New frame: Longteng RD301-D

[Dan S.]

Dumb question incoming: does anyone know what the heck this is?

Seems to me like the Di2 cable clip from your RD.

Seems to me like the Di2 cable clip from your RD.

Thanks, you’re right. The clip slides in but doesn’t seem be held in place - it feels like it can fall off pretty easily, or am I doing it wrong?

It is normal that it moves around its axle.

I got my 301D (54cm) delivered! I'll attach pictures as I go through the build. Quick initial question: the headset I got through longteng included a crown race and/or pressing ring. The fork appears to have an integrated crown race, and a quick, dry install indicated it didn't need one. Also, a video posted here from the Longteng factory had the workers putting a crown race on a fork. What do you all think?

For those asking about zero seatpost. Here's the measurements of the seatpost:
front view: 26mm
side view: 45.5mm

not a very common measurements as far as I know. But check out this Ali ad:
https://www.aliexpress.us/item/3256807058255216.html
look at the SP045 seatpost, at least one of the measurement matched, you need to confirm with the seller about the side measurement and whether it's zero offset (looks like it could be).

Wishing you luck finding one on Ali....

Hi

Has anyone find a zero offset seatpost to match this frame design ? Desperately looking for one as Tantan does not make it.
Thanks,

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.

How is the frame quality? One of the other posters said that his mechanic noticed that the top tube carbon is soft to the touch in places..??! That really scared me off this frame. I'm 105kg I can't be having the frame fold up on me because it's soft in places.!

Factor came out with the new Monza, reminded me of the LT RD301 as soon as I saw it! Looks a bit more aero than the LT RD301 though.

Integrated storage seems to be picking up steam. Any other Chinese frames with integrated storage?

Hey guys,

I'm stuck between the Tantan FM301 (looks like this one) and the GR201 gravel bike.
I've mostly ridden full-suspension MTBs, so I'm not sure which would be best. I won't be riding trails, but I'll be on quite a few unpaved roads. I figure with the wide tire clearance, these bikes should be good for that, right?
Also, any other tall riders out there? I'm 195cm (6'4") and worried a 58cm frame might still be too small. Thoughts?

Light carbon new release for anyone interested

Depends on your liking, just one comment: I am not sure why they call it 58cm frame - no measure on this frame is 58cm.
Seat tube is 553, do your math or compare against your bike if seat post extension is enough for you.
Reach 394, Stack 588 - I consider the stack on the lower end, but it depends how much saddle to bar drop you can or want to tolerate.

I wonder how microsuspension works with those chunky chainstays. I remember back in the day when microsuspension was a thing on XC bikes like orbea oiz and cannondale scalpel they used paper-thin chainstays and it actually did work. On this frame it just looks like a gimmick and a potential failure point.

Thank you! I guess i have to find someone with a similar bike to test.
Can't really compare my current Geometry, since i ride enduro/trail bikes.

Can anyone really confirm, that low profile 40mm tires fit?

I current have 40s on my 301. Will post a longer post shortly.

I am exited for your review. This is currently my favorite and I think I will oder it within the next few days, unless you have some mayor downsides. The only thing I am worried about is the frame being too small, but 58 already is the largest size.
