Re: hi everone
Welcome to the forum. If I may suggest, do some reading by using the Google Custom Search feature. Just type in a word/s 'friction drive' and you'll be rewarded with plenty to read on the subject from those who have installed it. Same for any question that you might have. If you can't find what you're looking for come back and ask. We're always here to help.
As far as a comparison between the two types of drives you'll get responses from both sides. Those who run chain drive swear by it and the friction drive folks are loyal to that method. You'll need to research and make a decision for yourself. There are many variables that you'll need to consider. Good luck.
