"The frame looks great, especially the rear geometry where the metrics are quite similar to Factor Sarana.

For me, the main downside is the seatpost. I prefer a round post over an aero type, which makes it easy to change to a different setback or a dropper.

Finally, I assembled my bike and had a ride.

frame and parts are following;

frameset(frame+fork+seatpost+headset bearings+hanger) : RD301-D size 54
wheelset : farsports waverim 4050 carbonspoke
tire : Schwalbe pro one
stem : fsa na smr stem 100mm -6degree
handlebar : OG-Evkin HB-010 400mm
groupset : shimano 105di2 rear 43/11
crankset : xcadey(include powermeter) 50/34, crank length 165mm
BB : praxis bb shimano T47 ib(for TREK)
pedal : wellgo mg21 flat
saddle : MIXED 7D max

Since it was my first time assembling a bike myself, I encountered several issues that made me regret buying a second-hand groupset, ultimately costing me more than if I had purchased a new one.

Additionally, there was a clearance issue between the frame and the crankset, which I resolved using spacers (1mm + 0.25mm). You can see the resulting gap between the frame and crankset in the attached video.

Apart from that particular issue, all other problems and delays were caused by my own inexperience. Nevertheless, I consider this a valuable learning experience for future bike maintenance and assembly.

Regarding the riding experience, I can't provide detailed feedback yet due to the shortened crank length (originally 170mm), roughly adjusted seat-post height, and significantly increased stack height compared to my previous bike.

But I can confidently say that it works flawlessly, and I'm sure I'll enjoy riding this bike for at least the next several years.

I understand Chinese bike in general has no serial number. Is this the case for LT as well? maybe they've some hidden serial # etched in some where. I looked, but so far can't find them.

I asked to LT bike to print serical number(or code) on the frame when I order, the reply was that there is no serial number.

I think they have batch number at least for the manufacture, but it seems they don't like to disclose it.

Hello

I ordered this frame.

Could you please share which T47BB you can recommend ?

Also does anyone know if a Magene P505 crank would fit ? Seems to be a gamble with T47 frames

thanks,

Considering the price, I Choose Praxis T47 – I.B. SHIMANO.
Magene P505 is compatible with Shimano(24mm), so it will work in your case too.

If you have extra money, you can choose change the better bearing(like NTN or ZEN) or you can go Chrisking if you are rich enough.

Because there are several BB brands, find the bb with those terms and choose based on your preference : T47 internal, shimano(24mm).

That internal BB is less than satisfying. If I recalled ( I don't have pic to shown the internal as I already build up the bike) correctly it should be smooth and no wrinkles like that. You might want to show it to Alisa first before you start the build.

Got a reply from Alisa, and here is the part;

Confirmed with our production manager , the uneven BB inside surface will not effect the safety of the riding , you don't need to worry about it . 

sooo... I will try to believe her(and the production manager).

Yep I sent email to Alisa. I will share the reply when I get.

great video! it gives a good idea.
can I ask what bag is that attached to the lid? is it a storage bag with bottle cage screw attachment? do you have a link? thanks.

It's Fidlock single toolbox(https://www.fidlock.com/consumer/en/twist-single-toolbox/09646-p00002-blk)

I can replace the box to the bidon which support fidlock system.

I unboxed the frame which had received about 3 weeks ago..

Those are my impressions

1. Paint quality is good. I worried about the actual color, but it looks pretty good.

2. finishing around mounting part is not perfect. But for me it is okay 'cause those part will be covered with bottle holders and bags.

3. Controversal down tube storage is also looks good. It felt sturdy when I held and shaked it by hand. I will test it with a bidon with full water later.

4. I didn't order the handlebar with the frame to use standard handlebar, so had ordered stem and spacers separtely. It seems not matched well with the basic head tube kit of the frame and it makes me worried...

Assembly will be done by myself, so it will take some time(hope to finish in december).

I started the assembly, and these are my impressions;

1. Bottom part of the BB seems uneven as you can see in the first pirture. I think it is okay considering that the stressed part is near the threaded part. But I cannot but feel some disappointment.

2. I think there should be a cover to seal the outlet of di2 cable which connects to the front derailier, but I couldn't find it.

3. Test for the downtube storage cover. I think it locked pretty well. Please check the video I attached.

I need more time to assemble the frame, but until now, routing the cables (both brake and Di2) is pretty easy, even though it is my first time to assemble a bike.

Hope to share the picture of fully assembled bike within this year lol.

that video shown nothing.
Try to mount a bottle cage to the cover, then insert of water bottle that's fully filled. Try insert and pull out the water bottle repeatedly to/from the cage (this is real world usage), see if the cover doesn't fell off.                                                 

See my earlier post with video that demo how easy to lost the cover.

I checked the video, and it seems like the closure system holds the cover with magnatic force only, without any mechanical closing part.

I also somewhat worried about that is this cover can hold the position with water filled bidon...

I really hope it have some kind of mechanical lock system...

Because I ordered the frame, I asked to Alisa about is my frame free from the downtube storage cover issue.

And the attached video was the answer from her.

Does it look fine?

I think moving forward 2025 and beyond this LT/Tantan will be the common platform for the "all road" genre.

Regarding 'all road' genre with the frame, it reminded me of the youtube with the post below - and makes me think about the relationship between Ribble and LT bikes:

I plan to buy the RD301 too. So far contact with Alisa has been great and she is very helpful. Here are some of the photos of their show bike (size 52). Nothing special but it's cool to see how the fully asembled frame looks like. I think it looks really good!

Another interesting thing that I found... On one of the photos, you can see (top right) the frame from Ribble? I did not know, that they are producing frames for Ribble, I've only heard about Argon.

And, the geometry comparison of the two frames(RD301-D and Ribble allroad sl r which is mentioned in the youtube) is also preeeeetty intersting - fork geometry looks almost same.

Hi, this is my first post on this website.

I am considering buying this frame and have already had a discussion with Alisa (LT Bike manager).

Everything seems good, but I didn't get a picture of the fork from her, which I need to decide whether to choose FSA ACR or SMR.

Alisa said its headset supports FSA's ACR but didn't clearly state whether it supports SMR or not.

As for me, I prefer to use semi-integrated routing (SMR system) due to my handlebar bag, which requires a round tube handlebar. Also, SMR is easier for maintenance.

So, could anyone share a picture of the fork to find out if it supports SMR?

You can check out the difference between ACR and SMR from the attached file—whether the front hydraulic hose comes from the fork's tube (ACR) or from a hole in the fork (SMR).

P.S. I think the most similar big-brand frame with this one is cervelo soloist.

Among the pictures of tantancycling FM301, I found SMR-like routing.

So, if those frames are same one, it means RC301-D also support semi internal routing..

Try to understand more on this "open mold"...

Q: One mold share by many factories? in this case the same mold used by LongTeng and TanTan? or same mold, same factory makes same frame, putting different labels?

Q: Who own the mold? multiple ownerships? How does the arrangement works if it's shared?

From my understanding, open mold means open for every factories - bought the mold(or design) from a frame design company. So it can be considered LongTeng and TanTan use identical mold (or mold's design) made form same frame design company.

I found a frame from tantan cycling, which seems identical with RD301-D.
http://tantancycling.com/index.php?_m=mod_product&_a=view&p_id=1146

So this frame seems open mold frame..
