SRAM has simply introduced a reasonably large replace for the Eagle AXS Transmission customers. The brand new Cassette Mapping firmware replace guarantees improved shift velocity – however solely on sure shifts. Particularly, the firmware replace will increase multi-gear shifts by “decreasing the time between successive derailleur shifts of three or extra.”
Eagle Transmission Cassette Mapping is the mixture of X-Sync expertise on the cassette itself plus, the exact motion of the derailleur itself, that are managed by AXS firmware.
These derailleur shift sequences characteristic particular timings that maintain the chain absolutely engaged whereas transferring throughout the cassette. This permits the rider to shift when and the place they need.
SRAM says that this replace is “primarily based on years of extra post-launch testing and maintains the chain engagement requirements which might be required for the most effective shift beneath load.”
What Does the Firmware Do?
Firmware 2.53.8 principally installs a timing replace to the Cassette Mapping Multishift intervals. What this implies is, on successive shifts of three or extra, the derailleur will transfer faster than it did earlier than between the gear positions. This might be a nice replace to all the Eagle AXS Transmission line.
*This replace makes it sound like your Eagle Transmission will shift sooner, however will it?
Shifting your drivetrain efficiently between cogs takes two unbiased actions. First, the cassette itself should rotate, and second, the derailleur has to maneuver the chain between the gears. The derailleur should transfer first earlier than the chain is launched onto the ramps or “shift lanes” of the cassette to vary between gears.
So whereas the firmware replace will velocity up successive shifts of three or extra gears, the precise velocity of the shift is set by the rotation of the cassette. It appears like SRAM is claiming that whereas the derailleur will transfer sooner from gear to gear, the velocity of the shift itself might be sooner, so long as the cassette is spinning quick sufficient. Formally, SRAM states that “Firmware 2.53.8 is designed to align higher with frequent cassette rotational speeds whilst you experience.”
