Fixed.

The red small ring has to go under the bigger red sleeve.

Hi,

I have pulled the hub appart and don't know how to bring it back together properly. Can someone help?

The freehub doesn't seem to fit closer to the hub due to the red ring which cannot be pressed futher towards the inside of the hub. Possilbe? What do you?

And yes, the spring to be put inside as well.

Many thanks, Dennis

Hi,

is this 0.7mm spacer ment to be placed like this hold in place with this 1 plastic pin?

Many thanks, D

@MF_one: Still happy with them? How many km did you do already? May I ask you about your weight? Nany thanks, Dennis

Can someone tell me why this tool doesn't fit?

in combination with

Isn't T47 = T47?



And will I need to use the 3mm spacer for a none-wide SRAM RED crank on this frame? If yes, where? Drive-side or non-drive-side?

Update: Ahh, just saw it here: https://www.sram.com/globalassets/document-hierarchy/compatibility-map/road/dub-choose-a-road-bottom-bracket-compatibility-map.pdf    I have to use it as "Outer right, drive side spacer".

Is it?

Maybe.. I do have second thoughts now about the size I ordered. I went with a 56, but I'm 183 cm tall with an 88 cm inseam.

For reference, I've ridden a size 56 Cannondale SuperSix EVO (Gen 4), slammed with 110mm stem, which fitted me perfectly and has a rider height range of 177–185 cm. When I compare that bike to the LightCarbon size 54 (rated for 180–186 cm), the LC is actually about 6 mm lower in stack and 6 mm shorter in reach.

I know the SuperSix isn't the most aggressive bike out there, but it's still a proper race bike. The LC, on the other hand, is marketed as an "endurance all-road" bike. Yet these numbers would suggest the LC is actually more aggressive than the SuperSix. That doesn't quite add up to me.

When I look at the LC size 56 instead (187–193 cm), the endurance label starts to make much more sense: similar reach, but noticeably higher stack. That geometry aligns far better with what I'd expect from an endurance-oriented frame.

The SuperSix rider height range matches my real-world fit perfectly and is also consistent with other manufacturers. So maybe LightCarbon's height chart is technically correct, and I'm just being thrown off by the "endurance" label. Still, based on the geometry alone, the LC size 56 seems to fit that category much better.

Just sharing my thoughts. Curious how others see it.

I went with size 58 now after having consulted Gemini. With 40cm handlebar, 9cm stem, seatpost without setback and will go most probalby without any spacers or at least with the minimum.

I'm 185cm with inseam 88cm.

Coming from TANTAN GR030 size 57 (gravel frame) as a 1x race bike with 28000km so far. Quite comfortable. Ok, not good looking due to 6cm spacers. 

Does someone knows a GRX 1x carbon crankset alternative with PM with titanium-alloy spindle which I could use with the same chainline?

Many thanks, Dennis

I inquired about a chrome silver into glossy raw carbon and Carol said it might be possible a few months ago. She also said top tube mounts were not possible so clearly things changed over time.

So not possible anylonger? If so, did she explained why not longer possible?

Thanks @paul_otta!

I will be installing SRAM RED Aero 1x crankset (12-speed, chainline 45,0 mm) and chainring in combination with 1x13 RED XPLR rear derailleur.

In the description of SRAM RED Aero 1x crankset I just read:

Compatibility bottom braket: SRAM DUB Wide Road

So I think I have to go with the wide version.

Can someone let me know if

SRAM bottom braket DUB | T47 85.5 mm

will fit into the frame? There is also a wide version available with spacers. Many thanks, Dennis

Jack Ding replied to me that they will have 56/58 size soon-ish.

Did someone got a frame yet?

Hi,

I think I also need your help regarding the frame size I should order. I'm 1.85m and have a insame lenght of 88 or 88.5cm.

I would opt for a 58 size. Would you agree with me? Attached a picture from bike-stats.de (size 56/58) where I have compared my current frame I'm riding as a road bike for bikepacking, TT, bike2work, etc. since about 4 years with 20000 km so far. Pretty happy with it.

I'm running my TanTan with about 5cm spacers below and a 9cm stem.

Many thanks, Dennis

Found a 1x drivetrain build on Facebook..... Looks quite nice!

Spec: 1x setup using SRAM Rival E1 brifters, SRAM Red XPLR E1 13-speed cassette and derailleur, and the Force Aero crankset with power meter.

6.9kg without pedals.

The owner is 179cm and took size 54. I'm 184cm with 88cm inside leg length and think about ordering size 58. Too large frame size?

I did a comparison with my old TanTan GR040 (s. attached picture). Looks like LightCarbon in size 58 is even smaller than my old one, possible?

Someone in the thread wrote that the rear hub/freewheel sound is quite loud - with the "own hub system" that supports carbon spokes.

Peter told me that if I want to go with carbon spokes I will have to got with their own hub system - DT Swiss, Novatec, Extralite won't work.

Can someone record and upload a video that shows the noise and share it here?

This is what I did -- FSA no55 headset + Tavelo Bar-stem + Tavelo-supplied FSA adapter/spacers. Worked great.

What I mean is that it is a b*tch to fit the nondriveside crank and spindle through the SRAM DUB T47 internal bb. This has nothing to do with the frame itself--just the way the SRAM components fit together. And yes I did need the single 3mm external driveside spacer. Given the chainstays/tire clearance it's needed for the fit on the LTK266. Now that it is set up it works perfectly. But I needed help to get it installed.

@klrdd:

Hi,

I read you post about the process of installing the BB and crankset....and about "chainstays/tire clearance".

Would love to run 1x SRAM Aero chainring at the front in combination with SRAM E1 XPLR at the back.

Any ideas about if it will fit - also with a 1x 48t chaingring a the front?

Many thanks, Dennis
