SRAM X01 Eagle 12-Speed Trigger Shifter Lunar, B2, Rear

Will improve your shifting quickness when paired with a GX or above derailleur

It is heavier than say the NX but that’s because it completely made out of metal. Shifts are stiffer, crisper? I dunno it just feels sturdier. The downshift lever is adjustable and it seems like it sits lower or more forward than NX or GX. Also, I could swear that you can down shift 5 gears at a time which is better than NX and GX, in those you can only down shift 3 gears at once. Would recommend a very nice upgrade from what ever you have now.
