Are KMC-Z chains directional?

Directional wear and asymmetric (directional) design are two

That gives me a much better idea of what we're talking about. I had gone out and looked at my top end chains and they had tooth engagement bevels only on one side but otherwise looked identical.

High-Tech!

It wouldn't likely matter for my stuff and I don't care about saving a
few milliseconds per shift. I sometimes even grind off part of the wider
spline and flip around a worn cog in the cassette to milk a few thousand
more miles out of it.

MY GOD Joerg, you're no bicycle aficionado at all!

Yeah, to me bicycles are simply utility device. The hose clamp still
rides along, to keep the steerer from loosening too much.

In Europe my Gazelle frame is often considered a classic and has fetched
prices north of $500 on EBay but ... mine is quite worn and when I had
my last rear tire blow-out I did the unthinkable. Fixed it with gauze
from my first aid kit.

http://www.analogconsultants.com/ng/bike/Gauze.JPG

Those 15mi with the gauze rubbed the chainstays bare on the insides but
it got me home. I took a can of gray Rustoleum that I had left over and
sprayed some of it onto the blue frame.

After the aluminum handlebar broke off (nasty crash) I affixed a MTB
straight bar from steel. My road bike also has MTB pedals which many
purists consider disgusting.

I've got two bikes. The almost 40 year old road bike with its 25mm tires
is for fast rides on pavement, gravel roads and the occasional dirt
road. The MTB has 2.2" knobby tires, full suspension and is for the more
gnarly rides. Even when I expect only a few miles of rough trail and
don't want to walk that section I use the MTB.

Not sure if that group set came with hoods but they might have failed
from too much UV exposure and then they cut them off. Mine from the
Shimano 600EX set lasted almost four decades but I've since removed
them. They do have visible cracks at the edges.


It looks like a long horn beetle. Live and learn, though -- I'd never heard of Shimano Golden Arrow, and its not as though I wasn't paying attention, but I guess in the '83-'86 time frame, I was buying Campy or Dura Ace.


Many bikes including mine were semi-custom built. I bought the frame to
fit my size and then selected all the parts myself. The bike shop
assembled and tuned everything. The customary hgher-end Shimano
equipment back then (unless you really wanted to skimp) was 600EX which
mine has. Some I removed because I installed a longer cage MicroShift
derailer to be able to use MTB cassettes. The brake handles are now
Shimano Altus because I went to a steel flat bar. Don't trust aluminum
anymore after a spectacular failure and subsequent crash at speed.
