Specialized Speedzone Sport review

This computer’s bulit like an outhouse, with basic functions and a big, clear display that’s easy to read, all for under £30.

The cable is good and thick, well bonded into the sensor and head unit mount, and the mount itself is simple but functional.

The sensor is very tolerant to the magnet being located quite far away from it, and also puts up with the magnet travelling past the sensor quite fast  if it’s located further out towards the rim.
