I had one of these on my Cross Country Tour. I eventually switched to the Victory brand heel shifter, which took some getting used to because the Victory heel shifter has only a small area to hit with your heel.
1). The KewlMetal shifter is up-and-down adjustable, as has been said.
2). I drilled out the hole in the KewlMetal shifter and put in an Avon peg, which is much bigger. I think I still have that shifter, with the enlarged, more-standard-sized hole, in my shed. If you want it let me know. I will charge you for shipping and add $10 only.
