They work necely. I have one. It can REALLY make you work though. The killer headwind just needs to go over the bolt that sticks out of your drum, so rather than mounting it to the ouside of your frime, you can probalby put it on the INSIDE, next to the drum itself if you feel you need a straighter line of pull. Don't worry about it though. It is well made and you will be fine with it.
