Don’t forget a new chain breaker for the 219 chain. And I have a set of 35 axle sprockets for you. PM me.
You don’t need another drive sprocket, except maybe for really fast national courses. I’m getting one just for the track and hopefully some of the fast courses at Wilmington and Lincoln. That’s especially true if you run a 35 chain since you can get smaller axle sprockets with the 35 teeth than 219 (it’s a major challenge with the 219 that you can’t get smaller than 64T).
