If you are willing to give up 1mph this easy, fine. I am not and I
have found a much better solution.


Joerg, your arguments are monuments to inconsistency.

You've rhapsodized about stopping to smell the flowers, stopping to pet
the dogs and horses, taking time to find a nail and rock for a
Flinstone-style chain repair instead of using a chain tool... Yet now,
being slowed one mile per hour is somehow critical??


In the valley, yes. As you should have figured out by now riding along
major thoroughfares, even if they have bike lanes, is no fun at all for
me. I want to get that behind me and the faster the better. Vrooom,
vrooom, Diesel stench, yuck. Horses, dogs and so on are not to be met
there. They are met on singletrack here in the hills and on MUP in the
valley. Even on the long MUP along the American River I am sometimes in
a hurry when on an errand run.

To sum it up: _I_ want to be the decision maker on how fast the journey
goes, not some poorly engineered piece of equipment.


So is that the only place you ride?? You give the impression of
oh-so-gnarly
riding. Once again, your song changes wildly depending on your
argument.


If you had followed more carefully you'd have know that there are two
places I ride a lot: Here in the hills and then down in the Sacramento
Valley. As I wrote many times that valley is huge and very flat.
Nearly all errand rides have to head in that direction because that's
where nearly all stores are.


Yes, and you've given photos and videos of hilly off-road trails, and
said that your mountain bike has to be super-rugged to survive them, so
you've reinforced racks, built stout battery boxes, choose heavy tires
etc. because weight doesn't matter to you.


Weight indeed does not matter, sturdiness is all that counts for me. So
I have modified the MTB and to some extent the road bike (some of our
roads wouldn't be considered roads in the east).

On the MTB I do not care much if a ride on singletrack takes 15 minutes
longer. As happened on Wednesday where I spent 15mins with a horse and
then 5mins with another down the trail. Also watched a hawk who did fun
aerobatics which is a rare sight. I looked at the time at a particular
point where I'd normally barrel through at 1320h and it was already
1335h. So what?

When I use the road bike and have to be at a meeting at a particular
time that is obviously different.


Perhaps you'd make more sense if you took notes on what you've already
posted, then reviewed them before the next time you post.

Perhaps.


No, it would make more sense if you paid more attention to detail. Some
of us are not restricted to same old same old when it comes to riding.
Some of us have a road bike _and_ an MTB, and they use both kinds of
routes. The riding is _very_ different and so is the terrain turf. You
might also try to grasp the difference between utility rides and fun rides.


Again, you're a marvel of inconsistency. Weight doesn't matter on the
mountain bike because it has to be oh so rugged for your oh so gnarly
riding, including the off-road expeditions you've described to reach
your customers. But dyno drag equivalent to climbing eighteen feet in
mile is unthinkable?

I was talking about riding 20 mph with the dyno off, 19 mph with it on.
You pretend that's a critical difference for you? Over a 20 mile trip,
it would amount to three minutes difference. No reasonable person would
schedule utility trips so tightly that such tiny margins would be
important. If you did, you're going to be in trouble the next time the
wind shifts unexpectedly.

And wind does shift, Joerg. It shifts as frequently as your arguments.
