We know you're anxious to begin navigating, but we have a favor to ask.235 whilst the equivalent X0 mech will cost about ?160 Much like the NX Eagle group, the SX Eagle groupset doesn't quite get the huge 500 range of the top tier groups as it uses a conventional Shimano HG freehub body rather than the dedicated XD driver. That means being limited to an 11T smallest sprocket on the cassette rather than the 10T item, though still giving a very wide range of 454 thanks to the dinner plate-sized 50T sprocket. The cage is made of stamped steel pieces with the mech knuckles being made of injection moulded plastic, held together with rivets, presumably without any special bearing or bearing material and the plastic jockey wheels run on plain (rather than ball) bearings. There are lots more details and weights for all the parts here. The drivetrain gets an alloy or steel chainring and for the 11spd an 11-42t cassette. The 12spd Eagle gets a direct mount chainring a cassette boasting an 11-50t range of which 8 cogs are steel and 4 are alloy. The mechs for both drivetrains are a mix of aluminium and steel making them heavier than more expensive drivetrains such as GX. The 11spd cassette either comes as a one-piece stamped steel or steel with one alloy cog whilst the 12-speed gets a one-piece steel option held together with stainless steel pins. The 12spd rear mechs have alloy bodies with steel cages whilst the 11spd mech is all aluminium. The drivetrains benefit from trickle-down tech from the higher end SRAM groupsets. The new 2021 Eagle Expansion line includes GX, X01 and XX1 builds featuring redesigned derailleurs, cranks, and shifters with backward compatibility. There are lots more details in our news piece here but in short, there is a new cassette with a 10-52t range (520) available in GX, X01 and XX1 specs. There is also a new mech too, SRAM has updated cage architecture to improve chain management. While the new mech is optimized for the 10-52t cogs, it's also backward compatible should you decide to run the regular 10-50t cassette.
