Is there a technology difference or an advantage of the new ELSA 10R? I am in the process of ordering one now and prefer the look of the SRAM Red but performance trumps aesthetics...most of the time. Is the SRAM Red basically obselete/discontinued and I should get the ELSA or are they essentially equivalent besides the weight? Thanks!
The technology is the same between the SRAM RED and ELSA powermeters. The SRAM Red version is certainly continuing. It's the SRAM S975 Quarq model with the larger electronics pod that has been discontinued.
The main difference is the SRAM Red Quarq is sold with Yaw compatible chainrings which are what you'd want to use with the newest SRAM Red drivetrain that has the Yaw deraileur. It has one of the chainring bolts hidden behind the crank arm. The crank arms are branded "SRAM".
The ELSA powermeter has the same features as the RED Quarq (power balance, 1.5% accuracy, etc), but it comes with the standard Red Black 10 speed chainrings without a hidden bolt. This allows folks in the field to more easily change their chainrings. The crank arms are branded "Quarq".
In other words, I'd say base your decision on which drive train you are planning to use the powermeter with.
