At only 75mm long, this small kit might seem insignificant - but it's packing enough brake fluid to fill two levers. And at only 20g when it's dry (<30g full), you'll hardly remember it's there.

DOT or mineral fluid? No problem - the kit works with both, so you don't have to switch between them. The M5 connector fits most Shimano & SRAM brake levers, and the seals are even tested to an altitude of 12,000m  - so you won't find brake fluid through your bag.
