    I personally weighed a set of XTR/XT hydro brakes and here's the break-down....

    - Front and rear XT levers (BL-M756) = 248g
    - XT 160mm rotor with bolts = 140g
    - Front XTR caliper with bolts and pads = 103g
    - Rear XTR caliper with bolts and pads = 105g
    - Front line (900mm) with bolts, olive, uncut, no fluid = 32g
    - Rear line (1700mm) with bolts, olive, uncut, no fluid = 45g

    Now, with the lines cut and the system fully bled, the weights are:

    - Front lever, line, fluid, caliper, bolts = 263g
    - Front rotor with bolts = 140g
    Total = 403g

    - Rear lever, line, fluid, caliper, bolts = 279g
    - Rear rotor with bolts = 140g
    Total = 419g

    Total = 822g

    As a comparison:
    1 - my B4 SLs are 614g/set cut-n-bled (160mm/140mm) or 631g/set uncut.
    2 - my B4 SL+ are 697g/set uncut (160mm/140mm).
    3 - my Hope Mono Minis are 770g/set uncut (160mm/140mm).

    All weights were personally done by me on a digital scale.
    Ride Hard,
