yes! Renner has a Harmonizer and we've used it a couple of times on my bike:)
not much activity on the /7 since my last mini-tech day with Mike and Renner. My wife and I finally got into our new house and have been busy getting things ready for furniture. I'm going to a "real" tech day here in SD this weekend, but probably for looking and learning. I don't think I'll get much wrenching time on my bike until April...
