Description
Not every tube on the shelf is rated for real trail abuse – the Bridgestone MXH Tube – 80/100-21 is Bridgestone’s answer for setups that need to survive rocks, roots, and whoops. Bridgestone positions the MXH a notch below the MXUH in its motocross tube lineup, trading a bit of weight savings for extra wall thickness that holds up to washboard trails, hard cornering loads, and the kind of casual abuse a 80/100-21 setup sees on a weekly ride.
- Sized for 80/100-21 spoked-wheel fitment
- Heavy-duty rubber construction built for off-road, trail, and dual-sport use
- Valve stem type (TR-4) matched to common spoked rim setups
- Even wall thickness for balanced inflation and reduced flat-spotting over time
- A dependable step-up replacement over stock or economy-grade tubes
- Manufactured under Bridgestone’s motorcycle tube quality standards
Bridgestone tubes are manufactured to a consistent wall thickness and a specified valve stem type, which matters more than most riders realize once a tube has a few seasons of heat cycling and constant flex behind it. A tube that runs thin in spots or drifts off the printed size will wrinkle inside the tire casing, chafe against the rim, and eventually let go at the worst possible time on the trail or track. This tube is meant to disappear into the wheel and just work, which is the whole point of buying a spare from a brand with Bridgestone’s track record.
