XS-1297 Eagle Transmission Cassette
520% Gear Range. Improved Progression.
The XS-1297 Eagle Transmission Cassette is a major reason why Eagle Transmission offers the best-ever inboard and outboard shifting performance under load. Thanks to its full X-SYNC design, the harder you pedal, the better it shifts. Engineered as integrated and interdependent transmission components, the cassette and derailleur contact directly, ensuring perfect alignment on every bike. The 52T cog steps down with improved gear progression with 44 and 38 tooth cogs in the low end — lasting far longer and delivering more precision with less extreme chain angles throughout the entire range.
