However, there are discerning customers who have blacklists. One company
that made it on there now is CST. Their Conquistare road tires won't
even last 1200mi in this area. The one I currently have on the rear also
developed tiny cracks that you see in 15 year old car tires with 60000mi
on them. Except this tire is almost new and under 1000mi. So when I have
used up all CST tires here I will never buy that brand again.


Are those CST tires China Made? I've never seen them sold here (not
that they aren't) the "cheap tires" here all seem to be local made and
aren't particularly prone to cracking.


They are made in China. I am quite fond of Thai tires, they are among
the best value for MTB. I haven't seen a 25mm road tire from Vee Rubber
here yet.

1% is a bit much. I try not to go past 0.8% because then cassette damage
will start.

Wippermann chains are good but at least in the 7-8 speed domain I found
that Sachs-Sedis chains beat them by a lot. Unfortunately those have
become unobtanium. Also, from what I have seen a Wippermann 10-speed
stainless chain is over $50 even while on sale. I can get two KMC chains
for that.

One gripe I have with such tests is that they do not properly emulate
the high pulsating peak load a chain is exposed to, including phases
where a clyde is standing in the pedals riding up a steep hill.

Regarding grit it's not so much sand that a chain is exposed to while
offroad. Rather it is wet mud flinging onto the chain and everything
else, often almost for the whole ride.


I think that is exactly the point. The "wear test" chains all appear
to be clean, aligned chains running under what appears to be an
optimum tension, which is hardly the conditions that an actual
bicycle chain is subjected to. While they might be considered as
indicative, but certainly when adding purchase cost into the equation
may well not point to the "best buy for a buck". Which is, it appears,
the aim of the usual cyclist.


That, and then there is the fact that derailer shifts aren't always
super smooth on surprise uphill sections. In tests they usually never
shift. The real test is on the roads or in my case mostly on singletrack.

I did, and didn't see this one. Shazam! There is the next one to test.
The price is in my usual range and it's steel bead which I prefer. Thanks.

According to a bloke who claimed to know the cheaper Thai tires
contain a lot of carbon black which makes the tread rubber harder and
results in the tires lasting longer, which or course is of far more
interest to poor buyers then to the wealthier purchasers.

Perhaps this added carbon black also prevents cracking?

Wealthier purchasers are usually the smarter ones. They do not buy
overpriced gear that has paltry lifetime. Warren Buffett didn't become
rich by buying numerous $100k+ sports cars.

Then that's a good thing, isn't it?

I did read that Jay Leno has some 286 vehicles (169 automobiles and
