You are right - I posted the wrong video (it was the 268 frame instead of the 301).  I've removed the video and added 2 photos from Longteng of the real 301 frame which match up what they have in the brochure: https://imgur.com/a/XvH327j.  Sorry about the mix up.

Here are some updates from my communication with them:

- Quoted price of US$450 for frame, fork, seat post

- They can offer for additional charge: integrated handlebar $80, headset $12, through axle $30/pair, spare rear hanger $6/pcs

- 980g +/-40 for size 52 frame

- Zero offset seat post is not available

- Available 45 days from payment

I've had some discussions with them around custom frame painting:

- US$85 for 3 colors

- They can do custom decals (which will sit underneath the final coat of paint), but for simple stuff, they will make it part of the frame painting instead of doing decal stickers - they prefer to get vector files instead of helping with design

- They can do (or, at least they are wiling to try...) fairly complex paint jobs, unlike other sellers I've talked to - for example, I asked if they can do something like the Bahrain team bike kit from 2023 (https://www.ridemedia.com.au/racing/pro-bikes-2023-bahrain-victorious-and-merida-a-mechanics-perspective/), and they said it should be ok as long as they are provided with detailed sketches/instructions; I'm just relaying what they said and have no idea about the actual end product, although the paint jobs I saw at the Taipei Bike Show looked pretty nice

Again, sorry about posting the wrong video  :o

Thanks for posting the right pictures. Looks like its on their website now: https://www.ltbikes.com/index/products/view/id/401.html

This is the frame i have been looking for! Thanks OP!

If i end up really liking the super narrow 35cm bars I plan to experiment with I might get the 52cm, otherwise the 50cm with a 120 -6 stem would be perfect and slammed would give me the same stack and reach as my roadie.

33
Does this geometry work? This takes more than 40C easily.

Yeah it does. Twitter gravel?

34
This is definitely an interesting design. I will say that more than seatpost flex, i would love the option to have a road bike geometry that could fit 35mm tires in a pinch like the Enve Melee, even if its optimized for a 30mm tire. This design clearly would have space at the seat stays, but the fork and the chainstay would be the limitation. If this bike does have that kind of clearance. Consider me interested!

I do question the seat tube cluster design as it seems like it would limit the range of height adjustment that can be done, but another big question for me is how much dirt and water would foul up the seatpost clamp area since its placed so low and close to the tire.

35
Did you end up buying something? curious if you got the LTK266. I have a place in the mountains, i'm tempted to get one to build something light w 32C tyres. Where i live is pancake flat, i got a LTK268 and I love it (1k km only though).

I didn't.

I have nearly all of the build components. I decided to have a handlebar developed as the final piece, put out an RFP for it, decided the cost of the mold was too much and then heard that one of the factories wanted to make a bar to 90% of the spec I wanted once the new UCI rules were implemented. I then provided feedback to help shape the design. So long story short, going to keep waiting to see what is out there until i can get a couple of sets of those bars. If i were to pull the trigger today, I would get a Carbonda size S /51 505SL and stick a 130mm S works -12 stem on it. I have worked out a 3d printed headset cover to make that setup work.

36
I don't have this frame, but I have that stem and have a lot of familiarity with headset bearings.

If the frame is ACR spec, all you should need is the No. 55R headset. The SMR stem will come with split spacers and both that hose guide pictured and if you want to go full internal, a transition spacer that is designed for routing through the stem.

37
For the base frame, the going rate seems to be $870USD on sale and just over $1000USD regular price. Definitely compared to the regular price Panda Podium seems to have pretty decent pricing since they include shipping for $1199USD

The Team version though is just over $1200USD so their $1668USD asking price seems comparatively expensive.

That said, looks like a pretty nice frame if you are willing to live with less tire clearance. For weight comparison if the weights are accurate, this Team frame just over 100g heavier than than an S Works Aethos and should be lighter than a regular Aethos. Its designed for internal cable routing too which add a bit of weight. Pretty incredible for the price.

38
You can see the photos of the windtunnel testing setup here: https://imgur.com/INTX8Ca

It seems pretty basic. Wheels handlebar and frame that's it. It was made fun of because its so basic, but that basic testing in the tunnel is about a lot more than marketing; it should be part of the development process to get real data that confirms the models they are using to develop the bike; the same way that you test to confirm the results of FEA. Sharing the pictures and the plots IS marketing since the results are likely to be not very representative to a rider. Ideally, they would have also tested rider interactions and had components attached to the bike, but that is yet another level of complexity and a different run of testing, which would add additional cost.

However, saying that the process to validate models was done at all is a sign of a more mature engineering process. To me thats a big deal and huge step towards closing the gap to big brands.

39
I would avoid Seka just on the basis of their customer service and revolving door of european distributors. That said their hype was driven by the RDC being made in the same factory with the same tech (allegedly) as the Factor bikes. It was one of the first light weight chinese bikes to see the light of day in western markets. As the story developed though it was undone by a brand story that didnt quite add up (i.e., an "aero" bike with an endurance geo that never saw a wind tunnel), atrocious delays and customer service, and issues with details like seatpost fitment. While I personally dont worry too much about the pictures of cracked frames, those other issues are big enough for me to not pay that much for an RDC.

I agree with @patlean1 that the Elilee is a more complete story as a light weight race bike that was tested in the windtunnel (albeit slower than the SL7) and with decent reviews. However in the current market without discounting, that frame is also a tough sell. Afterall you can pick up a complete Pinarello F5 105 Di2 in the blue color for $3280 from Excel Sports right now.

I have another build in the way first, but I am planning on a Carbonda 505SL for this kind of thing (1x fast commuter with room for those ultralight fenders, or 35mm tires with mud clearance for some lite gravel). I have a more serious gravel race rig for longer days in the saddle and tougher terrain.

My issue with the 707 is that its very gravel endurance focused with the stack too high and the steering too slack to make a great race rig for the pointy-ish end of gravel races, let alone fast road riding.

Yes. Though its really difficult to check and verify. XACD does 0.9-0.7-0.9, but some straight gauge bikes not built in China are 0.7 and therefore end up lighter.

I just ran across a version of what i think is this frame and it looks like being marketed as having 35mm tire clearance. Curious to know your thoughts on if there is space for tires that big and if we are talking 6mm of clearance on all size, 4mm, or less.

43
Just based on numbers on the geometry chart alone, I am a huge fan of the Voice Velo. This is another bike I would buy but wont because of overlap and the budget being eaten by custom ti bikes. I also think if the seatpost, routing and stem are nice enough its actually not a terrible price if the quality and the weight specs hold up to the press. The issue is lack of service and brand presence, but UDH and round seatpost take care of a good number of those problems.

Nice frame, but the stack is so low. It is a pity chinese manufacturers only aim for such low stack bikes nowadays. It really pulls me off the market ...

This is pushing me towards Chinese bikes. As a smaller rider I barely fit on most brand's race bikes without needing to size down to the smallest size because the stacks have gotten so tall. On gravel bikes its darn near impossible with most brands. I think there has been an interesting effect with the rise of youtubers and youtube fitters and some of their obsessions with saddle to bar drop at the cost of reduced reach causing people to size down. I see guys over 5'11" to 6ft tall on the same size bikes the pro women are racing on at 5'4" but with a stack of spacers and a 140mm stem. Meanwhile short guys like me needed the -12 degree 110mm stem slammed to fit on the SL7 and it was the only major bike brand bike that I could fit on at a size 52 because it was the only one that regular customers could get the pro level stem for. I ended up going the chinese Ti route in the long term for my road bike instead, but I am in the middle of surveyed proportions for a male of my height with "above average" hip mobility. Nothing crazy just 5'6" / 169cm.

Hello,

I bought a Canyon Aeroad some time ago. I am now looking for a handlebar for a mid-distance triathlon to which I can quickly and easily attach aerobars.

The following points are important to me:

- classic lower handlebars / road bike handlebars
- quick and easy attachment of aerobars
- integrated cable routing
- aerodynamically shaped

I have already found a handlebar from Cube that meets my requirements. However, I find it very expensive at just under € 500. (https://www.cube.eu/cube-basebar-stem-combination-litening-aero-tt-cockpit-system/ceb9cd81d29004abc773b475b8c8012c)

Is there perhaps something cheaper from China?

Thank you very much.

Is it a current gen Aeroad? If so, not sure you can make anything not from Canyon fit as they have that proprietary carbon quill design.

I wanted to do the same thing and I saw this :
https://fr.aliexpress.com/item/1005006306712381.html

I didn't buy it because I don't trust it. I am looking for buying lightweight alloy stem and alloy handlebar with carbon aerobar instead. However I have to find an internal cables stem compatible with my washers.

The reviews for this product arent encouraging. I have the "original" J bend version of Vision 4d MAS system bar on my gravel bike and if you arent looking for a ton of flare its a fantastic bar. The aero attachments lack angle adjustment but they are otherwise excellent. They were / are a stock item on the Cannondale System Six so bike shops may have the base bar available as a new take off for really cheap which is how i got mine.

Road Bike Frames, Wheels & Components / Re: Adapt bikes AT-B01
« on: February 04, 2024, 11:06:14 AM »
This is the AT-B02 that a lot of us have been discussing that is the black / carbon bike on their Facebook Page: http://www.adapt-bikes.com/Products-detail?product_id=100

They also recently added the QX-B01 which appears to be the 3D printed prototype on their facebook page. Its almost like a mashup (in a good way) between their Aero FM49 and the AT-B01 but electronic drivetrain only with the same clearance and BB specs as the existing models: http://www.adapt-bikes.com/Products-detail?product_id=95

The New 2024 Aero is not a model i had seen before. It appears to be a variant of the AT-B02 with a deeper headtube and downtube with a countersunk headset cap: http://www.adapt-bikes.com/Products-detail?product_id=101. The rendering shows UDH, but it’s not listed in the specs as they only list t47.
