Overview
SRAM Eagle 70 Transmission is the affordable mechanical 12-speed T-Type groupset, with a replaceable 5-cog cassette cluster aimed at E-MTB riders.
Eagle Transmission is SRAM's T-Type 12-speed 1x system: Full Mount derailleurs bolt directly around the rear axle with no hanger, and cassette mapping plus X-Sync tooth profiles give, per SRAM, the best shift under load – even with the added power of E-MTB. All T-Type components can be mixed and matched.
Eagle 70 Transmission is 'Transmission unplugged': mechanical, durable and affordable, with no derailleur hanger and no adjustment screws. Its XS-1270 cassette has a replaceable cluster of five gears so E-MTB riders can replace the hardest-working cogs, and the chainring is tool-grade steel.
