It seems that more Chinese manufacturers are interested in penetrating the groupset market, which is dominated by Shimano and SRAM. After Ltwoo, Sehsah, and Wheeltop, Magene is a new player. They showcased their QED 12spd road groupset at Shanghai's China International Bicycle Fair. I got this info (and pictures) from a person attending the fair. So, there might be some discrepancies. Anyway, here is what I know:
- 12spd semi-wireless groupset
- looks like Shimano 105
- it will have hidden buttons on the inside
- hoods/shifters compatible with rim + hydraulic disc brakes
The price or the release date is unknown. What is your guess?

Now this is gas

How can the same shifters work with both brake cables and hydraulic housing?
-
Certainly interesting if they can get a product to market and throw some good support behind it (support historically for Magene products seems... lacklustre). For example, see this thread:
https://chinertown.com/index.php?topic=4221.0
The P505 certainly seems to have been a success for them though and they've at least shown with that that they can make a reliable product.

This is hype. I feel like magene quality is above the rest

They also have powermeter pedals promising to compete with assiomas. Wish they made PM cranks again though
But what happened to sensah?? I think they were the second teased electronic groupset from china after wheeltop but i've not heard about it in over a year

Joe said rim brake will be available later so they are not the same shifters

My source sent me this photo that Magene told him about the shifter disc + rim compatibility. But I honestly have no idea how it works.
-
Well that is a great idea.
You just need to provide a way to connect a cable to the lever along the hydraulic cylinder.
So if you use hydraulic, you just use cylinder. O
f you use rim brake you actuate both the cable and cylinder at the same time, but cylinder does nothing.
I wonder how nobody thought of that before...

I would guess it makes the shifter bigger...

According to the Chinese conversation in the cyclisthub video, the hole on top is for mechanical brake cable. The hydraulic brake hose goes to the traditional location below.
It's one single design that accepts both mechanical and hydraulic braking. Neat.

PM Cranks are mechanically speaking an inferior design to spider PMs. For spider PMs they are build with a pair of sheer gauges that can naturally filter out components of applied torque that are not due to rider pedaling, while crank based PMs rely heavily on post-processing to clean the data to a usable level. You also only need one side to measure true L/R combined power (though the power decomposition to L/R is still more or less guess work), which is especially good if you have a pretty big L/R difference (For me it's 56/44, so a left-side-only setup would overestimate my power by quite a lot)
-
I used to have a similar power imbalance. You may need shims or insoles. However, just lowering the saddle 1.5cm for me made the balance equal.

I just really want directmount chainrings

Why

Why
Subcompact options that are hard to get with BCD, plus the rings are very pretty

I bought Magene's QED crankset with direct-mount chainrings before it got pulled from the markets. Horrible experience, Magene bungled the design and they would bend and become permanently deformed from normal pedaling loads. Magene's warranty department was useless and asked me to delete my chinertown thread on the issue to cover up their screw-up. The most I got from this was a new chainring, which bent again. My experience might be part of the reason why that product got pulled from the shelves in the first place.
Even worse, they have a proprietary chainring interface and no aftermarket spider or alternative chainrings, which means I am completely fucked and have a $500 brick of a crankset. In summary, be thankful they learned from their mistakes and aren't making DM chainrings anymore.
I know the spider based PMs are great, PES is great, and their accessories are great, but damn do I feel bitter about Magene after my QED experience.

I have worked with both a professional coach and a fitter. Position is much more comfortable for me now but I still can't get my imbalance to improve.

oh wow. Asking you to delete threads on here is really something. i guess public forums really are important consumer protection / decision tools.

My QED powermeter crank and chainrings are still ok after 2years.

What's the difference between the QED chainrings, and the optional chainrings supplied with the PES? I'm trying to understand by Magene's QED video.
Are the QED rings similar to SRAM Red's one-piece design?

As a follow-up:
The QED crankset was launched in 3 versions. 1) A standalone crankset with the integrated chainrings, no PM, 2) crankset with the beloved spider-based PM and bolt on chainrings--the exact same PM and rings as on the PES, and 3) with integrated chainrings and Stages/4iii-style P325-model PM in the crankarms, dubbed the "QED P325".
You can watch my unboxing on the P325 model video here: https://www.youtube.com/watch?v=mt1B119gEiA&t=157s&pp=ygUKbWFnZW5lIHFlZA%3D%3D (https://www.youtube.com/watch?v=mt1B119gEiA&t=157s&pp=ygUKbWFnZW5lIHFlZA%3D%3D)

Basically QED just denotes that it's DUB spindle. Can be any configuration.
PES is for 24mm spindle.
