Bleedkit.com Workshop Shimano Bleed Kit

A multi-bike Shimano shop bleeds enough levers in a season that the syringe handling itself becomes the cadence-limiting step. The Workshop Shimano kit answers that with TPX-bodied syringes in place of the harder polypropylene the basic kits use; the TPX gives a smoother plunger draw, slightly better fluid-feel at the lever-side pull, and a longer service life on the syringe body itself. The kit also carries everything for both flat-bar and drop-bar Shimano hydraulic levers, which is the second part of the workshop equation: one box covers every Shimano hydraulic on the workshop ticket-rack from XTR down through Tiagra.

What's in the kit

A 30 ml transparent funnel with a brass M5 thread sits at the lever end, threaded for the standard pre-2026 Shimano master cylinder. A stainless threaded plug with hanger closes the funnel between fills. The caliper end ships with a 20 ml TPX syringe and a long-lasting tube, plus a stainless tube insert that guides the tube cleanly into the bleed nipple. Two bleed blocks live in the kit, one for flat-bar Shimano (covering both 2-piston and 4-piston calipers) and one for drop-bar; a brass adapter brings the M5 funnel onto the drop-bar Dura-Ace / Ultegra / 105 / GRX / Tiagra family.

Compatibility

The kit fits every flat-bar Shimano hydraulic brake currently in production: XTR, XT, Saint, Zee, SLX, Deore, Alivio, Acera, Alfine, Metrea. With the brass adapter and drop-bar block, it also fits pre-2026 drop-bar Shimano: Dura-Ace, Ultegra, 105, GRX, Tiagra. It does not fit the new 2026 Dura-Ace R9300 or Ultegra R8270, which use M7 instead of M5 at the lever, and that funnel adapter sits outside this kit and is currently a separate-accessory call. Fluid is not included; the kit is designed around Shimano mineral oil.

Bleedkit, in Ljubljana since 2011

Bleedkit.com builds per-brake-system kits in Ljubljana, Slovenia and has done so since 2011; distribution through Euro Toolworks is the same path that brings Unior cycling tools to the North American market. Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. The Workshop Shimano kit is the multi-bike version of the family: every flat-bar and drop-bar Shimano lever the workshop sees goes through the same box, which is the part the cadence math depends on.

Pro tip from our mechanics

For a workshop running back-to-back bleeds, the savings compound at the caliper end. Pull the caliper, mount it in a bench vise with the bleed nipple uppermost, and run the gravity-bleed clamp with the funnel pre-filled. The caliper end of the bleed cycles in under a minute per brake once you're set up; the slow part is funnel transitions between bikes, not the bleed itself. The TPX syringes survive this duty cycle in a way the basic-kit syringes don't.
