https://off.road.cc/content/news/are-four-piston-brakes-finally-coming-to-gravel-14577

SRAM has a patent for 4 pot hydraulic’s which are getting more common on
MTB’s now. I’m really unconvinced it’s needed the Tiagra and SLX two pots
on my MTB and Gravel bike with Finned pads hold on well with regard to heat
fad and power in general.

Undoubtedly they would be more powerful but I’m not sure I can see the
benefits, and I’m a heavy MTBer at heart so I do push the gravel bikes
brakes fairly hard and I’ve been impressed with two pots.

I'm pretty happy with the cable BB7s on my hardtail, so I think I'd
agree the incremental benefits aren't worth the exponential cost to the
average rider - much less so on a gravel bike.

Wait! I thought a fundamental principle of bike marketing was that
anything "better" is mandatory! ;-)

That's true for marketing.

I found the cable disks to be better on flat bar bikes, admittedly quite a
few years ago vs Gravel bikes where I found they where sub par both in
power and with muck getting into the mechanism and trashing the callipers.

While I have found the jump to hydraulics a significant improvement, I’m
unconvinced by the argument for 4 pots, which admittedly is only a patent
ie like electric brakes and shimano may well never happen!

Realistically even at 95kg or thereabouts my MTB copes well with two pots,
which I brake much harder on the MTB than the gravel bike.

But you’d run into the limits of the bike’s geometry/suspension/tires etc
long before brakes, at least with the gravel bike.

My thoughts exactly. I'm not sure a gravel bike is capable of the
extremes necessary to get the most out of that level of braking.
