I generally don't care when Podcast goes into options and not facts.
But the DI2 talk at the end of this podcast was not correct.
I have been on DI2 doe 3 years and do all the work myself.
#1 the PCE-1 shimano tool lets me update my shimano with new firmware. FREE
#2 If your bike is working It will continue to work indefinitely WITHOUT ANY UPDATES!
#3 Before i had the PCE-1 tool i went into a shop and had my buttons programed
the way i want and they flashed a few new firmware and didn't change me anything.
Not $250 dollars. electronic is the future. dont be scared.
saying that I still have 3 acoustic bikes.
rally on!
