The amazing PCB 'Pancake Brake' is now reality. The PCB is the worlds first pistonless hydraulic brake system. By simplifying the caliper and effectively removing the pistons, the PCB becomes light, efficient, economics, low profile and virtually maintenance free.
Strong Viton rubber diaphragm seals push the pad as there are no pistons to stick. The pad retraction is guarateed every time.

The Airotor is already on the market (although coloured versions are new for 2009). It's claimed to be the lightest stainless steel rotor available - a 203mm one comes in at 136g and a 140mm one just 68g. It's not hard to see how that weight has been achieved - the Airotors are mainly hole. Ashima makes big claims for performance, wear and heat dissipation, although for some riders we suspect that ultra-low weight and funky looks may be enough on their own...
And for fans of the old school, Ashima's even launching some very early-90s looking forged/CNCed V brakes and levers. The company already makes about a bazillion different kinds of brake pads for rim brakes, so it's a natural development.
Also new from Ashima is a simple answer to the oft-asked "sintered or organic pads?" question - both at once. Reasoning that each type of compound has advantages and disadvantages, and that every advantage comes complete with some other disadvantage, Ashima's SOS pads use sintered pad material at the ends and organic in the middle.
The claims for the SOS are certainly bold - cold performance of an organic pad, high temperature performance and wear characteristics of a sintered one but with three times less heat being passed to the brake piston. According to Ashima the SOS is a truly universal pad. It'll be available to fit most of the popular brake systems.
