I am not sure if their software will allow reverting back to older version FW. If not, the only option is to wait for Specialized to come up with a newer FW to fix this.Mine was the same. Hard to read the number. Does not make sense. I am going to pick up mine from LBS today. I will check with them to see if there is a way to change.

Wish they will just let us do this ourselves. It is such a hassle to have to take the bike to LBS for every little thing. Can't believe they don't even let us adjust the wheel diameter without taking to dealer.
