Tried the S3 idle knob but it wouldn’t screw in enough to work but the Beta one was seamless and easy to turn but enough resistance to not back out over time.
Very impressed and happy with the purchase!
I'd be sore after only 10 miles on the stock seat. The Seat Concepts comfort seat made a huge difference. Recently did 140 miles of mixed terrain and felt pretty darn good afterward. No more monkey butt.
