VeloBuild VB-R-268 frame

[Tilmanstoa5ty]

Oh we have the same bb. I also ordered ztto like that. But since my last ztto bb (bsa) on my mtb didn't last that long really, I'm inclined to using good ol' shimano plastic one. I really am not sure yet. Will decide on the spot I think.

Tell me, how do you find the bb shell quality, tolerances etc...? I haven't worked with pressfit shells, only bsa. Seems pf bb's have higher tendency for creak development. Also, did you use any grease?

Since this is my first bike build i can't really tell you much about the bottom bracket as i lack experience to compare it. I did some research about grease and there seem to be multiple opinions. Some people (for example hambini) recommend using some loctite (not the one used for screws) others use normal grease. I'll be using this silicone stuff recommended by some people on bikewrench reddit. Will see how the bb will hold up and if it will develop any creaks.

Cutting it would be my first step but since these things are probably pretty cheap i will just go for an alternative if i fuck it up.

I have the bottom bracket from the attached pic and there are two rubber o-rings on the area that touches the frame to protect it.

I've been using the same BB from ZTTO as well and really like the screw in aspect. They are fairly delicate, in that if you don't use the correct tool and instead use a clamp wrench for example like I did once because I didn't have two BB wrenches, one for each side, you can crush it pretty easily and the bearings won't turn anymore.


Been using regular grease myself when installing and seems fine.

Thanks for the input! I will take it into consideration when I go for the bb install. How do you find the bearing durabillity? Or simply, how long is your installed, and how many km's is on it?

I'm kind of sucker for shimano I admit, but it's because, really, all of their stuff I found durable AF. I mean, their cheapest bb i have now on my indoor trainer bike, is like, 4 years old, and still spins without noise and any noticable friction. My first spd pedals are, well, unbreakable. So many rock hits and crashes.. That damn thing doesn't give 2 f?cks about it. So that's the only reason I'm inclined on pressing the plastic Shimano bb into this build.

I would highly recommend to get some sort of "cup style" (first attachment) bottom bracket tool to install the screw in bottom bracket. I got myself two of these cheap ones (second attachment) and it's really hard to get a good grip on the thin area of the bottom bracket. I think these tools are better suited for bsa bottom brackets with a much larger area to grip.

@volan: If you already have the tool and the bottom bracket i think there's nothing wrong with the shimano bb. The sole reason for me to go with the screw together was the lack of a pressfit tool.

I have two simple tools like the second photo you showed. And I gues it will be more simple to use pressfit tool with shimano. I got one pretty cheap on aliex, and it looks just fine.

[Tilmanstoa5ty]

I would go for the pressfit in that case

I personally like the screw in/out aspect about it the most. Agree that a cup style tool would be favourable but the cheaper thiner tool works as well

[Tilmanstoa5ty]

Here's another build update from me. First about the bottom bracket: I wrote earlier that i would recommend a cup style tool as i couldn't get it in with these cheap tools. Seems like it was my fault. I unscrewed the bb again and redid it and it worked flawless. Seems like i cross threaded the bb in the first try and therefore couldn't get it to work. On my second try it worked even with the cheap tools. Everything else went really flawless so far. Given that this is my first build i expected tons of problems i would have to figure out but so far there are none. I installed the di2 and the cranks. I also cut down the steerer tube a little further and removed some spacers. I already did a test ride on the trainer and everything worked like it should. Adjusting the shifting was very easy. The only steps missing now are cutting the brake hoses to length and installing them and aligning the brake calipers. Then i just gotta finish it off by applying bartape and i'm done. Wouldn't have expected that to be honest. Just gotta get some road bike shoes so my gravel bike can have its pedals back.

[Tilmanstoa5ty]

One day and a horrible bartape job later it's finally done. Took it for a very short first test ride. Aligning the brake calipers wasn't a problem actually. No weird sounds or creaks during riding so far. Hopefully the headset will hold up and there won't be any play on that part. I had some headset play before the ride. Retightened everything and now after the ride there's no play. Hope it will stay that way. Very happy about this whole journey so far.

If anybody has a nice idea for some decals/stickers i would love to hear about them. I would like to stick to the black and white scheme but would like to spice it up a little.

How's the front ring shift quality for you with those Magene chainrings? Mine is suboptimal at times, but once I went back to Shimano chainrings the shift quality has been superb. My guess is the "ramps" on the back side of the chainrings aren't as pronounced as Shimano.

Had no issues so far but it was only a 20 minute test ride with almost no elevation. But whenever i shifted in the front it did without any issues on the trainer and outdoors. Hopefully i'll be able to do a longer ride in the following days. I live in a hilly area so there will be lot of shifts on the front. Will let you know how that will go.

Patty, I think for most users Shimano chainrings are anyway laying around and if not they’re quite cheap to get. I run them with the Magene crank and there’s literally 0 difference vs the full shimano crank combo in terms of shift quality. In other words, I don’t see the argument for non Shimano chainrings… Just two cents….

I mounted the ZTTO screwed in my gravel bike and in my VBR099 (replacing a shimano DA...) and it works flawlessly. It's a bit tricky to disassembly because once you unscrew one side, the other stay in place but you can gently hammer with a rubber mallet and it comes out.

I would reccomend the steel ball bearing instead of ceramic due to durability

Frame arrived. Managed to assemble everything and do a quick test ride. Everything seems ok with the frame, paint is really nicely done, although I'm on the edge about durabillity/quality. While I was pounding the pf shimano bb out of the bottom bracket shell (ill explain why), rear calliper was loose by the chainstays, and it rubbed againt the frame while I was pounding the bb, only to realize it scratched the paint there... So yea.

I meassured the diameter of the bb shell and it was around 40.6mm. I was keen on pressing in the shimano plastic bb, but after I pressed it in and inserted the spindle, shell pressed the bearings so tight so that spindle wasn't exactly spining like it should. I got used to BSA bb's, and spining cranks on it was always really smooth. Here, they simply wouldn't spin at all, so I immediately took them out and put in the threaded/PF bb from ztto. It sits flush and seems ok, will order another one as a replacement. I think VB could do with 0,2mm wider bb shell.

Build:
L size icebreak red paint
420/110 vb handlebars
105 di2 shifters/brakes/rd and fd
riro carbon cranks
"Peter's wheels" 26 iw, 50 deep
contis gp5k s tr

Build ended on 7.7-8 kg with pedals and bottle cages. Happy with the result. Although I, of course, made a mistake when cutting the forst steerer. I used to cutting mtb alu steerers and when I assembled the fork, caps, spacers and stem --- I didn't put in the fREAKING expander plug when I marked the cut... So the steerer sits pretty much flush with the stem, therefore - 0.5cm f??king spacer now sits on top, instead of the VB top cap. I don't want to dissasemble everything now because of it. I did order another set of spacers which didn't arrive (don't know why, asked Chris), so I will put one under the stem when it arrives and fix that problem.

Nice build. I ordered the same paint but in your pics looks like orange ice brake paint. I suppose that it's your phone camera effect.
