New frame: Longteng RD301-D

[jeffrey]

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,

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.

Would be really great, if anyone could try if a standard 40mm (gravel) tire would fit. For example a Conti speed or schwalbe g-one. If it fits, it would give this frame so much versatility....

I would be shocked if a low profile 40 didn’t fit. Someone earlier in the thread took pictures of rudimentary clearance measurements. That being said, 40 would likely be tight for wet/muddy days.

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.

My rear wheel play issue is related to the wheel hub bearings. I've the YuanAn wheelset, YuanAn agreed to sent me new bearings. So it's most likely unrelated to the frameset. We'll see after I received them from YuanAn if it resolved the play issue.

Have you tried a different wheel? Does that eliminate the play?

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.

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.
