Miche Primato Pista Hubs


I was taking taking apart my oldest wheelset last night and this is what I found under the grime, a crack. I've had a brand new Miche track chain snap on me previously but I must admit that these hubs have served me well: three years of riding through summers and winters, racing alleycats, playing polo and whatnot, and keeping in mind that I got them in a used wheelset. Anyhow, no more Miche components for me, grazie.

Broken Profile Fixed Hub



A cone broken off somebodys' Profile Fixed Hub. And these were supposed to be some burly American-made hubs from a respected BMX brand, yeah? Ok, of course stuff sometimes breaks, especially if abused, but still this makes me wonder a bit about their design...

Velocity Chukker // Split Seam



Kyoichi's new Velocity Chukker split at the seam. And these were supposed to be some tough rims? Not like those exploding Chinese rims, right?

Quote from the man himself: "Fucking piece of shit!"

EDIT.

Just to make this more clearer and before the Velocity President Mr. John Black comes here to set me straight once again:

Everyone understands that stuff like rims can break or get damaged in certain conditions, right? One rim or whatever component breaking does not mean that every item produced by the company in question is no-good. Not even when the rim is question was marketed as a extra tough rim for 'the fixed gear tricks / bike polo community'...

Shimano Sora Crank After 20 000 Kilometers



This is what 3 years and some 20 000 kilometres of daily riding does to a crank. But maybe it should be pointed out that within the same time the owner, who is a bike messenger, broke also three frames, three front wheels and snapped off one rear hub flange.

Equipment Damage






This is what happens when you do those tricks on delicate track bikes. A dead Giro funnybike, broken Vivalo fork and some carbon fork. Be warned.

Real Taco'ed Rim

Ok, yo'all know already about the whole discussion going on all over the web about that one H+Son rim that split. I personally only want to point out that maybe you should not judge a new product entirely based on one individual defective item and incident. 

Or am I wrong in this? I guess time will tell. If more of these start popping up, then we need to re-evaluate this case but until then here's the most on the point comment I've come across yet: 

"It does look thin but that doesn't mean it's not a good rim. That was not from skidding. You hipster's getting all hard core pulling the circus/bmx tricks under some over-pass on gear designed to be used for other purposes should stop bitc*ing about it. It's pretty funny reading post's from hipsters with no mechanical or engineering background giving negative comments about gear they're misusing."


UPDATE!

Here's actually the manufacturer's response to John Prolly's blog post which he has not, yet at the time of writing this, approved to be published there:

"This is my response on the prolly blog. But I see he has yet to approve it.
I high doubt this rim snapped in half by itself causing the inner tube to be cut. I'm leaning towards the fact that it must be some outside force as you can see the sidewalls are clearly dented.

Anyways here is the response:

There has been no official H Plus Son reply as we have yet to see the rim in person.
The "official reply" that people are posting, is in fact a few weeks old, and is not a response to this rim.

Prolly the rim isn't half the weight of a Deep V, they are about the same: 580 grams.

The tire well of these rims is made to the same specs as the many other road rims we manufacture. They are 0.8, plus or minus 0.1 mm

We are a new brand. But the factory has been making rims for the past 10 years. We make about 6-7 million rims each year and about 2 million of them are double walled.

We don't want to piss anyone off, nor do we want to push responsibility onto someone else. But please we think there needs to be more investigation into the real problem of this before pushing the blame onto one party.

We have asked for the customer to send us their address and phone number and a representative will go and inspect the rim.

If for some reason the rim did not rip apart and cut open the inner tube, we believe we reserve the right to take this a step further in clearing our name"

You can see from this picture that the force of a exploding inner tube is huge. This is a posting someone else did on a different blog relating to this issue. These are mountain bike rims mind you.

"Wowza! I had some MTB Salsa Delgado rims fail the same way, although not as epically.

The outward pressure from the bead is apparently one of the strongest forces on a rim - who knew!"
