Re: Magene QED 12spd groupset showcased in Shanghai
I just really want directmount chainrings 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. May 07, 2024, 10:02:33 AM |

Re: Which OM frames are these?
I LOVE how they're trolling Factor logo & paint schemes. The RS1 looks like various workswell / yishun / lightcarbon models, it's for sure OEM. The SL1 could be a VB 177, bearing in mind VB is a broker, not a factory. It looks similar, but slightly different, for eg, to a long teng 266. I dont follow gravel much. Those boutique brands are basically a scam, it's incredible. May 15, 2024, 08:51:01 AM |

Re: Deerobust/Goldix wheel build 50/55mm 1319g
If this really is your first ever wheelbuild then you chose something with quite the steep learning curve  I've been building wheels for many years. I started out with rim brake alloy wheel stuff mostly for commuters and urban bikes, like lacing wheels with hub dynamos and stuff for myself and friends. From there I went to building more complex spoke patterns and carbon wheels and so on. I agree with most of your choices except for two: A 2:1 spoke ratio made a lot of sense on rim brake rear wheels IMO, where one side took all the torsional load and therefore is laced in a 3 cross pattern while the other side can be laced radially (which is how the Ford factory did it way back on laced car wheels when they invented the idea). It made sense because of the drastic difference in spoke angles with the DS spokes being much further inboard due to the cassette. Ever since disc brakes, both side's spokes had to move inboard and the difference in spoke angle and tension isn't as bad as it used to be. So the advantage of 2:1 isn't really as big as it used to be. Personally, I stopped doing it. I do think that asymmetric rear rims with a slight offset to the NDS make sense to further correct the difference in spoke angles. But that's about it. The other thing is internal nipples. I think it's not worth the hassle. Sure, you chose superlight rims so it might be better to err on the side of caution. But I think Enve's argument that this makes a sturdier rim is marketing bogus. What is much more important is that the rim bed is reinforced as a whole, which is the case with most carbon rims. And it's important that the spoke holes are drilled cleanly and accurately in exactly the correct angles, so as to not cause stress at the nipples and threads due to bending moments. This is the case with most well made rims, but I had bad examples from some Chinese sellers. Like you, I've sourced rims from various Aliexpress sellers over the years. The aero benefit of internal nipples might be there. Honestly, I don't care. If you ever choose to run your wheels tubeless it'll be a huge PITA to access the nipples should you ever have to. Also, since weight seems important to you, it'll increase spoke length and therfore makes the wheel marginally heavier. A well built wheel will usually not go out of true. But there can be incidents like hitting pot holes in a race or whatever. But like many things in wheelbuilding, this is just my philosophy. I think you did a stellar job and built a super impressive wheelset. Congrats! And it's a really nice feeling to be riding around on one of a kind wheels that you yourself built.

Re: WheelTop EDS TX Full Wireless Groupset (Chinese SRAM)
And you should be able to disable this crosschain protection in the app. I set it up for 11sp…and sometimes it might be necessary so increase the values which are standard setup. eg…for my edco 11sp I had to up the value of the 11th gear from (~) 1760 to 1840, so the derailleur was able to reach the full range…. Since that initial fine tune I had not a single misshift or whatsoever on my gravel bike….setup with 46/30 oval 11-34sp And btw….support very responsive! May 16, 2024, 01:14:29 AM |

Re: WheelTop EDS TX Full Wireless Groupset (Chinese SRAM)
There's also a TX-R7101-SGS derailleur mentioned there - TX is for road, but SGS is long cage. It might be that this is a wide-range 2x option. If it's a 2x gravel electronic groupset, I'm sold. I hate 1x. I prefer riding to the trails which requires doing road miles beforehand. I find driving to a trail just to ride a bike to be incredibly lame. Probably accounts for why most of MTB'ers I see in my area are switching to e-bikes to make up for their lack of fitness! May 16, 2024, 07:04:46 PM |

Re: WheelTop EDS TX Full Wireless Groupset (Chinese SRAM)
The cranks are their own and they do make an mtb cassete. They also sell some stuff to decathlon

Re: LTWOO eGR
I had a problem getting the ER9 LTwoo calipers+140mm adapter plate to line-up properly using 140mm rotors on the rear. I tried it on 2 different framesets and both of them would not line-up properly. The strange part is that I had no issues running 160mm rotors with the Ltwoo calipers+adapter plate. I ended up switching over to ZRace XG calipers which required no adapter plate. I literally just unscrewed the Ltwoo calipers and screwed in the Zrace calipers, plug-n-play style. They work well enough with no issues on long descents.I have to say that I strongly discourage the use of this disc rotor. It completely neglects mechanical simulation and the bracket itself is prone to fracture. Furthermore, the pattern design is a mess, with hollow patterns distributed unevenly on several concentric circles. As a result, the friction rate of the entire disc rotor in the radial direction cannot achieve consistency, leading to the formation of grooves on your brake pads... It's a design that leaves me speechless. The issues mentioned above are not exaggerated claims but rather highly probable events that have occurred multiple times on Chinese forums. I don't want anyone else to become a victim of this disc rotor. May 17, 2024, 10:59:41 PM |

Re: WheelTop EDS TX Full Wireless Groupset (Chinese SRAM)
Save us magene This is quite literally Magene's warranty policy: https://support.magene.com/hc/en-us/articles/900002358986-Warranty I got served this bullshit when the integrated chainring on my $500 QED crankset/powermeter went out of true. They sent me a new chainring "out of generosity", but never refunded me. I'm pissed. They damn well know the product is defective because they pulled it from the shelves, but never made me whole.

Long term experience with RD13 hubs?
Hello everyone, I´d like to know how long these hubs can be expected to last, even in wet conditions, what is the delivery status (do they need some more grease anywhere?) and how high would be the effort to replace the bearings. The alternative I have would be the DT Swiss 350 hubs. Thanks a lot in advance May 26, 2024, 02:05:45 AM |
