Any integrated bar/stem with something like 35 or less top with 40 or more drop? I can't find any chiner versions as of yet.

Something like the bmc bars or what I'm guessing the new enve's will be like.

i bought 5 groups at the same time. i had 4 bikes to build and i bought a spare one in case one would be dead on arrival or self destruct immediately. Built the 4 bikes, everything was fine for weeks, i then received a frame to review so i put the spare group on that. After weeks of "this stuff is wonderful", all hell started to break loose. The 2 dead RDs aren't the only problems i've had either. Had another problem yesterday i posted on the erx/9 dedicated thread.

That's an impressive failure rate.

I recall reading not to use the automotive brake cleaner on bike brake rotors because it leaves a residue that doesn't get burnt off at bike temperatures like it would on an automobile.

Good call on that. A wipe down with an alcohol based on the bike yesterday leaner afterwards would be safe

I don't get why all the hate for the frame, it's not like they're forcing anyone to buy it. Love it or hate, it even got GCN's attention. I'd say the publicity has worked in Sava's favor.

Sava has more traditional bikes in their line-up and the builds look quite respectable in terms of components and weights.

Awesome man, when are you taking delivery of yours? Looking forward to the review.

Anybody else bought the 1018? I'm considering it. Light, 32C, EPS moulding, monocoque, seller with great reputation (with the caveat that they just shipped a broken 17D to a forum member...).
For those who have one, how has it been riding? any points of comparison?

They're different companies...

Guilty :)
I stand on the shoulders of giants, nurtured by a culture of patisseries, adultery and weapons manufacturing.
And I complain. A lot. For example I thought my er9 was a piece of shit when it stopped working yesterday. Turns out I just didn't charge it. I blame al Qaeda.

LOL

You lost me. tf, is that thread fit? in the video i call his BB a PF BB because the BB isn't hold by threads like BSA / T47: the interface between the BB & the frame is smooth --> i call that PF. There is a thread between 2 halves of the PF cups, but that thread doesn't make it a threaded BB the way BSA / T47 is.
I received the Liqui Moly 3312 today, precisely so i dont have to figure out which loctite product to use and during which phase of the moon it's going to work best and whether it cured with or without a load.
Now I'm just a peasant looking for easy solutions found by people who seem to know what they're talking about.
I've never measured BB holes because i dont have the tools to make them rounder anyway, touch wood, i hope i never have to.

My bad mate!!! Didn't watch it properly!

It's a pf, but it's a thread together pf. They're a little bit obscure and are kinda inferior in theory to a single piece bb, usually only used if the bb area is weirdly shaped or obstructed that you physically can't press a single piece bb in. Are you sure you have one of those?

For this type, can grease the threads, just make sure you don't get any of the surrounding carbon where the bb will seat inside the frame. Retaining compound on the usual parts where a regular pf bb seats inside carbon area.

For retaining compound you can use 641 compound and 7649 activator. If you can literally push any side in with your hand then the hole is oversized, so use 638 instead. It should be a tight interference fit, and not be able to push it in by hand.

I do, it's the whole point of the rabbit hole. i guess you're in the camp of only morons would put any kind of grease there?

Sorry mate you said PF BBs in the post, I guess just a typo... That's a tf in the vid. I'm sure you already know this, but there is an alu insert which is pressfit and bonded into the carbon hole in the frame, which has threads on the inside, which the bb threads into. Yeah I'd use an nlgi00-2 grease or anti-seize for threaded bbs that tighten under load. I think anti-seize might make more sense here. Ones that don't tighten under load, I'd use threadlock, but that's hardly any these days.

Although, if it's a pf, like what you said, then retaining compound between the carbon and bb. Usually 641.

If yours creaks and is a pf and not tf, then you may wanna push it out and measure it up. If the hole is too small, you can hone it safely (takes about 30min to remove 0.01mm, so it's hard to overshoot it), if hole too big you can use 638 instead of 641 for retaining compound, as it'll fill a much bigger gap more betterererer.

Sometimes creaks can come from other stuff though, like chainring bolts being uncooperative, or just grit stuck between the crank arms.

It's more contentious for PF BBs, but it seems that Wakos brake protector is the ultimate product to use, as per "ride of Japan" on YT, and apparently Cannondale in mechanics workshops (I think Australia), and cannondale basically invented creaking BBs with the PF BB30. And for us in Europe, Liqui Moly 3312 (made in Germany, cheap) seems to be a legit alternative. I haven't seen anyone saying it doesnt work. Both products apparently are a silicone based grease.
But people do fight over whether loctite is good or not (& if so, which, and which cure time, and how...), and if you believe Shimano you shouldn't use anything at all, and then there are those who put regular bike grease, or lithium grease, or copper grease.

You don't mean grease between the bb and the carbon hole in the frame do you?

they got a large OEM order in 58, right?

After talking with Yishun when they delivered one of my frames, my understanding is that they do everything in batches of frames and sizes. The oem and individual orders all get put into the same batch then divided up one all are complete and the biggest orders get priority over smaller ones in terms of overall turnaround. Then they go off to paint. So if you order a frame that's not in stock and needs painting and you're an individual order, you get to be at the back of 2 queues. Like me because I got one of the yishun frames painted.

I'm sure there is more to it.

Oh, alright thanks! Another question - is it good to grease the bearing in the picture above also from the bottom/inner side?

Some people will say yes to give the bearing a little extra protection, other people will say no because grease can and will attack the epoxy in the carbon softening it over time.
