Handlebar Monitor
TC-MB-28B+E240- 54 × 54 × 26 mm, 58 g
- USB Type-C charging, DC 5V
- Light sensor, alert light and two buttons on the face
- Supplied with the handlebar mount
A handlebar-mounted monitor and two valve sensors that watch pressure and temperature on both tyres and warn you the moment one drops out of range, because on two wheels a soft tyre is never just an inconvenience.
The sensors arrive pre-paired to front and rear, activate on the tyre's own air pressure and set their own alert thresholds. Built to GB 26149-2017.
Clamp it to the bar, screw the sensors on, and it does the rest itself.
The bracket clips into the back of the display and clamps to the bar, then angles to suit your riding position.
Sensors come decalled 1 for the front and 2 for the rear. Tighten one on and the tyre's own pressure activates and pairs it.
Whatever a tyre reads at pairing becomes its standard. It warns at 25% above, 15% below and 70°C.
A clock on the face, an alert LED and an audible warning. Press any button to silence it. The tyre keeps flashing until it's fixed.
Monitor and two sensors, plus the handlebar mount, a sensor battery replacement tool, a hex wrench, two anti-theft nuts and two spare O-rings.


Inflate both tyres to their correct pressure first. Whatever a tyre reads at pairing becomes the standard its alerts are measured against.
When a sensor raises an alarm the tyre's reading and its LED flash together with an audible warning. Any button silences the buzzer; the flashing stays until the tyre is sorted.
