New frame: Longteng RD301-D

[BeR]

Sorry, what is "TA" ?

Thru axle I guess.

Well done! make sure you put helicopter tape / clear protection tape on the frame where you have that strap for the top tube box, otherwise your paint WILL be eaten away, and the paint job will quicly look awful (been there, done that...)
And while i dont understand how that down tube box would need a strap to keep it locked, consider using a large bit of helicopter tape to wrap all around, so it's closed shut, and invisible. But obviously it'd mean you can't open it anymore.

Or an unpainted box, i think the problem here is the paint...

Long Teng now blamed the excessive paint on the edge of the cover  and downtube that prevent the cover to be locked securely, want me to use a rasp to grind off the excessive paint on the edge along the cover and the downtube opening

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?

[kwantani]

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...

There is a clasp, in addition to the magnet. But the clasp is not well designed and doesn’t inspire a lot of confidence.  Like I said, it takes some fiddling and pushing and pressing to make sure the cover is closed securely.  I’ve also found that if you stuff the storage with too much stuff, to the point where the internal sock presses up against the cover, the closure gets more finicky.

This is something that Longteng can easily fix with a better closure system, and would be disappointing if they don’t TBH.

Do you think 28mm tires would like weird on this frame, given the wide clearance?

and another question, which rotor size are required without adapters? Is it 160 front and 140 rear?

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).

This frame is super intriguing but I'm struggling with the Trek headtube lol. Does the frame look... good/fast in person? I know it's subjective, but does it pass the vibe check? Also is there a tangible ridge down the center of the seatpost?

Yes there is a ridge down the seat post.

As far as looks, yeah this is completely subjective but here is my completely subjective take: it does look "fast" because of its aero profile which is the same/similar profile of just about any other aero optimized frame: over-sized tubes, dropped seat stays, sloping top tube and an exposed aero seat post, and especially if you go for an integrated cockpit with narrow bars, disc brakes and deeper rims.  But does it look "good"?  I'm less of a fan of the kitchen counter-top wide downtube, and am more into more classic looking frames with reasonably sized oval tubes. So that's why my next project is probably going to be something more Crux and Aethos like, or maybe even a Chinese Ti frame.

Hi everyone

What would be the difference between Tantan and longteng on this 301 execution ? This is open mold but is the carbon layup the same as well ?

Thanks,

[Dragos]

I am wondering if anyone who has the bike has tried 40mm tires or would think that 40mm tires would fit

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.

Have we seen yet any full build with all the issues sorted out? I think rear wheel play hasn't been sorted out yet. It's putting me off buying this frame.
