Riders interested in switching to disc brakes on the road have little choice but to get a new frameset and wheels. However, they don`t have to get a complete new groupset, too, IIIPRO A8000 cable-actuated disc-brake calipers will get the job done while allowing them to keep their existing gear.
HYBRID TECHNOLOGY
The IIIPRO A8000 is a mechanical/hydraulic hybrid that works with standard levers: a standard brake cable links the lever to a small arm on the caliper body, which then operates a hydraulic master cylinder piston. That piston pushes mineral oil through the body to the slave pistons, which then squeeze the pads against the rotor. As compared to purely mechanical disc brakes (like the TRP Spyre or Avid`s workhorse BB7), the claimed advantages of hybrid calipers include increased power, a more positive-feeling lever, and better resistance to weather and road grime.
One the biggest advancements is size, and the IIIPRO A8000 is admirably compact. Even as compared to the TRP Hy/Rd - arguably the best of the breed - the IIIPRO A8000 is substantially smaller and lighter. Actual weight per caliper is just 132g with pads but without mounting hardware, plus another 83g for the included 140mm-diameter six-bolt rotor - not exactly feathery, but more than 130g lighter per pair than the TRP.
That slimmer design also allows for an open-backed rear window for better airflow over the pads relative the the TRP`s more closed-off shape, plus the Shimano-compatible pads install from the top for easier replacement. A small tool-free adjuster dial adjusts the angle of the arm relative to the piston shaft, too, and users can tweak the lever feel and power depending on the angle chosen.
