I have put Wuzei 4 Bolt 110 BCD Chainrings on my Magene P505 while i am waiting for my frame so i can build it all together:
Does it run without any problems or should i get other chainrings while waiting for the frame? I am asking because the Wuzei ones dont have any chaincather(?) on them so i am not 100% sure if ther might be problems. Also because i am a bit sad i didnt get the 505 with it's original chainrings - because on a second guess those look kinda cool.

I had a  Wuzei chainring : https://www.aliexpress.com/item/1005008844119020.html?spm=a2g0o.order_list.order_list_main.5.e64018024ZfFBL , but it did not run cleanly, there was a weird feeling, and noise, I was worried so I bought another Pass Quest one, and the problem was gone, so I don't recommend it. I was using it with a 12spd chain 1by, Wheeltop GEX with 13spd cassette.

You could try a 52x40x7 bearing with 45/45 degree and another crown race

Thanks, that solved it, weird that this FSA bearing is not that standard, I won't change the top one, because for that I would have to reroute the brake hose, but with the bottom one it seems fine.

My frame has arrived, and I've built it, I have an FSA No 69 headset: https://www.fsaproshop.com/products/no-69-srs
I have a rockshox rudy fork, and it seems like there is no gap on the crown of the fork, on the top it seems fine. I can't tighten the headset enough to not have play, but If I tighten it a bit more the fork won't move freely. What shims do I need, and where should I put them, or what should I do?

Thanks!

Do you know how to record shifting data into the garmin fit file?
I've added the shifter as gear sensor, I can see the shift ratios in the data screens, but shift data is not recorded to the fit file.

Never mind, it did show up in the AXS viewer after I connected it to garmin, I think that the trick was to show the Front and Rear gears on the corresponding datascreen.

I have bought the second one with 165mm cranks, it will arrive this week, hopefully it will have the updated bolt design.

It arrived, this is the new bolt design, right??
One caveat, that this is the chinese version, and the pedal balance and smoothness requires payment, but I contacted the seller on aliexpress and sent the serial number and he activated within an hour, so I didn't have to pay for it.

This bike is pretty fast. Took it on a 75 mile gravel ride today. It did really well in the sand pit areas with the 50mm tires on it. 5 stars for this bike

Do you really need a chain guard with wheeltop gex? I'm also thinking about this specific model of chain guard.

No, they're similar to Shimano using something similar to the shadow derailleur hanger design. I tried setting up a Shimano direct mount hanger on my UDH bike and the LTwoo RD wouldn't fit on a Shimano specific DM hanger. It's slightly different.

So just have attach it to the hanger directly? Does that work fine?

If waiting is an option, the new Ltwoo eGR version is supposed to have a larger max cassette capacity. Also, their new MTB derailleur looks interesting, especially since it seems it likely pairs with their road and gravel brifters.

Thanks, I think I will wait for now, 80 Desinger store answered me and said that the new eGR will be available in the end of the month.
I have one more question, Wheeltop has a specific interface with UDH hangers, does LTWOO have something similar?
