How many miles does it take to get to wear out the rubber hoods on Ultegra 9 speed?

How long is a piece of string? I mean, how rough are your hands? How
much weight do you put on the hoods? How much riding do you do hanging
on to the hoods? What constitutes worn out?

I'd rather know why a sachs chain now lasts only 1200 miles where it used to go 2000

Made in China now perhaps?

Eating tortilla chips while riding? Jalapeno-laced or not?

The current Sachs-Sedis chain on my road bike is now well past 2000mi
and still good. But it was a stashed away version from 10 years ago.

Does that mean you can't recommend this brand anymore?

I think my last Sora hoods were looking the worse for wear after about
25,000 (maybe a bit more), ie a hole where my hand rubbed the rubber
away. My current ones still look pristine at 10,000km

Think about this - a chain used to drag really hard if you went to extremes - low/high or high/low. Now testing laboratories show that there's no measurable difference when you do this.

This would suggest to me that chain sides are thinner now than in the past so the chain is less rigid. This also would mean that there is either more play in the bearings to begin with or the steel in the rollers is softer than before so that it can flex.

I am sure glad my road bike is 7-speed. When I can find a decently
priced 7-speed MTB cassette with 36T in there I'll probably reduce my
MTB from 10 to 7 gears in back as well. Chain life being a secondary
reason though.
