There are a couple of changes that I'd like to make, but overall it's very close to exactly what I want. Current gearing is 34x19.
Did the parade lap just to feel the roll. Rolls very easy. A couple of brake and saddle tweaks and I was back on to head out for my lap. First two bridges felt good and I noticed that the bike when uphill far better than my old SS. I attribute that to the huge weight difference... especially in the wheelset and tires. I got into the first singletrack and tried to get a flow going. The bike responded well and went wherever I pointed it. That can be both good and bad in my case. It was also quite apparent that I chose wide bars. Tagged a couple of the trees.
As I got into the more rocky parts of the trail, I noticed that the front felt twitchy. Thoughts are I'm no longer used to a rigid fork, the contact patch on the 2.4 was just grabbing more or tire pressure was too high and I was bouncing off the rocks. I'm going with pressure at this point. I don't quite have this tubeless thing figured out yet. Heck, I'm still nervous about not having tubes. I get plenty of input from others about pressure from others, but I'm also nearly twice the size of some of the others.
I was able to roll the rock gardens better than ever. Got up some climbs that I didn't think I'd make my first time out. The tighter sections where aim and go. Steering didn't require much input. The bike is quick and even more comfortable than I thought it would be.
It all added up to the best first lap I've ever had.
