The single speed hub conversion does not replace your clutch bell or clutch. The single speed hub is for your spur gear. As far as I understand (and correct me if I'm wrong here guys), you can run the stock clutch bell with the single speed hub. I run a E-LST so I can't give you an informed opinion on that. If you want my opinion, bite the bullet and convert that dog to an E-LST. You won't be disappointed with the top or bottum end with a single speed hub if you go BL, I can assure you of that
