What to do in the event of a total blackout: a Revolution!

I think you should test the tyres for directional performance!

Some phones have an accelerometer, velocity shouldn't be a problem, fixed point on a chosen surface - the Gravel of a running track might be good...

there might be an easier way, but I'm willing to bet there's no measurable difference.

I would have marked that tread pattern the other way round anyway😆

Well, I want to try it soon. I want to see people's faces when I come across their carbon bikes with big wheels and all the same colors.
Although I don't think I'll use the Time Sierras, I'll put on some first-generation ATACs for that ride.
I'll take the opportunity to check the direction of the tires, although at my current speed, I don't think the conclusions will be optimal.
🤣
 
looks great - always thought these were cool back in the day and the colours on yours are fantastic
 
The reason tyres have a direction on them is because when they are made they are joined diagonally so it is safest to run them one way. However it is mostly just to cover themselves as lots of racers used to have them fitted the other way after a while to try and squeeze a few more laps out of them.

That is for motorcycle tyres anyway, I hardly worked with car tyres and never with bicycle tyres except for seeing them being made.

I am finding it very difficult to not buy a Kirk frame even though I have zero space for another bike so it would just remain a frame to look at.

Bicycle tyres direction was about tread pattern grip rather than high speed structural performance like a motor vehicle tyre.

The same tyre is often recommended opposite orientation front or rear, like these.

Looking at the ground contact patch, chevrons pointing forward give greater grip for drive, chevrons pointing backwards give greater grip for brakes.

It's true that the manufacturer makes the tire with a specific use and direction in mind, and that should be respected.
It's also true that, especially in the 90s, we sometimes used the reverse direction because it sometimes suited our driving style or to minimize wear on the rear wheel (there was a time when grip depended on very soft durometers, and the more aggressive the contact, the faster the tire wore out. I remember using Nokian tires, the Boazobeanna X, and the rear tire barely lasted two weeks...a fortune in money per month!)

What I've never understood is why manufacturers were so stingy as to print only one logo on bi-directional tires! That means the two logos never appear together.
:LOL:

I've had the frame hanging from the wall for months without any assembly, and it's beautiful, but...
Once it's built, it's a different story. I've seen many Kirks with different assembly lines, and they're all very beautiful.

Is it true you got banned for this comment?
Or is it a joke?
I just read your comment right now, and I don't see anything offensive.
