Re: Magene P505 PES Base Spider Powermeter I have the P505 Base with the cranks from Magene. Price was $300 USD with free shipping. Installation was very simple. Straight swap from my Shimano 105 cranks, preload the non driveside and then a single pinch bolt. I'll post the weights below. So far, data has been tracking spot on with my Favero Assioma pedals except in one condition. It does not work well with oval chainrings...sort of. So my setup is a little weird. I do a round outer ring and an oval inner ring. This is why the Magene has problems. It's a well documented "issue" that spider power meters overestimate oval chainrings. Which isn't a problem in itself because you can adjust the offset of the PM. So if you're running a single ring oval, just can adjust it down to be accurate. Or if you're running 2x oval. The problem I'm having is that it's accurate for the round outer ring, but reads high when in the small oval ring. My solution is that I ordered a round inner ring. It's on the race bike and I wanted to get bigger chainrings anyways, so I'm fine with using round rings. The other option would have been to just know in my head that the readings were 10W off in the small ring, but my solution seemed simpler.

Overall, very happy with it. I wanted a cheap, accurate PM for my crit bike and this is it. Easy swap if you're running Shimano, and very accurate readings with round rings. I would buy again for sure. Magene is also making a pedal PM that looks promising but it's going to be a bit more expensive.

Weights
PM Spider: 112g
Driveside crank arm and spindle: 312g
Non driveside arm and preload bolt: 213g
Total weight (no chainrings): 638g

Re: Workswell disaster That's interesting. They clearly are OEM for various brands (niche, probably), because sometimes they will quote you for a frame for 1 country, but not another, unless you ship to another country and so on, or will have a MOQ of 5 or 10 frames. Clearly there are exclusivity clauses at play.
They're also quite expensive even if ordering 5 or more frames. All i could get out of them was "we use Japanese carbon fiber and it's more expensive". Ofc they claim they are really good at quality, but find me a shop that says they arent. Point being, i never worked with them because the frame would always end up costing 50+% more, and emailing with them is always like pulling teeth, i never got the impression that they wanted my business.
Maybe they just low key suck and charge more for no reason.

Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc!
I failed the test.
Ltwoo ER9 incoming
Ltwoo EGR incoming

Yep, glad it's over. Now how do I explain this to my wife?  ;D
Just like they do when buying clothes: you just say how much you "saved" by buying in sales.

Re: Interesting Aliexpress finds! - good deals, interesting stuff, new products etc! Found a guy on chinese forums who made his own powermeter at home

Also learned today they REALLY don't like the brand rockbros there and have some pretty creative insults and threats towards them

Re: WheelTop EDS TX Full Wireless Groupset (Chinese SRAM) I dont buy my bikes on aliexpress and i've had several warranty issues / goodwill instances when my counterparts did the right thing. I've had 2 or 3 warranty / crash claims with Farsports, i've had velobuild send me their updated C rings free of charge, i've received wheels that were centerlock after ordering 6 bolt and received adaptors free of charge. I've had a derailleur replaced free of charge & received a bunch of freebies.

Long story short, there's more to dealing with chinese counterparts than aliexpress & assuming no warranty coverage. I'm the highest tier on aliexpress and usually (not always) they are helpful. I had a bad experience with Alibaba, they clearly gave no F about me, that was disappointing, but i'm not going to cry about it, after all they were sticking to their T&Cs.
In fact 2 weeks ago i ordered via aliexpress a replacement crank arm for cheap. I shouldn't have paid for it, but this seller is a dick and i'll do my best not to work with them again. Either way it should save my ass for cheap enough.

I guess my point is: build relationships with sellers you learn to trust. It's so much easier than it used to be to have clear discussions with them. Either they speak decent english now, or they use translation software that actually works. It used to be an uphill battle to make yourself understood. Now i feel i can ask very detailed questions and i usually get spot on answers.

Last: the vast majority of people still assume that if it's unbranded and chinese, it's poor quality. I have friends who to this day will not use an unbranded chinese bike out of fear of death. Sadly (?), some of them are actually highly educated people with engineering degrees placing them in the 0.01% of the population. Others are just Luddites. Which ties back to Factfulness, in fact.
Most of this forum exists to navigate issues around oval holes, unfaced brake mount surfaces, out of tolerance interfaces, and structural integrity of parts. Together, usually referred to as QC. Aka, quality... Aka, who to order from to minimize the chances of ordering a dud.

Be curious to know why and read some examples. I didn't think its any worse than numerous other Chiner brands but you never know.

Re: Airwolf YFR068 - 2023 Gravel Frame Last Saturday I put the bike to test during one of Europe's biggest gravel events, The Traka in Girona, Spain. First time for me and joined the 200km route with 2500m elevation. Bike got some serious beating and did not let me down, it's still in one piece!  ;D

Re: Airwolf YFR068 - 2023 Gravel Frame
Replace the compression cap with this part?

No, I think what they've mentioned in the previous post is a compression ring that holds the headset bearing. The compression plug you are showing does not fit in the steerer tube since it's D-shaped.

Specialized sl7 compression ring

Re: Airwolf YFR068 - 2023 Gravel Frame
Yes, exactly the same. Both bearings are the same for this frame also.

Thanks! That's very interesting, and obviously different to OEM Aspero which uses two different sized bearings.

This forum, and this thread, has been so useful, I'd be hitting my head against the wall if I tried to go alone with it.
