I am interested in this frame, but have sent two inquiries through the website and gotten zero replies. What is the best way to get a price quote on one of these frames?

You can contact Alisa directly: longtengalisa@163.com.  She handles sales and is usually very responsive.

Never use the contact form of the website. I tried that with different manufacturers and it never worked, even if the website would say "message sent" or something :D most have mail adresses or QQ or Skype contacts somewhere on their website.

I did get mine.  When I tracked delivery of the package, the first one got stopped by CN customs, so Alisa sent another one.  Somehow, now I have both packages lol, so maybe check the tracking.  I ended up getting delivery in about 3 weeks after all that.

Btw they do have a saddle clamp for oval carbon rails.  But you can also find oval adapters on Aliexpress - the saddle clamp is the same as what I believe is the Ritchey one-bolt clamp, and those can be found in several different sizes on Aliexpress.

Now I can finally build the bike, yessssss!

So do we have any build or review of this frame?

finally received the missing parts: seatpost wedge and rubber cover. Gave them to mechanic this morning. But got a call later about some missing parts on the headset spacers... sigh... >:(

here's the problem, maybe some of you know how to resolve...

Send this to Alisa:

"handlebar are sold together with frameset from LongTeng.
Problem: The spacers from the handlebar and the spacers from the headset has different dimensions size and they are not match together. See attached pics, as you can see the 2 small knobs: the headset spacer one is measured 37.xx on the two small knobs and the handlebars spacers is measured 34.xx, as a results the handlebar cannot be joined to the headset due the both spacers dimensions are different.

手把的垫片尺寸和龙头 headset 垫片的尺寸配不上 手把无法安装。

Just want to confirm if you’re sending the right spacers for the handlebar that will worked with the frame headsets?"

Fingers crossed, I should be picking up the bike from my LBS in the the next 36 hours. I plan to have a chat w the mechanic who built it and get his take on frame quality, any issues he encountered, etc. 

I hope I didn't just jinx meself with that...

What handlebar are you using for the build? I hope you've better luck on the headset and handlebar spacers.

I ordered Kocevlo integrated bars off of Aliexpress because LT didn't have the 380/10 that I was looking for. (I do think headset bits and pieces are somewhat standard so hopefully a good mechanic should be able to find solutions.)

LT seems to know my issue and they make a video on how to resolve it.

Required to grind off the 2 small knobs using dremel tools.

See video here:

Here it is, at last!

I picked up the bike last night from the LBS and spoke to the mechanic who built it up.  His take:

- Overall, it was easy to build

- No major issues, nothing was mis-aligned, BB fit was perfect

- Frame quality seems to be good with clean internals

- It didn’t feel all that different from building up major brand bikes

A few other notes:

- The bike was built with Ultegra 8170 Di2 groupset, Elitewheels Edge Ultralight 45s, Kocevlo integrated bars, GP5000 tires, RideNow TPU tubes

- Measured weight: 7.4 kg without pedals (7.65 kg with pedals) – I didn’t go full weight weenie, so there’s probably still room to take that down, but it’s not a priority for me

- I put on 32s and you can see from the pics that there’s plenty of tire clearance, probably room for more than the stated max clearance of 38

- The downtube internal storage is a bit finicky to close – there’s not a solid click to close, and I need to be careful to get everything aligned to close it, otherwise it comes off pretty easily.  Once it’s closed correctly, it feels solid. I’ll have to take it for a few rides to see if it’s problematic

- This is one of those frames with a soft top tube where you can press it down with your thumb – the mechanic said that it’s no different from some of the other lightweight frames that he has built, but you shouldn’t sit on the top tube at the stop light or tryna look cool

- The mechanic pointed out that there is a bit of play in the rear wheel – if you push on the wheel from the side, you can feel a bit of looseness; he tightened up everything but it’s still there, he said it’s probably something internal to the hub, it shouldn’t impact the ride, but I’m going to follow up with Elitewheels on this

- I took it for a short spin last night to bed the brakes and there was no seat tube slippage, although it was only a 30 minute spin over smooth surfaces. (I did end up with a flat…  I’m not very heavy and rarely flat, I think I’ve flatted maybe 3 times over 15 years, so I guess it’s Mazel Tov!)

The weather here has been crap (typhoon just came through, another incoming), so I may not be able to ride much on the new steed. Once I do, I’ll come back with some initial ride impressions (and au naturel pics).

Cheers.

Nice build, I am becoming more and more interested in this as an all-purpose bike!

Speaking of tire clearance, would you be able to provide a picture/ measurement of the rear clearance down by the chainstays as well? That's usually the tight spot so would be great to see. Also, what's the measured width of your 32c tires at present?

Cheers

I don’t have calipers for exact measurements but hopefully these pics will help. The rim internal width is 22, and it looks like the 32s are 32 when inflated.

There’s been a bunch of content recently from folks like Nero on “all road” bikes like the Enve Melee and Ribble Allroad, which is interesting because I think this frame fits in that category: not an aggressive racing geometry, but not upright like endurance bikes - it sits in the middle where comfort and speed intersect. With a bit of room for rough pavement / light gravel. That’s exactly what I’m looking for, let’s see how this thing actually rides when the weather cooperates.
