Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like : "Unbound Gravel". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

The race for comfort is rear biased but it should be now about front of the bike...

Experiment. It might be a surprise how low you can really go.

It helps tremendously, especially with rough mountain descents. .
Be careful. I recently went too low with the psi, and nine miles into a gravel race my rear tire was going flat. I put in a tube (while everyone rode past me). Next day, I checked it out, and the tire was not punctured. My guess is that the psi was so low that it burped out most of the air.

Lesson learned.

Yes. Going too low can be dangerous but it is also very tempting. I have tested benefits of going from 40 psi to 20 psi and they are huge.

Yes, as with all things, being careful is good advice.

A gravel race probably isn't the best place to experiment.

The thing I would be most careful about however, is the gravel.cc article linked above. Dropping tire pressure by 50% from 40 PSI to 20 PSI is might be good for comfort but reckless from a safety perspective.

Yes this was done by me to See how far can I go in terms of comfort but you are right 20 psi is a bit extreme so in in future I will conduct additional tests but this time comparing 60 psi to 30 psi.

wasn't popular because it was suspension, or that it was a costly rebuild and too often?

or it wasn't popular because it was limited to 650x38? (smaller sized frames)

there are many reasons other then a specific 'suspension reason as to why something isn't popular.

the slate has some quirky geometry also...

was the Oliver Lefty a more popular version of the Slate than the Rigid Slate though?

I personally have a Rigid Slate and I love it, but you dont see many people with them. From the Slate group on facebook the Oliver suspension seems to be much more popular than the rigid.

Trek has a front and rear isospeed mechanism. Mine boone is before they created a front. But I can tell a difference in the rear.
