Used it the other day, works well. There was a little bit of flex in the head when gripping it by the seat post, but still worked great. When I say flex in the head, I mean you would want to put a hand on the frame if you were going to torque down a bottom bracket, but for regular stuff, it works awesome. It was SO NICE doing a brake install and bleed on Junior's bike without having to work hunched over on the ground.
I tried going for a ride the other night, and the chain was dropping almost instantly under any kind of torque. I had to put it on the large chainring and listen to some nasty noises and try to make it through 3 miles of tech trail in highway gear mode. Needless to say, my legs were fried. Took it to Trek, he cleaned out and regreased bottom bracket and said the front derailleur had rotated some. It didn't look to me like it was off when I just eyeballed it on the trail, but it seemed OK out in front of the house after he tuned it and I rode up and down the street. I'm half nervous to get it back out and see what it'll do tonight, so fingers crossed. It's just making me want to go to a 1X even more.
Of course as I was stranded in the woods nearing dark, Mrs. Supe and Junior bailed and then accidentally took the wrong trail. Rather than do the sharp turn, they kept going down the "tunnel trail" which is the long one that links the two distant greenway areas. When Junior got back to the truck, she was covered head to toe in mud. Apparently she went flying down a hill into a giant mud pit which happened to have a root in it, and went flying off the bike. Thankfully, the bike is OK.
