Hi everyone!

I’m having an issue with my Wheeltop EDS GeX Gravel 1x12 and wanted to ask if anyone has experienced something similar or knows of a possible solution.

Unfortunately, Wheeltop hasn’t been very helpful so far. I reported the problem with videos and a detailed description, but apart from telling me that the one-year warranty had expired, there was no technical analysis, troubleshooting, or offer of a replacement shifter. In the end, I was basically told to buy a new groupset.

The problem is with the right shifter:

Both buttons are no longer detected separately.
I can change the button assignment in the app, but both buttons always perform the function assigned to the small button.
Example: large = “+”, small = “−” → both shift “+”.
If I swap the assignment: large = “−”, small = “+” → both shift “−”.
The shifter itself is detected normally in the app.
The current gear position is also displayed correctly.
Shifting via the app works normally in both directions.

I have already tried:

Replacing both shifter batteries (3.3 V)
Updating the firmware
Re-pairing the shifters
Resetting the system
Resetting and testing the button assignments several times

Does anyone have any idea what could be causing this? Maybe someone has experienced a similar problem or knows whether the shifter can be reset/relearned separately, or whether this sounds more like a hardware failure?

Thanks!

I'm having an issue installing OX 2 rear derailleur.  Specifically the chain doesn't appear to run over the rear pully correctly and rubs against the top of the cage when pedaling.  I assume I am doing something wrong - can anyone offer some advice?  For reference the chain is a Chinese made 12 speed that was working fine previously with a GX Transmission rear derailleur.

Narrow-wide pulley? Make sure to fit the pulley correctly to the inner and outer links of your chain.
Had the same issues while installing my GeX derailleur before realizing that I was stupid

Have a look at the Carbonda 1136.
It fits 35mm tires measured and has a designated Endurace Geometry.

Just ask if it's possible?

Hey!

I want to pull the trigger on this 1136 but i'm a tad skeptical on the aero properties of the frame and the matte black pictures on carbondas website hide so much detail.

Does the fram actually have an aero build like alot of the modern road race bikes out now? Hard to tell but does the head tube have an hour glass shape and are the fork blades aero? Is the seat post completly round ior does it have an elongated oval shape for aero?

I really want my next bike to actually be an aero upgrade so just trying to enusre this has some of the properties of newer aero frames before commintting. Thanks for the help!!

I wouldnt say its super aero, but it certainly has some aero aspects. Made some pics of a frame I have access to.
Head tube has hourglass, shape, the fork blades are also aero. seat post is round. Hope this helps.

Another question, what size would you guys recommend for a rider with 186cm size and 91cm inseam? Focus on relaxed riding, ultracycling races.
I'm torn between L and XL...

(what a shitty software this forum has )

That should be the Vitus ZX 1  Evo.

Geotabels are slightly off, but to my knowledge its the same.

Yeah and all his arguments are 100% empty, baseless statements and promises.
It's like a crack user doing tricks on skid row telling you he could be Elon Musk or some retarded $hit like this.
You willingly bought from a guy like this? Why? He literally answered none of my questions convincingly. Not one.

I can relate.
Answers are unprecise, not to the point and the crappy google translate wont help either.
Even I asked him like a lot of times and explaining, he was not able to make clear if or if not his shipping includes taxes and how much shipping is to Europe. Hm.

 Did you take some pics of the inside of the frame?
There are some quite bad pictures of the internals of the frame on the Aliexpress seller you mentioned.

Bought in the end the same frame in size 56 with T1100 carbon, according to the seller on AliExpress (for what it's worth).

Weights are:
Front fork (uncut): 452 gr
Seatpost (uncut)+clamp+rubber: 229 gr
Handlebar with integrated stem: 331 gr
Frame incl: bolts+seatclamp: 1069 gr
Parts: headset, spacers, compression plug: 153 gr

Total weight of: 2234gr
costs incl. shipping to Europe with DPD was 682 euro's

Need to build everything together, just waiting for some parts though.

Bought a Deda D-fork compression D-plug after this comment:
For the rest will I hijack this topic thread to continue the build of the same replica Factor Ostro VAM. The picture is just for indication of how it looks like, so I know there are no headspacers, etc.

The bottom bracket was not included, but alu axles were. those were 64 gr but I placed those at the wheels section so they are not in the frame weight calculated.

For the rest I have the Lexon Carbon crank and the wheeltop derailleur set. I will go for a 1x setup with a 52 chainring as where I am based it's quite flat.
Probably will go for the Elite Drive wheels or Superteam, I haven't decided yet
