Only heel shifter I ever had prior to the SEEG was on my first bike, a 90cc Bridgestone in 1966. It survived approximately one week before I hacksawed that sucker (it was one piece, unlike the Harley version). The SEEG lost the heel shifter the day after it came home and it has never been missed. If you have a transmission that shifts properly, I don't see any need for a heel shifter. Sure, when you have one that shifts like crap it might help to be able to pound it into gear with your heel, but that method makes me cringe every time I see and hear someone doing it. Best thing about getting rid of it is the freedom of movement you gain, and a secondary consideration is not worrying about having the POS jammed through your ankle in an accident. Besides, without the scuff mark on the top of your left boot, how is anyone going to know you're a real biker and not just another poser?
