Re: Carbonda Gravel Carbon frame CFR707 Took the bike out on one of my favorite loops. Feels awesome! Great traction on steep climbs with loose dirt. Really zippy and comfy.

Some more frame specs:

Headset: IS52/28.6 | IS52/40 (I'm using a Ritchey comp cartridge headset: https://www.bike24.com/p2106612.html, https://www.bike24.com/p2510554.html)
Rear axle: 173mm M12*P1.5*L15 (carbonda's weighs 40g)
Front axle: 120mm M12*P1.5*L14 (carbonda's weighs 29g)

Seatpost wedge: 36g (I torqued to 5Nm + carbon paste around the part of the seatpost that contacts the round section of the seattube).
The seatpost head is a nice design, but definitely torque those bolts well (I went up to 8Nm with some loctite. They are mounted upside down. On my first ride I probably didn't tighten them enough and they came loose, but everything staid in place.)

Re: Lightcarbon: New LCR017-D (or Yishun R1058-D) Thanks for everyone's feedback, there is definitely a crack.

I am in contact with Wendy from LC. I will keep you updated with how this goes.

Looks very nice  :D

Did you have the chance to ride it. If yes, how does it feel so far? Any problems?

Looking forward to get my frame and wheels.

Thank you.

The complete process of ordering with specifying paint, parts, and building has been a no issue (and pleasant) adventure so far.
Some really minor things are;
Tracking of the frame, a notice of a booked parcel and then nothing for 20days, and the last 1-2 days were packed with updates. Not a product quality issue.
Next minor notice, and im being quite picky now, is that the rear axle threads in place somewhat with resistance.
Hunch is that derallieur hanger and axle thread tolerances are not the same as the carbon parts.
To be honest, those are just small farts in a storm as comparison.

Did a initial 60min ride and pushed it a bit.
Im about 82-84kgs, Pmax of 1300w roughly on a super light frame, size 56 and my reaction is undisputed happiness.
Frame feels stiff and as per geometry of frame, right on target.
 
For a safety check of handlebar + stem check, I hanged my whole body wheight on the drops and jumped/rocked up and down. Solid as can be.

To summorize so far, _really_ satisfied.

You will drive at more than 40km/h with this frame without any problem and maintain this speed. Concerning the wall, I confirm the thinness under the pressure of the hand. It reminds me of my Hyper wheels (Winspace), very thin too.

While I don't really understand the squared design of the downtube, I can not imagine that an average rider would feel any difference. Especially because I guess the front wheel will make the bigger difference in that area and It should kinda shield parts of the downtube from the air flow.

I think the rider position, clothing, ... will make the biggest difference in aerodynamics.

we know for a fact that rider & clothing matter more than the bike itself, it's about 80% rider and 20% bike, afaik.
That being said, a bus shaped tube is a bus shaped tube. Even without a wind tunnel, we know that tear drop / kamm tail shaped things are more aero than round things, or boxes... And we know that buses aren't aero. You wont find an aero frame with a wide, boxy shape like that, nor will you find a frame that touts its aero prowess with a boxy shape like that - until proven otherwise, ofc. Given it's an ultra light frame, and making frames of that weight at this price point is a new phenomenon, and that LC doesn't make any aero claims, i think it's safe to assume it's not aero. Whether it matters or not is subjective. But even if it "only" costs 5W at 45kmh, i try to spend my money diligently, and given how incredibly hard it is for me to raise my ftp by 5W, if i'm going to buy a frame, and if i can, i'm going to avoid buying one that screams "i'm a bus". It's a guesstimate. It's also an aesthetics consideration, as i dont find that boxy shape appealing.

As long as we all know what we are getting/building/taking, get support and are all happy that's all it matters ;)

Opinions will always be opinions :) Being it Hambini and all other (pseudo) specialists.

People spend more time online reading all the details and micro-details than actually riding the bike and enjoying the fresh air :).

Re: Carbonda 505SL Integrated Stem Here's a new build with a mulet with the new SRAM Red shfiters/brakes - GX Transmission derailleur - X0 Transmission cassette and chain
And the Lexon gravel bar https://www.aliexpress.com/item/1005004788375665.html which is very nice and stiff

To have a better chainline (49mm instead of the road limited to 47.5mm) I did put a non boost MTB crankset.
So there was no more rubbing of the chain.

The setup app is limited to 38T, so with this 44T I did add 6 links(inner+outer) to the 118 advised.
But had to remove one after testing.

From two other builds, for better shifting, the setup key had to be set on B even if the app was saying A.
But not on this one. So the setup app is not really accurate for mullet builds.

Edit: I forgot the wheels, these are the WR40 from lightbicycle with their carbon aero spokes + ceramic hub v2.0

Re: Lightcarbon: New LCR017-D (or Yishun R1058-D) Finally got my frame today! Looks really nice. Very little if any overspray anywhere, and almost all the threads were clean (a little burring on the through axle/hanger threads).

Now to build … one oversight on my part: SRAM DUB spacers?  Anyone else get this frame with the t47 bb supplied by light carbon? According to SRAM for road chain line, it requires 1 3mm spacer on the non drive side. Has this been others’ experience?  Thanks in advance for any help there.

Here are some early pics of the frame. The racing green is just a great color, and the decals are nice and clean. There’s some “noise” from imperfect masking between the green and pearl white in a couple places but nothing anyone other than me or you all might notice!


Next post will be with the full build … think I have everything except the spacers, and some damping foam for the internal hoses. Think I will also do another layer of clear coat before really building it … any pics with parts are just slapped together, didn’t even grease any threads! The horror, I know!

I dropped it off at the bicycle shop yesterday. The head mechanic was off and they open on again on Tuesday so I left it there. I’ll get back when I get their assessment.

Well this was interesting the shop which i was always pretty happy with called me with their assessment, the thread was wrongly milled, it was undeep and in the wrong direction and then asked if it chinese and then refused even though they had the gear to attempt any repair. While picking up the frame i got another remark about trash chinese frames. Back home i send over some video en photo's to light carbon and they simply said its done by cnc it cant be the wrong direction. I was kind of annoyed but then decided to make another video while retracing the thread to show it was in the wrong direction and while doing this i found out the thread was in the right direction... then did the same with the elvedes cups and low and behold these "dutch quality" pieces of crap where both right threaded. I went to another local bike shop (the previous shop lost a customer after the last encounter) and picked up a praxis T47 BB. And yep it fits and goes right in.
