Check and compare the price between these caps and the other brand names. These do the same thing, take seconds to put on, are WAY cheaper, and honestly, none of these caps are noticed after you've put them on. HIGHLY recommend these to cover the shaft if (like me) you've removed your heel shifter.
Didn't use the heel shifter mainly because it set too high and to move it to the next lower groove would not let the shifter travel enough to perform the shift so I just took it off. Then I needed something to cover the end of the shifter shaft and this works and looks great. I also have a lot more room to move my left foot around now.
