Ideal for home mechanics and workshop users servicing Shimano hydraulic drop-bar bikes with compatible M7-thread road or GRX brake levers.
The Shimano TL-BR002 Funnel Unit for ST is the dedicated bleed funnel for Shimano hydraulic road and GRX-style levers that use an M7×0.75 bleed port. Instead of relying on an adapter, this funnel threads straight into compatible levers, which makes setup simpler and gives you a more secure connection while you're burping the system or doing a full bleed.
For home mechanics, the big win is control. Shimano’s design uses an increased-volume funnel and an oil stopper to help reduce mess, and the larger cup design has been noted for giving you a bit more working room when flushing old fluid or coaxing air out of the lever. If you service drop-bar Shimano brakes regularly, it’s a neater and more straightforward option than mixing generic syringes, cups and adapters.
This is the one to choose if your bike runs Shimano hydraulic STI / dual control / GRX road-type levers rather than Shimano MTB levers. It’s a small workshop tool, but it’s the sort of small tool that saves time, avoids frustration and makes it easier to get back to a firm, consistent brake feel.
Direct M7 road-lever fit
Threads straight into compatible Shimano ST and BL road-style hydraulic levers with M7×0.75 threading, so you don’t need to rely on a separate adapter.
Made for hydraulic brake bleeding
Built specifically for Shimano hydraulic disc brake bleeding, whether you’re doing a quick lever bleed or part of a more complete service.
Larger funnel volume
The increased-capacity cup gives you more room when moving oil through the system and helps reduce the need to constantly top up the funnel.
Cleaner workshop job
The funnel and oil stopper are designed to help limit spills, which is especially useful when working around bar tape, hoods and painted frames.
Better suited to road lever angles
A dedicated road-lever funnel makes more sense on drop-bar bikes because it matches the M7 lever interface used on many Shimano road and GRX hydraulic controls.
Useful for repeat servicing
If you maintain more than one Shimano drop-bar bike, having the correct dedicated funnel makes routine bleeds faster and more consistent.
General
Features
Great for
Maybe not for
Compatibility is the key point here: this funnel suits compatible Shimano hydraulic road-style ST/BL levers with an M7×0.75 bleed port. It is not the same funnel used for Shimano MTB levers, which commonly use the TL-BR003 M5 style. Common compatible lever families listed by retailers and Shimano service documents include road and gravel models such as Dura-Ace, Ultegra, 105, Tiagra and GRX hydraulic levers.
vs Shimano TL-BR003 Funnel Unit for BL
The closest alternative inside Shimano’s own range. TL-BR003 is the dedicated funnel for many Shimano MTB levers with an M5 thread, while TL-BR002 is the correct direct-fit option for compatible road and GRX lever bleeds.
vs Park Tool BKM-1 Hydraulic Brake Bleed Kit — Mineral
A more complete workshop kit that includes syringes, hoses, blocks and a Shimano drop-bar extension. It’s broader in scope, but far more expensive if all you need is the road-lever funnel itself.
vs Jagwire Pro Bleed Kit
A universal-style mineral oil bleed kit aimed at mechanics who work across multiple brands. It’s flexible, but fit and adapter coverage can vary by version.
Check the lever thread before you buy
This funnel is all about the M7×0.75 fit. If your bike has Shimano hydraulic drop-bar levers, this is often the correct choice, but Shimano MTB levers commonly use a different M5 funnel.
Best paired with the rest of a proper bleed setup
For a full bleed, you’ll still want the rest of the gear: the correct mineral oil, hose, syringe and the usual workshop basics. This funnel is the lever-end tool, not a complete kit on its own.
A dedicated road funnel is easier than using adapters
If you regularly bleed Shimano road or GRX brakes, a direct-fit road funnel is simply less fiddly than swapping adapters onto an MTB-style cup.
Especially handy on GRX and modern road bikes
Road and gravel hydraulic levers can trap air around the lever body, so having a secure funnel at the lever end makes routine burping and bleed work easier to manage.
Shimano is a Japanese component brand founded in 1921 in Sakai, Osaka. The company began with bicycle component manufacturing and has grown into a global business focused on bicycle components, fishing tackle and rowing equipment, while keeping its headquarters in Sakai.
In cycling, Shimano is best known for building complete component ecosystems that span road, mountain, gravel, commuting and e-bike use.
