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!

Did someone find a radar mount? I tried a Giant Defy mount but it doesn't fit.

Hi Everyone!

Finally making my first post after reading every single post in this forum before I built my ltk266-d-sl bike. Thank you all for your contributions! Now, to the components on my bike:

Frame: ltk266-d-sl size Small naked UD black glossy finish

Group set: Ultegra di2 12 speed components, 52/36t chain rings and 165mm crank arms

Rotors: Dura ace 160mm front and back (160mm riderace rotor adapter in rear)

Cassettes: Ultegra 11t-30t (road) and 11t-34t (gravel)

Headset: FSA No. 55R 1.5” ACR LS (fit beautifully without issues - highly suggest getting the LS version)

Saddle: Ryet Ultimate 3D printed carbon

Wheels and tires: Princeton Carbonworks wake 6560 strada with 30mm GP 5000 S TR (road)
Tukus Evolution 50mm depth super light at 1100 grams with 36mm Tufo Thundero HD (gravel)

Pedals: Xpedo CXR red

Bottle cages: ZTTO ultralight aluminum alloy

Bottom bracket: Ryet Senicx ceramic bottom bracket

Di2 battery holder: largest shimano one at 21 to 29mm

Handlebars: LightCarbon HBR17 90mm x 400mm with 8mm rise fully integrated

Regarding the handlebars, LightCarbon has an option where you can purchase their handlebars with the FSA adapter and I’ve had zero issues with fitting or anything. I used the HBR17 spacers that came with the handlebars.

With the gravel wheel set, the complete bike with pedals weighs about 7.2 kg and with the road wheelset, complete bike with pedals weighs 7.5 kg. Running both tire sets tubeless I am still using the provided thru-axles and have not shopped around for a different pair. However, I did change out the seat post bolt for a M5 x 30mm bolt. This is a much better option that the proprietary one provided.

Alisa was very helpful during the ordering process. Took just over a month for the frame set to be delivered.

Overall, I’m very happy with the bike and love how it flies on compact gravel. With the 11-34t cassette, there is a rhythm disruption with my cadence between the middle gears which should be resolved when I replace the 11-34t with a 11-30t cassette. Gravel tires are 37.5 WAM, and I can fit a 4mm hex key between the tire and frame in the rear. There is about 1mm of space between the knobby tire and the FD wire.

My plan is to have a more relaxed, endurance setup (hence the 40mm of spacers) and I still feel great after riding 2.5 + hours in the saddle. Nonetheless, this will be my primary compact gravel bike. I love how lightweight the bike is and it is much faster uphill than my specialized roubaix sl8. I am still waiting on my XMCS VRT frame to arrive and that’ll be my road bike. FWIW, the XMCS VRT has practically identical geometry with the ltk266-d-sl size small. I’m 5’7” with an inseam of 31.5” and arm length of 19” and this is the best fit I’ve had for a bike yet.
