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 a 20 ml TPX caliper syringe and a long-lasting tube; TPX is the spec call-out the Basic kit's plain 20 ml syringe doesn't carry. 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 the full flat-bar Shimano hydraulic family: 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 Bleedkit.com does not sell that adapter on its own — the M5-M7 adapter ships inside its newer Workshop Pro Mineral kit. 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 sponsors professional road and mountain-bike race 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. That repeated caliper-end duty is what the 20 ml TPX syringe and its long-lasting tube are in the kit for.

FAQ

Does one kit really cover both flat-bar and drop-bar Shimano levers? Yes — that is the Workshop Edition's job. It carries two bleed blocks, one for flat-bar Shimano (2- or 4-piston calipers) and one for drop-bar, plus a brass adapter that puts the 30 ml M5 funnel onto the drop-bar Dura-Ace, Ultegra, 105, GRX, and Tiagra levers. The one boundary: the 2026 R9300 / R8270 generation moved to an M7 lever thread this kit doesn't include.

Do the bleed blocks fit 4-piston brakes like Saint or XT? Yes. The flat-bar bleed block is the 2-or-4-piston type, so it seats 4-piston Saint, Zee, and XT calipers as well as the 2-piston brakes across the Deore, Alivio, Acera, Alfine, and Metrea range; a second, separate block covers Shimano's drop-bar hydraulic brakes.

What is the stainless steel tube insert for? It's the small stainless sleeve that provides a guided fitment between the caliper syringe's tube and the bleed nipple, so the connection stays located during the bleed instead of working loose. It ships alongside the 7 mm wrench and the gravity-bleed clamp at the kit's caliper end.

Are spare O-rings included? Yes — four spare O-rings ship in the box, and the base that holds the funnel and adapters carries spare O-ring studs on its underside, so replacement seals stay with the kit rather than in a drawer. The threaded stainless plug with hanger closes the funnel between fills.
