Bleed Kits

A clean bleed makes the difference between a brake that bites at the right point in the lever throw and one that feels spongy after a long descent. The bleed kits collection covers the hydraulic systems shoppers actually run on road and mountain bikes today: Shimano mineral oil, SRAM DOT, and Magura Royal Blood. Each system has its own funnel thread and block thickness, and a kit built for one fluid rarely fits another. Most kits in this collection come from BleedKit.com, a Ljubljana-based partner brand building system-specific bleed kits since 2011. The 2026 lineup accounts for the new Shimano R9300 and R8270 M7 funnel thread plus the 5.0 mm bleed block on SRAM Maven Bronze, so a kit bought today fits the brake on the bike today.
