PRO SX4-W computer review
The super-light PRO has a quality feel and works better than we feared at first. It’s a bit of a faff working out which button is which, as there’s no labelling in the instructions. The super-light sticky-backed zip-tie mount fits bars or stems and will squash on to a flat base bar or top tube without worry. The sensor looks tidy, and there are black or white head options.
Despite the small screen, you still get a nice big current speed number, then you can toggle through the secondary speed, distance and time functions. These are pretty small though, and there’s no backlight for nocturnal sessions. We thought the tiny buttons might be an issue with big gloves, but they’ve got a very positive click, and left and right buttons serve the same purpose, for ambidextrous operation.
