While the aim of S-1000 is to reduce the cost of Transmission-family components,\u00a0this newest mountain bike groupset<\/a> will, for the time being at least, only be available as original equipment (OE).<\/p> That means it\u2019ll be fitted to some complete bikes, but you won\u2019t be able to pop down to your local shop and buy any specific S-1000 components or a full groupset to fit to your current bike.<\/p> This is also the first time that SRAM is offering roughly the equivalent to NX-level<\/a> components with wireless AXS technology, previously reserved for the GX tier<\/a> or higher. SRAM’s drivetrain tiers cover (from most expensive to least expensive) XX1, XX01, GX, NX and SX, and Transmission tiers now cover XX SL, XX, X0 and S-1000.<\/p> Trickledown technology of this nature is great for the consumer. Hopefully, it means we\u2019ll see brands speccing electronic shifting<\/a> on more affordable bikes.<\/p> For those who have seen GX Transmission<\/a>, the S-1000 derailleur\u2019s looks will be familiar, thanks largely to the horizontally-mounted battery.<\/p> It also shares the same direct-mount design \u2013 that eschews the derailleur hanger in favour of mounting it directly to the frame\u2019s dropout \u2013\u00a0and adjustment-free installation<\/a>, just like all other Transmission components.<\/p> Also identical is the software-based \u2018cassette mapping\u2019, where the derailleur waits for a cassette ramp before shifting gear.<\/p> Differentiating it from GX is the S-1000 derailleur’s \u201cunique black anodized finish\u201d and a clutch system that now uses a \u201cdrag spring damper.\u201d<\/p> However, the S-1000 derailleur can still be fitted with a clutch or cage from any other Transmission level, whether that\u2019s XX SL, XX, X0 or GX, according to SRAM.<\/p> The higher-spec derailleurs’ rebuildable parts are also carried over.<\/p> Both the outer skid plates and two-piece outer link can be swapped using common tools, and like the other derailleurs, the cage is removed by rotating it.<\/p> The derailleur is compatible with all of SRAM\u2019s AXS controllers and the AXS smartphone app.<\/p> Built from forged aluminium, the S-1000 cranks are claimed to be robust and reliable.<\/p> They\u2019re available in 155mm through to 175mm lengths, in 5mm increments, and work with any Transmission eight-bolt chainring.<\/p> That means they\u2019re compatible with the same composite bash guards found on GX and X0-level rings. Bash guards can be retrospectively fitted to the S-1000 crankset, but standard fitment is determined by the bike manufacturer.<\/p> An eMTB-specific crankset is also available, and is compatible with SRAM, Brose, Bosch and ISIS bottom bracket ebike motors<\/a>.<\/p> The new S-1000 Eagle Transmission cassette has the same 10-52t range as all of SRAM\u2019s XD Driver<\/a> Eagle cassettes.<\/p> The same X-Sync design as the rest of SRAM\u2019s Transmission cassettes<\/a> is also said to deliver improved shifting performance under load.<\/p> Again, it’s compatible with all other Transmission components, including derailleurs and chains.<\/p>SRAM S-1000 Eagle Transmission Derailleur<\/h2>
