Saw the BrakeForceOne thing the other day on singletrack and went looking for a price, the cheapest I found it for is about 340 quid.

That was from here.

If they are as good as they're claimed to be may have to invest.

Please tell me that price is for a pair and not just one...

Edit. Ok it is just for one :mellow:

As far as I can tell essentially it's a smaller piston moving the larger piston to the rotor which then engages for more stopping power. That means you can have the power from a large piston but no issues with brakes rubbing all the time like you would if it were a brake with just a large piston, or the other way round if it's in the lever.

Sounds like it would feel a bit mushy and weird.
