I'm experiencing intermittent latency in shifting the gear hub portion of my SRAM dual drive, often 2-3 seconds before the change kicks in. It's more common when going to the mid level 1:1 than to high or low. Are there some mesh locations that need be met to synchro into the selected gear or is this suggestive of a linkage problem. Alternatively, could this be an early gear hub failure symptom? Sometimes associated with the downshift latency (but not always) is a resistance at the shifter to downshifting gears, haven't noticed the shifter resistance going up, just the latency.
