XT M780 IS now Shimano's oldest serving MTB gearset but it's still delivering shifting in a light, smooth and ultra durable format.
The rear mech comes in
the regular Shadow version seen here or in Shadow Plus format with a
chain-taming clutch for an extra tenner. Either way, the 3D formed SGS
parallelograms give excellent stiffness and durability. The cartridge bearing
jockey wheels last for ages too and the alloy cages can often be bent back
after being mangled (unlike composite ones) yet the mech is still almost 50g
lighter than the SLX equivalent.
The slick shifting
10-speed cassette carries most of the cogs on a lightweight alloy spider,
saving 32g for only 12$, and the HG95 chain is a longevity benchmark. Shifting
is sharper and faster than with SLX, with an extra gear (four, rather than
three) per downshift too. Shifting can feel slightly indistinct compared to
SRAM on rough trails but XT tolerates age and cable contamination much better.
The front trigger is
dual directional, the shift indicator windows are removable and more kit is
appearing that's compatible with Shimano's I-Spec combined clamps too. Shifters
are available separately if you're planning on going 1x10.
