Frame looks good, and thorough overview!

I’m currently speccing out groupset for my order - am looking at SRAM Force AXS E which is direct mount UDH, I know there was some confusion earlier in the thread about the bike having ‘mini UDH’ hanger. I think in the end it was decided that this was just a lightweight version of the hanger itself? The direct mount derailleur should fit fine?

Also interested to know if the LightCarbon BB is any good or whether its worth spending more on a 'decent' one, either OEM SRAM (about £30) or another 3rd party version?

I now have put a few hours of riding into the LCR018-D so just want to give everyone the final specs of the bike and a quick initial impression.

Specification:

Size 54 frameset
Raw carbon, gloss finish, laser silver decals (absolutely superb - despite my love of hyper chameleon finishes, this raw carbon is by far my favourite finish).
380/80 Handlebar
Inline Seatpost
Ultegra 8170 Groupset with titanium bolt upgrades on the groupset and throughout the bike
Frames & Gear UDH Direct Mount Hanger
CeramicSpeed T47 BB
Go-Zone 45mm Carbon Wheelset, 24mm internal, CX Ray Spokes, brass rainbow nipples, GP5000 30mm Tyres, Ridenow TPU tubes
Galfer Wave Rotors, Swissstop 34RS brake pads
YBN S12 TIC rainbow chain, waxed with Dynamic Wander Wax (soon to be moving to UFO Ultra Endurance Wax)
Lightcarbon 3D print saddle and carbon bottle cages
Lightcarbon titanium garmin mount

Assembly:

Putting the bike together was a pleasure - has to go down as the easiest bike I have ever built - and this is my first disc brake bike so that is saying something!
Everything is finished to a very high standard, no problem routing any cables - handlebars are easy to route through as well - everything just works.
Di2 battery holder in the seatpost is custom made to fit and is a really nice finishing touch.
Another feature not really mentioned is the little GoPro mount which attaches to the Garmin mount in where the mount meets the bar - not out front at the actual Garmin faceplate. This is such a great little addition - it allows me to add a light to the bike but keep it nicely tucked in close to the frame - so compact and neat and not something ive seen before, so kudos to LightCarbon for this!

Initial Impressions:

If there is one word I would use to describe this bike, it would be smooth.
It's exactly as I hoped for, and exactly the bike I wanted.
Is it as responsive as a TCR? No. Is it as fast as an Aeroad? No. Dont get me wrong, its fun and a pleasure to ride, but im trying to give an objective feel of the actual ride compared to some other bikes.
BUT - its smoother than anything else ive ridden, and im willing to bet I might actually be faster over 4-5 hours on this bike than the other 2 listed, because this bike does not beat me up at all.
It is so easy on the body that after 2 hours I find myself physically in far better shape than I would be on any of my other race bikes - and thats the key.
I bought this bike for endurance, and it's ticking all the boxes - and then some.

I went for Ultegra 8170 Di2 and ive never been as blown away by a groupset.
I've been using 9150 Di2 on my Cervelo S3 which is very, very good - but this 8170 is ridiculous. Absolutely silent and shifts faster than any groupset ive ever used - even the front shifts feel like a rear shift - so smooth, fast and quiet.
I wasn't expecting that much of a difference - but it is a big difference to any groupset ive used and I couldn't recommend highly enough.
Ive added the little button "exaggerators" that slip in under the hoods to make the hidden buttons more pronounced (I got them off Aliexpress) - what a difference they make! I can press even with winter gloves and feel the clicks so clearly - a small but massive improvement.

Another big motivator for this bike was the shift to disc brakes - I have hand and wrist problems at the minute and needed something to ease the pressure and force going through my hands - especially on wet winter roads.
Overall, I am delighted with disc braking. Bleeding the 8170 was so simple as to be a joke - took 5 minutes to do both front and back. Aligning the rotors did keep me busy for half an hour as I wrapped my head around it, but now all set and silent.
 
I was surprised by the gradual nature of the braking - to me it feels much like a very well setup rim brake bike, but the key difference being that it feels the same even in the wet! So this is a huge improvement.
Im using Swissstop 34RS pads, so maybe other pads would give a different feel, but I am very happy with how these perform.

Another interesting bonus is the lack of external cables. The bike looks so sleek and clean - and to that point, no cables makes cleaning down the bike SO much easier!
It is such a well rounded package overall, so smooth, confidence inspiring in its stability, still agile and absolutely silent, which always brings a smile to my face when riding.

One point to mention is the handlebars. I love the look of the design, and the sloping shape gives an extra few mm of height to the shifters. However that sloping shape is not great for riding on the tops as it angles your shoulders in towards each other and feels rather cramped. As someone who loves to climb, I can see this being a slight point of annoyance in the future, so I may revisit the bars after a while and think about changing them out. Its a small point, but something worth mentioning.

It will be interesting to see when the good weather comes around again what I think of taking my Cervleo S3 out again - the LCR018-D is such a well rounded bike that covers every scenario so well, that I can see it becoming my go-to bike for most rides.

Future Plans:

There's not much more to do to the bike, but I have a couple of things i'd like to try.

1. A "best" wheel upgrade for the good days. A 50/55 ish deep set of wheels around 1200g to really make the bike shine. The Go Zones are great, and the brass nipples give me all year round confidence, but at 1380g they are a do it all workhorse. Id love a set of all out performance wheels for big days out. I'm trying to decide between DFS Carbon custom build, Serenade 50mm, Aero Raptor 50mm, XM Carbon custom build, or 9Velo - any thoughts here much appreciated!

2. A second fork. I have my current fork cut with a couple of extra spacers for maximum comfort, I'd love to get another one and cut it slammed for better aero performance on fast days. Its not that big a deal to switch the fork out, so currently debating the cost if an extra fork and an extra caliper.

Sorry for the rambling, hope this is of some use to users on the forum. Anything else you'd like to know about the bike, just reach out and I'd be glad to help.

A quick question for someone who has a frame in hand.
Can you tell me the thickness (hight) of the bearing cap / spacer please. I’m trying to work out the frame stack with any mandatory spacers needed.

Thank you

Morning,

Im getting a measurement of exactly 10mm for the bearing cap.
Do you know if any spacers are needed above that to run safely?
Im considering a more racy position as a second option and having it slammed down to the bearing cap would be the best fit for that.

POTOOOOOOOO

Excellent, thank you.

I guessed at 10mm but wanted to be sure.

I still haven’t ordered a frame as im deliberating between a 52 and 54. 54 gives me more toe clearance but the stack is too high, even with another bar and -10 integrated stem.

There should be no reason why the bar can’t sit directly on top of the bearing cap. It’s the only mandatory interface needed.

Great looking bike. Glad you’re enjoying it

Thx, this is absolutely useful for me — so thank you for the rambling! ;-)
Really nice build.

I ordered a 56 cm as well, with raw carbon and a mix of glossy and matte finish with custom decals.
Still have to wait until January to receive the frame, so in the meantime I’m wandering around the forums getting inspired by great builds like yours.

For my build, I ordered a wheelset from XM Carbon Speed:
CS-D50CU-33 in the front and CS-D65CU-33 in the rear — a mullet setup with 50 mm front and 65 mm rear, and 26 mm internal width.
Since I’m a heavier rider at around 95 kg, Peter advised me to choose the T800 carbon, 20/20H pattern, the titanium-colored Carbon Speed hub, and the 3.8 mm carbon spokes because they’re a bit thicker and stiffer than the 5.0 mm version.
Peter just sent me the first photos of the rims. Total weight is 1335 grams.
If you’re interested, I can give you an update once I receive the wheels.

I have a couple of questions:

• Which titanium bolts did you use for the groupset?
Do you have a list with quantities and sizes? I’d love to order them before the frame arrives.

• And just out of curiosity — what’s the total weight of your bike? Did you measure it?

No problem, weight wise, I think the bike weighed in at 7.3kg including Dura Ace pedals. I'll try and weigh again at the weekend to double check this.

Bolts are as follows:

Really? Don't you have to bleed the brakes?

Bleeding the front brakes while building the bike took about 2 minutes.
I know I was well prepared and had got proper tools from bleedkit.com, but couldn’t get over how simple and quick it was.
I do think the 8170 groupset is very easy in comparison to some stories of other groupsets.
Wouldn’t bother me in the slightest to have to change the fork.

I’m waiting for my new frame to arrive, and in the meantime I bought an Ultegra Di2 groupset from AliExpress. I know this is slightly off-topic, but following this chat I understood there are many experts here I’d like a quick opinion. The shifters don’t power on at all, even after replacing the batteries, and I’m starting to think they might not actually be the wireless ST-R8170 levers I ordered. The mechanism inside also looks mechanical. If anyone can tell me more from the photos— or share any tricks to test them, I’d really appreciate it.

I’m not an expert, look for these:
Was the battery you changed in the lever/housing?  Me h levers don’t have a battery.
Is there a place to install a shifter cable?  Electronic don’t have a shifter cable.
ADo the shift buttons connect mechanically to the shift drum in the body, or are they contact switches, possibly with a visible wire running back into the body.  In the first case mechanical, in the second electronic.

It is the right model. Yes, it is a LED. Try to keep pushing on the same time both buttons (level up and level down speed button) and the LED will light on).

Connect up the rear and front derailleurs to the battery, download the eTube app, and follow all the prompts to connect to them + the shifters, and you'll see everything's in working order.

Are there 2x10mm and 2x5mm spacers or only one of each?

I think two of each.  I originally ordered an extra 5 & 10.  Then I decided to order a second handlebar in order to play with fitting.  So I got two bags of bits with a total 5 10mm and 5 5mm.  Which I think reflects 2 of each per handlebar and my original 1 extra of each.
