I took off the chain and measured it as precise as I could using both a digital caliper, and a ruler.

Weird. Well, at least it will be easy for you to name the bike.











Chitty Chitty Bang Bang. :p

That sound is normal. I don't think I have ever not heard that noise when my head is a few inches from the wheel.

Thanks, yea it rides great so I don't think it's an issue.

Looks great!

I always have a special place in my heart for light blue bikes with silver components. :love:

Nice bike! Nice photos too.

You know what the noise sounds like to me? A derailleur that's slightly off ... which, of course, you don't have. So I'd be checking to make sure the chain isn't rubbing on something and, when you find it isn't, just lube it up like hell then ride the living daylights out of it. You'll probably find the noise'll go away eventually, even if it's when you replace the (eventually) knackered chain.

Still a good looking bike. Sure you're not just looking for flies in the icing on your cake?

Very nice build!

I like you how you ran dummy cable under the tape on the left side.

Ok So I have a new problem that might be a big one, and also the source of the noise. This morning while exploring more, I noticed that the rear wheel has a small amount of play. Let me explain: if I grab the top of the wheel and move it left and right, there is a small amount of wiggle. It is definitely apparent. When the wheel is spinning, there is also a small amount of wiggle. This is odd to me for two reasons: the hubs are brand new, and the wheels/rims were dished and trued! Lastly, it appears that the axle is properly held in place by the nuts. Thus the only thing I can think of is the rear hub/axle. But I don't know if I should open a can of worms and disassemble the hub, or take it to a LBS, or contact velomine where I purchased the hubs.


:mad:

Chain is on backwards too (inverted). :)

She's pretty, clean build.

That's probably the main cause of the noisy drivetrain. I'll bet it will quiet down a lot when the chain is installed properly.

Who built the wheels? Maybe you could take it to them to see if perhaps something was loosened and not put back properly when they were assembling your wheels. If you built them yourself, maybe take them in to your LBS and see if they can determine the problem.

How much movement are you finding? Like, tenths of millimeters or full centimeters? Not that either is okay, I'm just sort of interested in how severe the issue is and am wondering if when the wheels were trued/dished if something didn't get put back correctly (or if something was damaged in the building/truing/dishing process).

Update:

I took the rear wheel off, and adjusted the hub and now the wiggle/play is completely gone. However I did notice something else. The wabi track ends are supposed to be 120mm, however I measured it to be 121 mm. I wonder if this is normal or cause for concern.

On another note, the wheel doesn't seem to be spinning cleanly, and doesn't seem like it's true.

Here is a video:


:bang:
I just corrected that.

Oddly enough, I installed the chain correctly and the noise is still present! :(

I ordered these from Velomine.com. The movement was tenths of millimeters, not even apparent visually, just by feel.

nice

I can see the wobble in the video, but I can't tell if the wheel (rim) is untrue of if that is just an imperfect tire. FWIW, I have never had a perfect tire. Gotta Put something next to the rim, (a zip tie fastened to a stay will do the trick) to inspect the WHEEL for trueness.

You might inspect the tire mounting too. Make sure it is uniformly seated all the way around, on both sides.

The 121mm spacing is a NON issue.

Edit to add: I don't care what Hairnet says (:p) that thing sounds like it has a low quality, poorly maintained, unlubed derailleur on it. That noise would distract me to the point of crashing. :lol:

Sideplay won't cause any noise, and a tiny amount is no big deal. If the hub bearings are adjustable, then the sideplay can be removed, but I'd rather have a small amount of sideplay than bearings that are too tight. The "wiggle" may or may not be related to the apparent hub play.

Let's eliminate an over tensioned chain. Rotate the cranks until you find the tightest part of the chain. Then adjust it to where there is some visible slack/weep. Not a ton, but enough so it is free to bounce up and down when you raise the rear wheel off the ground a few inches and drop it. IME an over tight chain doesn't make the exact sound that yours is making, but it definitely makes it noisey.

I did the trick you told me and it does appear that the rim is true.

The tire does seem to be seated pretty well, but I don't think it's a perfect tire.

Now to the sound. Trust me, this sound is bothering me too. Here are some more bits of info that I have explored.

1) With the chain off there is ZERO sound, it's silent.

2) With no chain, the wheel spins forever and there is no wobble, thus I don't think the bearings are binding, or a hub issue.

3) I was worried the chain was defective, so I through on a brand new KMC z410, and it had basically the same noise.


There is no more hub play. Thus I am wondering what would cause the tire to wiggle. Is it possible the axle is bent?

I have played with the chain tension 50 times probably and nothing changes the sound.

Last idea I have. Swap cogs with a known quality cog of a different brand. Stumped.

I'm stumped on the wheel movement as well... I was thinking it might be something to do with the axle or maybe it just wasn't seated properly when it was all put together/built. But maybe it's just a faulty hub. I'd contact Velomine and see about getting a replacement sent in. Perhaps you can order a new one and then send the old one back for a refund. If you do it that way, you can maybe compare the new hub with the old one to determine if it's faulty. Although the front one isn't doing it so maybe it is just a faulty hub.

As for SquidPuppet's suggestion, he seems to know his stuff. And he never lies, you can tell by his nose :D. I'm actually getting ready to swap out my BB/Crank and rear cog on my Masi as mine is making a weird noise as well (I think it's the BB, but I want a new Crank and Rear Cog anyway). Maybe try swapping some stuff one at a time and see where you're able to eliminate the sound.

I think I figured out the problem, tell me what you think.

I deflated the rear tire a significant amount, and I can tell that the wire bead is not properly seated in some areas (i.e. when I squeeze the tire I can see a gap between the tire bead and the rim side wall). Do you think this could be causing the wobble?

If so, should I just take it to a LBS to have it seated?

EDIT: Thinking about just getting this Park Tool PTS-1, because if I change tubes or anything i'll probably have the same issue with this tire/rim combination.

Decrease tire pressure and use your hands to push/pull the tire into place. If it's giving you trouble then check that the rim strip is centered on the rim and not obstructing the tire. A poorly seated tire is really obvious with a vertical "hop" as the wheel spins.
