
Best regards,
Alecia"

On AliEx (Magene shop) you can read:
Not Support T47-86.5mm and BB386 bottom bracket ！

So at least half of the CS answer is wrong.
I wonder about the other half.
