Lightcarbon: New LCR017-D (or Yishun R1058-D)

[cucumber19]

Build is complete! Thunderstorms and normal life are preventing the first ride but I think we are good to go! ... Except some front derailleur run which I will get into in a minute. 

So far as the build, the only "crappy" bit was the threading on the derailleur hanger was unsmooth, but not unusable by any means.  For the "normal crappy" I think it should be obligatory to tip our caps to the mechanics who have to deal with integrated cockpits on the daily ... chapeau!

So, 2 problems:

1. The BB provided by LightCarbon is fine, except there are no spacers included with it.  Would have been nice to know ahead of time.  You have been warned

2. Front derailleur alignment.  I can't seem to turn the Sram Axis Rival (normal, not wide) FD far enough so it's in line with the chainrings, pretty much ensuring chain rub on the smallest cogs while in the big ring.  Any tricks people here can share?  I'm kinda leaning toward grinding down one side of the curved washer to allow a little more clearance, anyone think of a reason this is a fundamentally terrible idea?  I think even .25-.5mm on the inside edge should be enough for me to line things up.  If it matters, I ended up using a single 4.5mm spacer on the drive side, wasn't able to get close to lining things up, and there really isn't enough clearance with the frame without any spacers drive-side.

Let me know what you think of the build, and if you have some suggestions about the FD, I'm all ears!

Thanks!

I would definitely think about getting a brand name bottom bracket like wheels manufacturing.  The BB gets the brunt if the torque and you want it to have some longevity

[cucumber19]

Well, I’ll start with getting the right bottom bracket … while continuing to be driven nuts by the fact that nothing is adjusting right, I notice the printing on the bb: BB3047. It’s a 30mm damn bottom bracket! Off to the LBS tomorrow! At least they only charged me $10 for the damn thing!

Mechanically I think you can grind the FD washers if it can fix your issue. As long as there is plenty of material around the bolt hole still, the bolt should be able to spread the force and do its thing. Careful not to change the shape of the washer while grinding it, because that might then cause other alignment problems.

I bought and assembled a cheap (13€) BB from Zitto from AliExpress. Thought about testing it and if it is bad replacing it with something more expensive.

My problem was, that the T47 BBs are pretty rare in the german shops and also very expensive.

So far the quality of the Zitto BB is seems great! The bearing felt good and the cranks are spinning very, very free and well. Also no play in the crank/BB so far.

So cheap must not be bad. But I only have like 300km on the bike yet.

Cheap isn’t necessarily bad… isn’t that why we’re all here?

Hahahaha...spot on!  I still prefer shimano over Ltwoo groupsets

[Stoemper]

dont over complicate it. the T47 standard makes mounting the cups that hold the bearings very easy and assures good alignment. The bearings them selfs have some quality differences but certainly not 200 euros worth of difference.

I went with Praxis. its way better then the elvedes BB that besides not fitting didnt have any trace of grease. These come with some loctite on the thread and pre aplied grease for the axle. I got them for 50 euro's at a local bikeshop. but i see online they can be found for even less like this german based webshop: https://www.bike24.nl/producten/272474?source=SBP&indexName=production_SEARCH_INDEX_NL&objectId=272474&queryId=b9d792503aa25b7f4d3d7200318231ba&userToken=3f2f54e6-6ae2-413c-ac9e-ff96baa5b254

Now I have a problem with my frame.

I wanted to give it a good clean after yesterday's ride. But I am not able to remove the back wheel.

The axle is kinda stuck somewhere. It is turning freely, the threads in the derailleur hanger are fine. The wheel itself is moving on the axle. But still I'm not able to remove the axle from the frame. Never hat such an issue.

I can reassemble it and everything is fine. Just can't get the axle out. I've even tried WD-40 and tapping the axle with a wooden stick and soft hammer.

Anyone got an idea what is the problem here?

Is it still in the thread? If it is not then the only way is brute force it out. Possibly the axle is bend?

No, it is not threaded anymore. I can even push the rear stays away from each other.

I've tried to hammer it with some Force. But the axle is not moving to the non drive side.

I think that if the axle is bend, I would face problems while riding?

[Stoemper]

Dunno I don’t see how it could be. But if you can unscrew it the rest of the way is through the wheel axel and that should be smooth bushing.

Yes, that is what I'm thinking too. I don't understand it to be honest. Maybe the fit on the non driver side for the head of the axle is to firm, so the axle head has gone into the carbon.
I really don't know ans don't understand why I can't tap it out.

Try loosening the set screw on the rear dropout before removing the rear axle

[DiabloMiles]

I also have the problem. Now i lossen the rear axle 2-3 rotations and hit the non drive side rear stay once. Then i can unsrew the axle. The head/washer gets stuck in the carbon cutout.

Second problem is the water in the frame after a ride in the rain.
I will drill a hole under the BB to drain the water. Until now i drain the water with the rear derailleur hole. Last time it was 150ml of water. The water even damaged the BB bearings.
