New frame: Longteng RD301-D

[Chamomile]

Hello road people. I'm just occasionally browsing frames in here.
I'm kinda concerned about BB. It's a bit unclear from pics, but it seems that the BB is made of two thin and narrow separate hubs with thread (similar to "Factor Ostro"). Alignment can be a problem, sure, but I'm more worried about the reliability of such an approach. I'm not familiar with T47 BB road frames, so unsure if this's a common practice among chinese manufacturers and if the whole structure can hold under lots of load in a continuous manner.
So, I wonder if this construction is somewhat reliable or if there're any failure statistics already.

The T47 is the lastest standard and, from what I hear, universaly praised. The alloy inlets make it way easier for the hole to be round and in spec, than with pressfit aproaches. Also, it is large and acomodates for bigger bearings. It is one of the many pros for that farmeset, imo.

[Chamomile]

Yes, I understand and have no problems with T47 as a standard, it's a good improvement.
I'm worried about mounting these small aluminum pieces in this particular (and some similar) case within a carbon matrix. Even fancy brands had problems with a proper adhesion between aluminum and carbon, and here, the contact surface is even smaller (compared to the most common bulky one-piece insert approach), and it's chinese (with quite random QC) manufacturing.

It looks rather narrow, thats true. Only time will tell, I guess.

I am more concerned about the longevity of the closing machanism of the downtube latch. It has to hold the momentum of a waterbottle. Any opinions on that, anyone?

Here is a short video on opening and closing the latch: https://youtu.be/Kc6TbN95QW8?si=rJybJezpOjw5A6xx

I believe the Trek Domane and Specialized Diverge also have the latch underneath the downtube water bottle - I've never used these bikes but from what I can tell, these latches seem pretty solid.  The latch on my 301 doesn't close with a very satisfying click, but I'll come back here and post my experience on the road, after I get it built up.

Awesome! Thank you very much! Really looking forward to whatever content you produce with this.

Pretty happy to see this was not a reply to OralMaster

Thank you people for sharing experience with this frame.

What kind of hardware is included? two axles, rear hangar for sure. what about headset and spacer?

This is what I paid:

- US$530 for frame, fork & seat post (includes one additional color to base black)

- US$12 for headset

- US$25 for front and rear axles

- US$6 for spare rear hanger (UDH)

mine is in the LBS waiting to be build up.

Hi,
How do you like the quality of the headset, axles, UDH? Aren't the axles very heavy?
Maybe it's better to buy them separately?

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.

I built 2 268. SMR. Having built 9 such chinese bikes, i'm yet to see the ACR system on any of them.
I would get Alisa to confirm though.

It seems quite optimistic.

Thank you and please share the result when you receive.

I had this same question for Alisa and she confirmed that the 301D is compatible with the FSA ACR stem

[PANW]

I’m not sure, I didn’t ask any additional questions about it after her answer and decided to look at different frame options for other reasons.
