Sram:
When SRAM launched our road technology from scratch they reapplied their MTB proven SRAM 1:1 actuation ratio (shifter cable travel : derailleur movement) for 10 speed rear shifting. Easy Actuation helps to simplify/stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up and it stays that way.
ZeroLoss simply means, well, zero lossââ¬Å¡ ÃÂwhen you push on the lever, for an upshift or down shift, the cable is engaged instantlyââ¬Å¡ ÃÂzero loss of movement. There is no middle-ground where youre waiting for the shift to come. Gear changes are instant and precise.
