• Top stock pic is a nipple, recessed one is threaded normally, but I guess there could be some weird recessed nipple I've not seen before.

  • You can use a hose with syringe attached (IIRC) but be careful as mine fell off and pissed fluid everywhere.

    It's a weird design choice and was my first experience of setting up/bleeding hydro brakes.

    Helped my mate build his SRAM Rival disc bike more recently and that's got sensible screw on hoses and syringes which are a lot neater and less prone to popping off for no reason.

    It should be noted that I'm a rank amateur, so maybe proper mechanics don't have the same idiot problems that I do.
