Jagwire Shimano brake pads are constructed with HeatShield technology which works by creating a heat shield between the compound and the metal disc brake itself, ensuring better friction. This means that the pads can perform at higher temperatures for longer, providing that extra resistance even in wet and slippery conditions. Brakes are important at the best of times, but when you\'re careering down a mountainside at a 35° angle heading towards a particularly volatile section of scree, you\'ll likely appreciate the peace of mind from having invested in some serious stopping power.
