This is different. they are saying that the only way to buy their products is via their website.
what you are saying is what LTWOO is doing for eg, which is, in case of warranty issues, you contact your reseller, and the reseller liaises with LTWOO. I know that 1st hand, given i'm now on my 3rd dead ER9 RD, and every time i go through the reseller, which is torture.

Well, if oyu think going directly is a blast..no way....

The sellers just do not care....

Hi - looking at the 1306 from carbonda, I was wondering if there is a better option?

I've built quite a few. They are easy to build, nothing special. And ride well.
Since you are looking for better. What would you change on this frame if you could ?

I've built a few gravel bikes with the Transmission system with the CFR-505 from Carbonda.
All the riders are extremely happy!
I'm a bit jealous now, still riding the old Eagle AXS on my gravel 

The chainline of the SRAM gravel/road crankset (wide) is 47.5mm, which may cause chain rub on a couple of small sprockets if your chainstay length is on the short side (420-430mm).

I contacted SRAM to see if I could safely widen the chainline a bit. A colleague of the person who responded to me had the same issue with a mullet setup. I mentioned that the chain rub would cause some noise and lateral chain wear, but they said he was managing it fine...

I escalated the issue and eventually got someone who, after some back and forth, confirmed that SRAM has 47.5mm max only.
If I remember well, they didn't say it directly, but implied that it would be okay to use a wider chainline if found, as MTB setups allow for much more.
I added a 1mm shim on the right side, which solved the rub issue.

In addition, the app from SRAM to know the chain length, and the position of A/B setup key is not reliable.
It stops at around 38T, so add one link per additional teeth.
And it puts the setup key to A while it should generally tell B. Test both options and see which one works better.

Now, I'm about to build another one, and this time I'll try with XX1-Quarq/104BCD crankset with a 49mm chainline

Have a nice day! The warranty of our RD13 ratchet system hub is one year. There is a waterproof gasket inside the hub, so there is no problem in wet environments. As for the grease issue, all hubs require normal maintenance after being used for a period of time. I hope there will be other friends who purchase our ultra-light carbon wheelsets to complement the riding experience.

Did anyone notice Wheeltop is now advertising 3-14 speed cassette compatibility? I didn't even know 14 speed cassettes existed? Lol

14 speed is pretty outdated now, if you aren't riding 1*15 you're shooting yourself in the foot
