Re: Wheeltop EDS GeX It's pretty suspect that their 19 reviews all appear to be fake. A bunch of them even seem to feature pictures from the same bike :o

All reviews were added on between 25th and 29th of September. I received the marketing email with the announcement of the groupset on the 8th of October and there has been no reviews on their website since.

Re: Chainline help - Light Carbon LCG-071 and Sram Apex axs your chainline will be closer to the highest gear by a few mil, so your granny gear might get a bit noisy. if it bothers you too much you can always space the driveside crank arm out a bit and get a chainring w/more offset.

Re: Chainline help - Light Carbon LCG-071 and Sram Apex axs Their advice on chainline is pretty unintelligible to me. Having an LCG071 myself on which I run a 43.5mm chainline crankset, I really don't believe that a 54/42T could fit with a 43.5mm chainline. 46-30T just barely fits. Perhaps there's a typo, where:

Quote
If use double chainring, max 54/42T (chainline=43.5mm)，min 46-30T (chainline=47mm)

should actually read:

Quote
If use double chainring, max 54/42T (chainline=47mm), max 46-30T (chainline=43.5mm)

Similarly, I don't understand why they would recommend a max chainring of 42T for a 49.7mm chainline, which is a wider chainline than the 43.5mm chainline's outer ring (which sits at 46mm), or even that from a 47.5mm chainline. It would make more sense if they were recommending a 42T max chainring for a 43.5mm 1x chainline, which is what you get with a inboard-offset 1x chainring commonly used in 1x conversions.

In any case: I'm betting that with a 47.5mm chainline, you can run 54/42t max.

Re: Chainline help - Light Carbon LCG-071 and Sram Apex axs Maybe I'm misunderstanding, but Lightcarbon's specification doesn't mean you must have a crankset with ~49 mm chainline. It is merely the reference value for determining clearance. If you have a crankset with a smaller chainline value (i.e. more inboard), you probably will run into clearance issues with the specified max of 42T.

The ideal chainline for a 12x142 through axle back wheel is around 46 mm, but cranksets, especially gravel specific ones, sometimes compromise and are a bit more outboard to gain more clearance between chain/crank/front derailleur and tire. Or they might compromise to be more inboard to work better on "classic" 10x130 mm QR where the ideal chainline is 43.5 mm (e.g. 44.5 mm on Shimano road cranks).

Around 49 mm is the ideal chainline with boost (148 mm) axle standards, but those are almost exclusively used on MTBs.

Re: Chainline help - Light Carbon LCG-071 and Sram Apex axs Hi @RiegelundGel97, I'm sure what you mean about chainline, I guess is how far the chainring sits from the BB.

I have one of this frames and I built it with ultegra cranckset and the chainring fitted where the big chainring of 2x would fit and I used to run a 46T chainring, my rear derailleur is an Sram Rival xplr axs with a 10-45 Shimano cassette.

I don't feel it particularly noisy when I run the lowest gear but it's true that I found the transmission noisier that the standard ultegra that I run on my road bike.

I sent you a picture of the gap with the 40t chainring to show you the gap but as I said I used to run a 46T without any problem even if the gap was quite small

I had asked Peter NOT to send through UPS because on a few occasions they screwed me on overseas packaging. To my horror (for a few days) he told me that regular post was not possible and HAD to send UPS. I just checked tracking and fees this time were only $30 CDN. I am not sure why it's so low but I will take it. I have paid UPS that much brokerage for 2 tires from Europe LOL.

 ETA on my frame is Jan 11.

Hi Dave, SO sorry about this, after you told me not to send through UPS, I thought we should be able to send by EMS, but when we were about to send the package out, the EMS staff here they told me not possible to send through EMS because of the strike. And I checked with another client from Canada he said it is OK with UPS shipping and FedEx. Even I charged you on EMS shipping fee which is cheaper than UPS shipping, but not to delay delivery, I sent your package out through UPS as well, since the EMS staff they don't know when EMS gets normal again. Anyway, SO sorry if this causes any inconvenience for you. BTW, UPS charges way more than the fee $30 CDN you mentioned from us.

Re: Survey: Chinese electronic Groupsets Groupset: Ltwoo ER9
would you recommend? Only on sale (bought for 350$) and if you already have crank and cassette
where bought? Aliexpress Ltwoo official store
mileage: around 1200km so far
flaws?: Shifter buttons are mushy. Sometimes hard to tell if pressed or not, especially with gloves. Impossible to remap the buttons. Stupid brake calipers(replaced with zrace). Front derailleur cage shows a lot of cosmetic wear

Re: Survey: Chinese electronic Groupsets Groupset: Ltwoo ER9
would you recommend? Only on sale
where bought? Aliexpress 80 Designer Store
mileage: around 2500km so far
flaws?: Front derailleur cage shows a lot of cosmetic wear.  Two or three times no shifting at all or when i "SRAM"-shifted. Only option to solve this, was to connect to a battery via cable (phone during ride). And the breaks are only okay on the flats, but awful on descents. Replaced them yesterday with ZRACE XG4

Re: Survey: Chinese electronic Groupsets Groupset: Ltwoo eR9 2x ver. 1 (I own two)
Would you recommend? Only on sale and if you know what you are doing ($350 USD)
where bought? Bought 2 groupsets, 80 Design Store (highly recommended) / LTwoo Factory Choice Store (only buy here if you know what you're doing)
mileage (roundabout): Several thousand miles/kilometers
flaws?: Highly recommended to protect battery connectors with dielectric grease, liquid tape, rubber cement, etc. Swapped out pulley wheels for Ultegra wheels, FD shows lots of brassing, FD shift buttons can easily be pressed on accident. Some batteries do not give accurate charge readouts. Also there are several silent hardware updates, components are running different firmware. Despite the flaws and if you're able to figure it out, it does the job.  LTwoo app is solid with real-time adjustability and feedback. 10/11/12 speed cassette flexibility and replaceable batteries are a big selling point for me. Version 3 seems to address many of the issues of ver. 1, unfortunately it will be now difficult to obtain for US customers.

Groupset:LTwoo eGR 1x original cage length max 46t cassette (silent update on cage now allows max 50t cassette)
would you recommend? Yes especially on sale ($300 USD)
where bought? LTwoo Factory Choice Store (Only buy if you know what you're doing)
mileage (roundabout): Several thousand miles/kilometers
flaws?: Highly recommended to protect battery connectors with dielectric grease, liquid tape, rubber cement, etc. The eGR shifters have better haptics than eR9 ver. 1. RD is very sturdy, with minimal chain slap with quick shifting. Same LTwoo app for tuning, though they need to implement tuning profiles for different 1x cassettes. Gravel bikes have to deal with XD, HG and MS freehubs, so more issues with fine tuning across different freehub platforms.

Re: Sensah Electronic Groupset (14 speed?) Ah right, I suspect you guys are in the US and need to factor in the Trump tax.
