LTK266-D-SL, race frame, 680g, <800g w/paint & metal parts (M), fits 35mm+ tires

i am assembling this frame as well, I had an issue with the top headset bearing that has a too tight fit with the frame. It is possible to install it, but it is very hard to remove, even with pleny of grease applied to the bearing outer surface. I've measured the bearings and they are 52mm outer diameter. I'm going to try it with a 51.8mm outer diameter bearing. Longteng shouldbe more precise on this kind of details, they are providing an headset that is not the best fit for the frame.

Yes, many of us -- myself included -- experienced this exact problem. Disappointing to see Longteng is still shipping low quality and/or wrong sized bearings. I had no issues once i used those provided in/with the FSA ACR no55 headset.

Didn't even use the provided bearings. DEDA bearing fits perfect.

Belatedly replaced the original seatpost clamp cover with @Sakizashi's creation. It looks great and fits very precisely, so precisely that at first I thought it didn't fit at all! If you're in the US, I encourage you to get one if you're bothered by the Longteng-supplied rubber thing. And Sakizashi's is actually cheaper (if you're in the US) than sourcing one of those old giant defy covers from ebay or ali.

I am having a look to this frame, but I realised that on size L and above, reach is really short... is that true or correct? I need a frame wiith low stack and high reach, and ready for competition (I 'd like a stiff bike). If this frame doesn't suit me, any other alternative on the aero but lightweight side?

Thanks in advance

The velobuild aero frame is very low and quite long. Lightweight, idk.

the VB one is too, agressive... this is for my son, he actually uses a spcycle r088, and I want something of this style, maybe a bit more aero, but not too much, because races near here are quite hilly.

This bike isnt super aero, but it has the most aggressive geometry Ive ever seen:

Hey everyone,

Wanted to share my build and give some feedback since I found so much useful info on this forum when researching this frame. A huge thanks to everyone who shares their builds and experiences here, it really helped me make my decisions.

Listing:

Frame: LongTeng LTK266 D SL (size XL)
Groupset: Sram Force D2 46/33 10/33 (climbing gears, obviously)
Crankset: Quarq PM (172.5mm)
Wheels: Zipp 303s
Tires: GP 5000 S TR 32 (set up with TPU)
Handlebar: Tavelo Avro Gen 1 (40x120)
Saddle: Ryet carbon
Pedals: Look Keo 2 Max (not in the photo)
Headset: FSA 55R (goes without saying at this point, but might as well mention it)
Bolts: Titanium & aluminum, Carbon-Ti
Rotors: Sram 160mm (I had enough with my rim brakes road bikes, I'm just here to stop at the bottom of the descents)

Final weight: 7.6kg with bottle cage, computer mount, and pedals.

Ordering / shipping:
Communication with the company was easy, quick and clear replies. Shipping took about 1 month. No import taxes on arrival in France.

Assembly:
Zero assembly issues. One thing to watch out for: the stock seatclamp screw is too long, swap it for a shorter one before you assemble the bike. Also need to swap the seat rail clamp bolt for a titanium one, the stock one is already rusting.

Bike feel:
Confident, but like others have said, it's honestly kind of boring (in a good way). It's good at everything, snappy enough when you are out of the saddle, just a genuinely nice bike to ride. Nothing to complain about. Feels confident downhill, helpful when you are exhausted, and keep the speed nicely. It's probably not the funniest bike to ride, but it's extremely reliable and that's what I'm looking for and light race / endurance frameset. Already 1029km on the bike since I finished the build the 7 august.

Can't wait to try the GP5000 S TR in 35mm!

Thanks again to everyone here, this forum's been a huge help!
