Greatest cycling invention of the last 25 years?

[Fastpedaller]

Whilst I have never had them on a pedal bike, they are far superior for motor vehicles so I can't see why they'd not have the same benefit on a bike

Maybe something to do with the differing pressures and loads involved, comparing bikes with cars.

When I rode tubes I would be at 100+ psi. On tubeless for road riding I'm 60 rear, 55 front and on gravel 55 rear, 50 front. I could probably go lower still but I still have a hangover regarding pressures from my tubed days.

Could the lower pressure for road riding result in more chance of rim damage from our lovely roads?

Also - does the lower pressure increase rolling resistance??

Indeed. You are likely to be running at close to twice the presure a car tyre will run at, and with far thinner rubber as well.

Could the lower pressure for road riding result in more chance of rim damage from our lovely roads?

Possibly slightly so, but not really much more, even if the tyre gets very compressed, it will still provide a little buffer.

Also - does the lower pressure increase rolling resistance??

So long as you don't go silly low, it actually tends to improve it.

I don't think so and speaking for myself it's very rare for me to hit a pothole at any speed let alone fast enough to do damage. I would be disappointed if I couldn't avoid 99.9% of potholes deep enough to cause damage.

I ride 32mm tubeless. To accommodate this on my new road bike I've chosen DT Swiss carbon gravel wheels. Pretty much bullet proof.

Also - does the lower pressure increase rolling resistance??

I would say not and if there is at my level it wouldn't make any noticeable difference. What does make a difference to rolling resistance is tyre quality. It's well worth paying for the very best one can afford.

But wheels need to be heavier....

How so???

 

[Punkawallah]

How so???

I’m going to guess ‘more sturdy, and less susceptible to pot-hole damage’.

 

[Andy in Germany]

How so?

The hub is larger and carries the Disc itself, and the wheels need to be more solid because of the forces involved when braking near the hub as opposed to braking on the rim. I doubt most people will notice the difference overall.

 

[Jameshow]

How so???

Because they are cross spoked with more spikes as the spikes take the braking load where as a rim brake can be 16 spokes radially!

And about as robust as fondue cheese

Yes if your 109kg+ if your 70kg no worries

Not had any problems with mine despite lejog etc.
