Carol was my contact.


There is absolutely no consistency in the responses, which is my concern.
I was told a 42t would be the largest, which I know is incorrect. I also know a 54t with a 45mm chain line is unlikely to be possible.

Regarding UDH. They’ve modified the hanger which is ok, but it sounds like they’ve also slimmed down the frame which would necessitate a spacer for the rear mech to attach.

If that’s the case, it would need to be precise as there are no adjustments on the UDH rear mechs. They don’t have High/Low or B.

I’m just not convinced by any of the technical information they’re currently providing.
If the CL value is greater than 45mm, the chainring can be more than 42T, like CL 47mm, the max chainring can be 54T

Re: Lightcarbon: LCR018-D (endurance all-road) Also if anyone is interested and have access to 3dprinter, here is my design for Garmin Varia rigid holder specific to LCR018-D seatpost profile.

Big thanks to Jim from LightCarbon, he was able to sent me seatpost profile drawing in high res and thanks to that he saved me a lot of time in CAD and measuring. I think that was pretty awesome from LightCarbon.

Only thing you will need is M3 hexagon nut (there is a little cut out in holder where do you slot or push in m3 nut) and M3x20mm bolt, puck and puck bolts you can use the ones from original Varia mount.

I also recommend to use at least 3 wall loop and 25% infill (just to be sure just print it with 100% infill, it increases weight for just 2g :) ) in slicer, and PETG material for increased temperature and UV resistance.

Re: Lightcarbon: LCR018-D (endurance all-road) Finally my build is complete.
Pretty happy with results, I think it looks pretty sweet. I hope I get it fully try out on the road tomorrow. I hope that it rides as good as it looks :).

Size 58, 400x130mm handlebars specs, without internal storage version
Saddle height on photos (bb-top of saddle) 820mm (another 2cm available to min insertion line), drop between saddle and top of handlebars is 10.5cm with 15mm of spacers.

Weight is 8.5kg with pedals, varia radar and elemnt bolt (like it is on photos) witch is something like 300g lighter than my Aeroad with same config, I doubt I will be able to feel that, but that was pleasant surprise

Those logos on rims and frame are made out of reflective material so it has nice "glowing" effect out on sun.

Re: Lightcarbon: LCR018-D (endurance all-road) My frame arrived, it was perfectly packaged, and everything was in perfect condition. Everything is exactly as I ordered, with a significantly higher quality finish and, above all, a superior paint job. It's difficult to photograph and looks even better and very elegant in person. It's not exactly lightweight... with the paint job, 56cm frame, and storage compartment, it weighs 1190g. But that's fine by me. The fork weighs 460g, the handlebars 315g (380/100), and the seatpost 180g.

I'm very excited to see how the finished build looks. I would have found assembly instructions for, say, the headset helpful. Wendy doesn't offer anything like that. Otherwise, as I mentioned before, I had a pleasant and professional exchange with her. Incidentally, I specifically requested photos after completion. The storage compartment is fantastic; it's easy to use and very secure. From my current perspective, I wholeheartedly recommend a Lightcarbon frame!

Re: Lightcarbon: LCR018-D (endurance all-road) I got pictures of a finished frame, but they had selected the wrong frame to paint.. I ordered lightest possible without storage, but this frame had storage. So if anyone wants a 47cm with storage box and gray decals, it might be available for shipping fast. I’ll wait for the correct frame. Happy about the look, though.

Re: Lightcarbon: LCR018-D (endurance all-road) Another thing that is good to know about. I was pulling my hair out why it is not working during my build for hours. I wanted to have one 5mm spacer above Light Carbon HBR17 handlebar for some potential future handlebar height adjustments, but when I did put normal round spacer above my stem headset was preloaded just on one side and headset topcap started to rub frame.
Then I figure out top face of handlebars is not completely straight and perpendicular to steerer tube. So I had to printed out my own headset spacer with 2mm angled surface and now it works perfectly.

Iam not saying that is good or bad just "non-standard" and a thing to be aware of if you need adjust your handlebar height.
Original topcap that comes with a handlebars works perfectly out of a box it is just when you need to adjust your handlebar height and put some spacers above handlebars.

I think you will need this angled spacer if you will ever need to adjust your cockpit height and put some spacers above stem, because I have no idea how to do that with stock parts without custom printed spacer.

Hope that helps someone.

Re: Lightcarbon: LCR018-D (endurance all-road) Happy New Year! (The date has already changed here in Japan)

The frame arrived at the end of November, and I built it up in early December. Since then, I've enjoyed a couple of weekend rides on it.

My previous bike was a 2008 Scott CR1 Team, so this was my first time assembling a disc‑brake road bike. But by following Shimano's dealer manual and some bike‑shop YouTube videos, I was able to complete the build without any confusion. Of course, I also referred to LC's videos and zealot128's videos—thank you for those.
Before assembly, I checked the inside of the frame with an endoscope, and it was very clean with no burrs.

The ride quality is excellent. Not too soft, not too stiff—neither boring nor punishing. It hits a perfect balance for me. The wheels certainly help, but cruising at around 40 kph feels easy, and I can really sense the aerodynamic efficiency. With my previous bike, riding into a headwind sometimes made me not want to ride at all, but with the LCR018‑D, I still feel like going out even when it's windy.
The paintwork is also fantastic.

My only personal complaint is the seat clamp. As others have mentioned, it's difficult to tighten with a preset‑type torque wrench. So I've ended up using the beam‑type torque wrench that came with my wife's Canyon Ultimate. Even with Finish Line Fiber Grip and tightening it to 7 8 Nm, the seatpost still slips about 5 mm after a ride.
(There was no problem if I tightened it to 8Nm.)

That said, I'm very satisfied overall. I had my friends test‑ride it as well, and it was very well received. I plan to take good care of this bike.
Wishing everyone great rides ahead!

By the way, someone here was looking for titanium replacement thru‑axles—did you ever find any? I've been searching as well but haven't had any luck. The LC ones are already light enough, so I'm thinking I might just order another set while they're still available.

Re: Lightcarbon: LCR018-D (endurance all-road) Build went great. Weight: 7.1kg

Size 50 unpainted (~60-120 grit from the factory).
Derailleurs, Shifters, Calipers: Sram Rival E1
Crankset: Sram Red D1 165, 35/48
Cassette: 11-36 Ali
Rotors: Shimano Dura Ace
Wheelset: XMCS CS-D50CU-36, 16/18 5mm bladed
Tires: GP5000 S TR 32c for the weighin and testing. Installing Michelin Pro 5 TLR next week
Stem: 100mm Aliexpress -17deg
Bars: Lambda X Wing
Pedals: Speedplay Comp w/ J&L Spindles
Seat: Westbiking Carbon Saddle. 

Eddy current gauged to find the areas with thick resin (>20 mils) and sanded down to 5 mils & 400 grit. Recleared matte equivalent to SWorks RTP frames I've fondled. Frame and Fork weights through the process respectively: 972 -> 948 -> 953. 424-> 418 -> 421.

I can probably get to 6.9kg refinishing to raw carbon and cutting the seatpost, going from sealant to tpu tubes, and installing a tiny cassette, but it probably ceases being an all road, all climbs, long distance tank of a bike.

LIGHTCARBON waterslide decals are different logos than everyone else has LOL.
Didnt have tape and hoods installed for the picture since I was replacing them due to a crash on the previous bike. They're present for the weigh-in.

Ported over all the hardware from my Winspace T1550. Pedaling and sprint stiffness visibly higher when looking down riding on the trainer - as expected since the T1550 is a T800 carbon noodle bike. No other differences of note at equivalent saddle and bar positions.

I love the storage size and its no-bag aesthetic outcomes for the bike. My reference for in-bike storage is canyon endurace which is l insultingly small.

I’d be astounded if a Cycplus As2 Ultra didn’t fit. I’ll check when my frames delivered.
Or someone can guesstimate if they can be bothered 65mm (Length) x 47.5mm (Width) x 28mm (Height)

It fits, but not when in the frame bag. It also needs to be halfway in the opening; otherwise, the front lip of the cover can not get under the carbon, and the hinge can not be closed.

Re: Lightcarbon: LCR018-D (endurance all-road) I finished my build last night. Size 58 with SRAM Force E1 and 9Velo LV Wide wheels with 32mm GP5000 S TR. I am 185cm tall with a 86cm inseam and I was torn between size 56 and 58, but I compared the geometry with my current bike and the size 58 with a 120mm stem matched the closest. I've been fitted in the past on my old bike and I am quite happy with the fit. I am running 2x 10mm spacers on the new bike, so I have room to lower the bars in the future if need be. I don't have a proper hanging scale, but I estimated about 18lbs total with a bathroom scale. I inspected the frame with a borescope before I built it up and it looked very clean. I'm happy with the paint as well, it is a variation on the Eurobike paint scheme with the marble red paint and matte black.

This was my first full build from the frame up and it went smoothly. The brake hose routing was a little tedious, but it wasn't too bad. I just used a small pick to guide the hose through the fork and bars. The brake mounts and bottom bracket areas were super clean and I didn't have any alignment issues at all. Like others have said, the saddle clamp is a little fiddly, but I added some carbon paste to the clamp and it seems to be holding just fine.

I haven't had the daylight to go for a real ride yet, but the quick spin around the block was promising. This is my first new bike since riding my 2014 CAAD 10 rim brake bike for the last decade+, so I'm sure it will be a massive upgrade for me.
