Is that the bike with the super narrow head tube? Looks interesting and has potential, depending on the pricing and the geometry chart.

Hi everyone, today I'm taking the TT bike out for its first ride. The build went completely smoothly. The extensions on the base bar seem a bit long to me; I'm curious to see how the bike handles. I'm still waiting on my disc wheel, so I've got my training wheels on for now. The cockpit felt a bit flexy during the initial roll-out—what do you guys think of the bike?

Looks rad. Front view picture, pretty please?

There's a few helmet threads on here. P2R and Sunrimoon should be good, I'd trust them. P2R A20 is tested by Virginia Tech as very safe: "The P2R A20 MIPS earned a 5 star rating. Its STAR value score of 8.14 ranked #10 of 308 helmets tested."

Unless I am seeing something wrong, both of those brands seem rather expensive. I'd rather get a decathlon helmet at that price point.

Has anyone else got bb creaking noise when putting power out of the saddle? What could it be?

I don't have this bike, but pretty much every time I get a creak or talk to someone else who is experience creaking that they say is from the BB, 9 times out of 10, it is not in the BB. Last time I had creaking, I removed my through axles, cleaned off the dropouts and axles, greased it, torqued it to spec and the creaking stopped.

I do get that they want to brand their frames. The problem is: Their decals / logos are ugly as hell not aesthetically pleasing. If they had a cool decal / logo design, people wouldn't even discuss this.

You want to make $300 profit on every frame? Sure, just slap that bad boy on every frame from now on:

Is that the actual logo that you found on the website, or is this something of your own creation?

Don't have much to add, but I don't think you are right about superteam wheels. The rim brake version is 25 external, but the disc brake version is 23 int / 30 external. That's pretty much perfect for a TT wheel IMO.

Thanks jonathanf2, I'm already running the 18t OSPW that came with the new cage and trying to figure out if that's what is causing the excess chain slack at when using both the smallest cog and chainring. Would love to hear if you have any experience in running a similar set up to me and whether or not you had as severe chain slack as me or if I've stuffed up the installation (either not set the derailleur spring tension correctly or if my chain is still incorrectly sized).

Thanks.

I am running an eR7 with the LTWOO original big pulley. All gear combinations work fine, there is no too much slack or tension in any extreme.

Sorry if this has been answered somewhere already, but what bearings are used in the headset? The front looks really narrow, which I really like, so I am wondering what size bearings in the headset they are using.

Lmao, what's with the handlebar penis.

AI got sloppy. My interest in this frameset is waning with each "render" they put out.

Those "renders" are hilariously bad - the model and the instagram post don't even appear to match. The model has an integrated riser bar, while the bike from the post has a regular one piece cockpit. The model looks cool, but the fact that they willingly post AI slop without even bothering to check for 2 seconds whether that picture even appears to be the same bike, does not inspire a lot of confidence.

I do like the look of it in the model, but I would be wary of it.

and as i said, same mold as the ican tt017

Same mold - sure - but the weights are very different

Well I've just gone back to Daniel ant  and specifically checked this with him because of your post.
He's adamant that the RF01 is manufactured by Longteng and says the factory designation is LTK266-D, with the FK266 fork.

I've been speaking to Daniel at Light Cycling this morning and managed to clarify a bit more about where the various frames they sell are actually coming from.

Daniel has a direct relationship with Longteng and has confirmed that several of Light Cycling's existing open-mould frames are manufactured by them. Specifically, he says the RF01, RF02, RF04 and GF09 are Longteng frames.

He's also shown me a recent delivery note from Huizhou Longteng Sports Equipment Co., Ltd. showing frames, handlebars and components being supplied to him, so there clearly is a genuine commercial relationship between Light Cycling and Longteng.

However, I specifically asked him about the new RF10, and he has confirmed that the RF10 is NOT manufactured by Longteng.

The RF10 comes from another factory. This is particularly interesting because, as I understand it, the same underlying frame is also being sold by TanTan as the X68, which is why I was interested in finding out who the actual manufacturer behind the mould is rather than simply which companies are selling it.

I asked Daniel directly who the factory is. He has said that, because the RF10 is currently a new product and he has invested quite a lot into bringing it to market, he would prefer not to disclose the factory at this stage to avoid creating any unnecessary issues.

That's fair enough, and obviously I'm going to respect that rather than start guessing.

It does highlight something that comes up repeatedly with Chinese open-mould frames, though. We often know the companies selling a particular frame, but that doesn't necessarily tell us who is actually manufacturing it. The same mould can appear through several different sellers, and tracing it back to the actual factory can be surprisingly difficult.

To Daniel's credit, he's been quite open with me about Light Cycling's business model. He doesn't claim that all the frames on the Light Cycling website are their own proprietary designs or that Light Cycling manufactures them. A number are existing open-mould frames sourced from established factories, including the Longteng models above.

So at least we now know one thing definitively from Daniel: RF01, RF02, RF04 and GF09 are sourced from Longteng; RF10 is not.

As for exactly which factory is behind the RF10/X68, Daniel wants to keep that commercially confidential for the moment, so I'll respect that.

Have we confirmed for sure that the new TT-X86 and this frame share the mold? These two bikes, while similar, don't appear to be identical. The headtubes and forks are for sure different. They do both seem to be... inspired by the SL9, but I wouldn't go as far as to say they come from the same mold. It might be the different sizing of the frames on the pictures, but it is hard to gauge

I think the QuickPro TT:ONE is currently the lightest TT bike with UDH to come out from China. I could easily be wrong though, would be happy to find something else myself.

I am actually relieved they kept the steerer straight, I think there is a lot of room for something to go wrong with the wonky steerer and I would prefer tantan to stay out of it.

If that deal is real, I am picking up a frame. For that kind of money, I am down to keep it as a spare frame in case I crash my current bike.
