See attached photo. This cassette has been super cool and lightweight, albeit has exhibited some very rough shifting around the 3-tooth jump between cogs 7 and 8.
After no more than 100 miles of riding I noticed a tooth was sheared off. Thankfully I was granted a return (after nearly 3 months of ownership), but I'm posting this as a fair warning to everyone else.
I've found some centerlock hubs by Goldix on AliEx designed for 21-spokes and 2:1 lacing patterns, that is 14 crossed spokes on rear drive-side and 7 radial spokes on the rear non-drive-side, and 14 crossed spokes on the front non-drive (disc) side and 7 radial on the drive-side:
These are the same lacing principle as Campagnolo G3 or Fulcrum's wheels, which is designed to even spoke tensions across drive and non-drive sides. It appeals to me, because in my mind I think it means I can get away with fewer spokes and have just as strong of a wheel. Also, when I spec these hubs with Pilar wing 20s and high-spec Deerobust rims, I get STUPID light weight predictions, like under 1350g for 55mm rim, or under 1300g for a 50mm rim.
The questions I want to field here:
Do people think these should be laced as a 3x or 2x pattern on the crossed sides? When I model it up in solidworks (embarrassingly, I found this easier than calculating the spoke lengths), the spokes come out of the hubs straigtest when laced 3x.
Do we think there is anything dangerous about going to 21 steel spokes, on say, a 50 or 55mm rim? I see that campag runs 24 spokes on their WTO rims, and I'm wondering if that's because 21 spokes is simply not going to be stiff. I want to hear your thoughts.
I'm selling what's left of my used LTWOO R9 11-speed carbon-edition groupset for spare parts after breaking my right-side shifter body. Pricing is dictated by aiming to undercut Panda Podium's pricing for spares + pay for shipping & 30min labor of packaging and taking to post office, but I'm happy to field offers.
Shipping only within the USA. Prices are in USD. Pricing includes shipping via US priority mail, which is about $11 per item. If you're interested in buying multiple items, we can negotiate for a lower price.
I ordered a frame from LightCarbon at the start of the month, and was given an estimate 15 days production time before it shipped. Now it's been 24 days. I emailed them 15 days in to check in on the status and they said it would ship this week. This week has almost come and gone, and...nothing.
I had planned on using this frame for cyclocross season and at this rate I'm not going to get a frame in time. Should I pull the trigger and dispute with PP (I did purchase with buyer protection), or is this kind of kicking-the-shipping-time-can down the road par for the course?
I ordered a Magene QED P325 power meter a few months ago and wanted to share some disappointing news. I've always noticed the chainring had a bit of runout, but didn't think much of it. It wasn't until I put an Ultegra derailleur on that the problem became really noticeable, and it's pretty much impossible to set the front derailleur now. I've tried making a warranty claim, complete with a video of the runout, but the Magene email support punts me to the dealer support, and the Magene official store on aliexpress claims this amount of runout is normal, and refuses to send a replacement.
I've uploaded a video to youtube () titled: Magene QED P325 chainring runout, which clearly demonstrates the problem, and I use the video to estimate that the magnitude of the chainring runout is 0.9mm. Clearly unacceptable.
Even more frightening, the Magene website page on warranty says: If products purchased from other official Magene channels (for example, AliExpress, Amazon, etc.), the warranty policy of that channel shall prevail.
From this, I get the sense that Magene is basically putting me at the mercy of their Aliexpress dealer for all warranty claims.
I think it's really disheartening to see Magene let customers down like this at the warranty step. Magene postures as a premium brand, with premium prices for the China-components market. I paid $500 for this crankset. You would expect at least a modicum of warranty service. All this warranty claim would take is sending a replacement chainring, which I've seen on AliEx for $75. Why they refuse is beyond me.
If you are thinking about buying from Magene, I seriously would reconsider and think about the warranty service you've seen people receive.
There are many alternatives to Magene power meters and cranks. There is Sigeyi. There is XCADEY. An XCADEY power meter and crank is a similar claimed weight as the QED and costs about $100 less.
